Best Sbc Electric Water Pump Alternator Bracket for Small-Block Chevy

#1 · Best Overall

1. ICT Billet SBC Bracket

• Material: Alloy Steel, Aluminum
• Compatible with Vehicle Type: Car
• Weight: 1.4 lb

Best for: Electric-pump V-belt conversions.

Why it ranks #1: Specifically fits Chevy long-water-pump V-belt systems, uses slotted belt tension adjustment, and includes bolts and hardware for alternator mounting.

A slotted tension design is the defining feature of ICT Billet’s SBC bracket, letting builders adjust belt tension while replacing a stamped factory bracket that may not work with electric water pumps. Its billet-aluminum construction and included mounting hardware make it a focused option for Chevy long-water-pump V-belt setups.

The bracket is specified for small-block Chevy engines including 305, 327 and 350 applications, and for long water pump V-belt arrangements. That combination helps narrow the fit decision before installation. A slotted tension path provides belt adjustment, while the kit includes bolts and hardware to mount the alternator. The satin-finished, American-made billet aluminum construction replaces the factory stamped-steel style; this is not a general serpentine-system bracket, since the listing specifies V-belts only.

Skip it if you need a serpentine arrangement; March Performance 22025 is listed for both serpentine and V-belt use.

For a Chevy small-block owner converting to an electric water pump while retaining a long-water-pump V-belt layout, this bracket offers adjustable tension and supplied hardware. Keep its V-belt-only application in mind before choosing it.

#2 · Broad Pump Fit

2. CVF Racing SBC Bracket

• Weight: 2 lb

Best for: Broad SBC electric-pump coverage.

Why it ranks #2: Fits SBC engines from 283 through 400 and lists compatibility with several electric-pump brands; hardware is included, but fuelie heads are excluded.

Compatibility with electric water pumps from CVF Racing, Meziere, CSR, PRW, ProForm and CVR distinguishes this CNC-machined billet bracket. It gives small-block Chevy builders several named pump choices while placing the alternator on the passenger side in a mid-mount V-belt arrangement.

The bracket covers SBC 283, 302, 305, 327, 350 and 400 engines, giving buyers a broad stated engine range. Its passenger-side mid-mount position is specified for V-belt applications, and the listed pump compatibility spans several brands, which can simplify selection around an existing pump. Mounting hardware is included. The alternator and electric water pump are not included, and the listing says the bracket will not work with Fuelie heads; pulley alignment also calls for the specified crank-pulley pairing.

Skip it if you have Fuelie heads or need the alternator and pump included; Chap Performance SBC-350 EWP ALT is another bracket option.

A builder with a listed SBC engine and one of the named electric pumps can use this for a passenger-side V-belt mid-mount arrangement. Check the Fuelie-head exclusion and source the alternator and pump separately.

#3 · Machined Billet

3. Chap Performance EWP Bracket

• Material: Aluminum,Stainless,Steel
• Compatible with Vehicle Type: Small Block Chevy

Best for: Measured GM alternator fit.

Why it ranks #3: Made from 1/2-inch 6061-T6 billet and specified for electric pumps with long-water-pump pulleys; supports GM alternators at 6 or 12 o'clock.

A 6 5/8-inch pivot-to-adjusting-hole measurement makes Chap Performance’s EWP bracket unusually specific about its alternator geometry. CNC-machined from 1/2-inch 6061-T6 billet aluminum, it targets a small-block Chevy electric water pump with long-water-pump pulleys and GM alternators in either listed clock position.

The stated 6 5/8-inch distance between pivot and adjustment holes helps buyers compare the bracket with their alternator layout before installation. Compatibility with GM alternators at 6- and 12-o’clock positions adds another concrete fit reference. Its passenger-side mid-mount placement and long-water-pump-pulley application define the intended engine arrangement. CNC machining from 1/2-inch 6061-T6 aluminum supplies the bracket construction, but the listing does not give a complete engine displacement range.

Skip it if you need a stated list of engine displacements; CVF Racing 350-ALTBRKT-C-EWP lists SBC 283, 302, 305, 327, 350 and 400.

Choose this for a small-block Chevy build using an electric pump with long-water-pump pulleys and a GM alternator matching the stated clock positions and hole spacing. Its listing leaves the displacement range unspecified.

#4 · Alt Size Range

4. March Performance 22025

• Material: Aluminum
• Compatible with Vehicle Type: Car

Best for: Flexible belt-drive configurations.

Why it ranks #4: Designed for electric water pumps and 6- or 7-inch GM alternators; includes a stainless tensioning rod and works with serpentine or V-belts.

