Looking for a viable manual transmission to put behind a Chevy small block, big block and BOP V8?  This Quick Draw Brand Adapter Kit provides a simple solution for bolting any engine from the 1st Generation GM small-block, big-block, or BOP (Buick, Oldsmobile, Pontiac, Cadillac) families to a GM SM465 4 speed. Further, our adapter kit is designed to use mostly off-the-shelf parts that can be sourced at any auto parts store. Our GM SBC / BBC / BOP engine to SM465 Adapter Kit utilizes a factory Chevy flywheel, starter, and clutch kit.  On top of that, we designed our bellhousing adapter to use a 1999 Jeep Wrangler external slave cylinder, which resolves the clearance issues that other adapter kits on the market don’t address and can be challenging to overcome.

Our General Motors SBC / BBC / BOP engine to SM465 adapter kit works with all GM v8 style engines matching the small-block, big-block, or BOP bolt pattern. Further, it works with 4-speed transmissions that were used in GM 1 ton trucks from the mid 80’s.

Kit Includes:

  • Bulletproof Chevy CBS / BBC / BOP to GM SM465 bellhousing
  • Lifetime use throwout bearing carrier that accepts the factory LS throw out bearing
  • Pilot bearing insert to use a Jeep pilot bearing in the sbc flywheel
  • New clutch fork, fork spring retainer, and pivot ball
  • All hardware to attach the bellhousing to the engine and transmission
  • Dust cover with bolts
  • External Slave cylinder bolts
  • Index ring
