BTR HyperDrive SBC: The Bracketless Drive Comes To The Small Block

The small block Chevy has worn just about every front drive ever bolted to an engine since 1955. Short-pump V-belts, long-pump V-belts, chrome serpentine kits hung off three brackets and a fistful of spacers. At SEMA 2026, Brian Tooley Racing debuted the BTR HyperDrive SBC, the company’s first accessory drive for the original small block and a direct sibling of the HyperDrive system LS and LT guys have been running since last year.

The surprise is how little BTR had to change. The alternator, water pump, A/C compressor, and power steering pump all carry over from the LS kit we broke down in our BTR HyperDrive LS and LT accessory drive feature. Only one part on the front of the engine is unique to the small block, and it sits at the bottom of the belt path.

What Makes The BTR HyperDrive SBC Different

The crank pulley is the only real difference between the BTR HyperDrive SBC and the LS version. The LS kit uses a combined damper and pulley. The small block system gets its own dedicated crank pulley, and every accessory above it is the same hardware LS builders already run.

That commonality matters. Every mile the LS kit has racked up since launch applies here too, and replacement parts come off the same shelf no matter which Chevy V8 sits in the bay.

Same Bracketless Hardware Up Top

Plenty of SBC serpentine kits still hang each accessory off its own bracket. The HyperDrive ties everything to a single machined manifold plate, so belt alignment is built in instead of shimmed in with washers at midnight. BTR rates the system for 7,500-plus RPM, which covers any small block with a street cam and plenty with a solid roller.

The parts on that plate earn their spot. The USA-made 150-amp alternator uses square-wire hairpin windings that hold output at idle, which you will appreciate the first time an electric fan and a stereo load up in traffic. Power steering comes from an aluminum Saginaw Type II pump with ball-bearing internals and a baffled reservoir. A/C runs through an SD7-type seven-piston mini compressor, and coolant moves through a cartridge-style water pump with a mechanical seal. Everything wears BTR’s TRUE BLACK finish.

Why Small Block Builders Should Care

A 350 lives in more project cars than any engine ever built, and most of those cars still run a front drive designed around a 1970s bracket. The BTR HyperDrive SBC gives an old-school small block a clean, modern front without a junkyard brainteaser. Open the hood and you see the engine, not a stack of steel.

If you are planning a street small block like the Hot Rod Brawler SBC 355 or sorting out a fresh short block like we did in our SBC 350 rebuild, this is the kind of front drive that makes the build look finished. Keep an eye on BTR’s accessory drive page for the SBC listing.

Frequently Asked Questions

The small block has outlasted every trend the aftermarket has thrown at it. Now it gets a front drive engineered as one piece instead of pulled together from a parts bin, and that is reason enough to finally unbolt those old brackets.