Support for both serpentine and V-belt systems separates the March Performance 22025 from brackets limited to one belt style. It is listed for a small-block Chevy electric water pump, passenger-side placement and GM alternators with 6- or 12-o’clock mounting, with a stainless tensioning rod included for belt adjustment.

The bracket accepts a 6- or 7-inch-diameter GM alternator with 6- or 12-o’clock mounting, providing useful fit criteria before installation. Its stated compatibility with both serpentine and V-belt systems gives builders more drive-layout flexibility than a single-style listing. A stainless tensioning rod supports belt adjustment, while the passenger-side placement clarifies the mounting location. The silver powdercoat is specified as the finish; the listing does not name particular pump brands or SBC displacement ranges.

Skip it if you need named pump-brand compatibility; CVF Racing 350-ALTBRKT-C-EWP lists several electric-water-pump makes.

For a small-block Chevy build where belt style or alternator diameter may vary, this bracket’s dual belt-system listing and tensioning rod are useful. Its pump-brand and engine-range details are not specified, so verify those against the build.

5. GSKMOTOR EWP Bracket

• Compatible with Vehicle Type: Car
• Weight: 0.67 kg

Best for: Passenger-side EWP and LWP setup.

Why it ranks #5: Described as a passenger-side middle-mount bracket for an electric pump with an LWP pulley, with slotted tension adjustment and mounting hardware.

A passenger-side, middle-mount alternator position gives this GSKMOTOR bracket a clear role in an SBC electric-water-pump layout. Its listed compatibility with an electric water pump and long-water-pump pulley configuration helps buyers target a specific arrangement, while the slotted tension design supports belt adjustment during setup.

The bracket is described for a small-block Chevy electric water pump and a long-water-pump pulley, so those details help define the intended cooling-drive arrangement. Its passenger-side middle-mount position identifies where the alternator sits. A slotted tension design gives the installer a way to maintain belt tension, and the included bolts and hardware support mounting the alternator. The listing does not provide an engine-range list or alternator-position dimensions, so confirm those details against the build.

Skip it if you need a stated engine range or measured alternator-hole spacing; Chap Performance SBC-350 EWP ALT lists a 6 5/8-inch measurement.

This suits an SBC builder seeking a passenger-side middle mount for an electric water pump with a long-water-pump pulley. Its listed features cover basic layout and tensioning, but buyers needing documented engine ranges or dimensions should account for their absence.

6. Topteng 551672E Bracket

• Weight: 0.75 kg

Best for: 12si-style alternator mounting.

Why it ranks #6: An adjustable electric-water-pump mount kit with a listed 6.56-inch center-to-center bolt-hole measurement for 12si-style alternators.

The stated 6.56-inch center-to-center bolt-hole spacing makes this Topteng bracket particularly relevant to 12si-style Chevy alternators. Its adjustable electric-water-pump mount kit is identified by the 551672E designation, giving buyers a specific dimensional reference for comparing their alternator before selecting a mount.

Topteng identifies this as an adjustable electric-water-pump alternator bracket for Chevy and calls out 6.56-inch center-to-center bolt holes for 12si-style alternators. That measurement gives the buyer a concrete check for alternator mounting compatibility. The listing describes aluminum and alloy-steel materials and a lightweight construction, which characterize the hardware without establishing a complete engine or pulley range. It does not provide a detailed pump-brand list or installation hardware inventory, so those specifics are not established here.

Skip it if you need named pump compatibility and confirmed mounting hardware; ICT Billet 551672E lists hardware and a Chevy long-water-pump V-belt application.

This is most useful when a Chevy builder has a 12si-style alternator and can compare its mounting holes with the stated 6.56-inch spacing. The listing leaves pump brands and hardware contents unclear, so those are key boundaries.

7. Chap Performance SBC10013-A

• Material: Aluminum
• Compatible with Vehicle Type: Car

Best for: Dimensioned passenger-side LWP mount.

Why it ranks #7: CNC-machined from 1/2-inch 6061-T6 aluminum for a long-water-pump mid-mount layout; the listing does not specify electric-pump compatibility.

A 6 5/8-inch pivot-to-adjusting-hole measurement gives this Chap Performance long-water-pump bracket a practical alternator-fit reference. Its CNC-machined 1/2-inch 6061-T6 aluminum construction and passenger-side mid-mount placement identify it for a small-block Chevy LWP arrangement with a GM alternator.

The measured distance between the pivot and adjustment holes helps buyers compare the bracket with their alternator mounting geometry. It is specified for GM alternators at 6- and 12-o’clock positions, adding a second fit detail. The long-water-pump, passenger-side mid-mount configuration defines the installation layout, while CNC-machined 1/2-inch 6061-T6 aluminum describes its construction. The supplied facts also warn that it will not work with Fuelie or Camel Hump heads.

Skip it if you have Fuelie or Camel Hump heads; Chap Performance SBC-350 EWP ALT is a different bracket listing without that stated head exclusion.

This is a fit-focused option for a small-block Chevy long-water-pump build using a GM alternator with the stated clocking and hole spacing. Fuelie and Camel Hump head incompatibility is a firm boundary.

8. Chap Performance SBC10012-A

• Material: Aluminum
• Compatible with Vehicle Type: Car

Best for: Circular-pattern LWP bracket buyers.

Why it ranks #8: A long-water-pump passenger-side mid-mount bracket with 1/2-inch 6061-T6 construction and a 6.6-inch pivot-to-adjusting-hole measurement.

The “New Circles” title distinguishes this Chap Performance bracket within the long-water-pump SBC group, while its listed 6 5/8-inch pivot-to-adjusting-hole measurement supplies the key alternator reference. CNC-machined 1/2-inch 6061-T6 aluminum and passenger-side mid-mount placement define its construction and layout.

Chap Performance lists compatibility with GM alternators at 6- and 12-o’clock positions and measures 6 5/8 inches from the pivot hole center to the adjustment hole center. Together, those details give buyers concrete mounting references. The bracket is a passenger-side mid-mount for small-block Chevy long-water-pump setups, and its 1/2-inch 6061-T6 aluminum construction is CNC-machined. The supplied facts warn against use with Fuelie or Camel Hump heads, a decisive engine-head fit restriction.

Skip it if you have Fuelie or Camel Hump heads; GSKMOTOR GSK-2287132 is listed for long-water-pump 305 and 350 engines without that stated head restriction.

A small-block Chevy owner with a long water pump and a GM alternator matching the listed clocking and spacing can consider this passenger-side mount. Its Fuelie and Camel Hump head exclusion remains a key fit boundary.

9. Chap Performance Low Mount

• Material: Aluminum
• Compatible with Vehicle Type: Car, Truck

Best for: Driver-side low-mount LWP builds.

Why it ranks #9: A CNC-machined driver-side low-mount bracket for long-water-pump applications, but its listing does not establish electric-water-pump compatibility.

A driver-side low-mount position gives this Chap Performance bracket a different placement from passenger-side mid-mount options. It is specified for a small-block Chevy long water pump, with hardware and installation instructions included, helping buyers identify both the mounting layout and the basic installation provisions.

The long-water-pump application is the central fit requirement, while the low-mount driver-side position determines where the alternator sits in the engine bay. Those details make it relevant to builds that need this specific layout rather than a passenger-side mount. Chap Performance identifies the bracket as CNC-machined billet aluminum, and the listing says installation hardware and instructions are included. No alternator clocking, hole spacing, belt type or displacement range is supplied in the provided facts.

Skip it if you need stated alternator clocking and hole spacing; Chap Performance SBC-350 EWP ALT gives both clock positions and a 6 5/8-inch measurement.

This fits a builder seeking a driver-side low mount for a small-block Chevy long-water-pump layout, with hardware and instructions included. Because the listing omits alternator dimensions and belt type, those details remain important fit boundaries.

10. GSKMOTOR LWP Bracket

• Material: Alloy Steel
• Compatible with Vehicle Type: Car
• Weight: 1.17 kg

Best for: Steel passenger-side LWP brackets.

Why it ranks #10: Made for SBC 305 and 350 long-water-pump configurations from heavy-gauge steel; the listing specifies long-pump fit, not electric-pump compatibility.

Heavy-gauge steel construction is the defining choice in this GSKMOTOR bracket kit for Chevy 305 and 350 engines with a long water pump. Passenger-side mounting and included upper- and lower-bracket hardware identify a conventional LWP arrangement, rather than an electric-water-pump-specific setup.

The stated fit covers small-block Chevy 305 and 350 engines configured with a long water pump, making pump length a key selection check. The bracket mounts on the passenger side, and the kit includes hardware for both upper and lower brackets, supporting installation of the listed assembly. Heavy-gauge alloy steel distinguishes its material construction. The product information explicitly limits use to long water pumps and directs short-water-pump builds to a different bracket type.

Skip it if you use a short water pump or need an electric-pump-specific mount; ICT Billet 551672E is listed for electric-water-pump V-belt use.

This suits a Chevy 305 or 350 owner installing a passenger-side alternator bracket with a long water pump and steel hardware. Its long-pump-only limitation rules it out for short-water-pump configurations.
