Small Block Driver Application Info

Small Block Chevy Engines

These kits fit GM Gen I small block Chevy engines

Applications include a wide variety of vehicles from muscle cars and street rods to sports cars and late model trucks.  Always use the "Kit Dimensions" located on the previous page as a guide for measuring fitment for your particular application.

Will These Pulley Kits Clear the Cross Member on a C2 or C3 Corvette?

These kits normally clear the cross member on otherwise stock 1965 - 1982 C2 and C3 Corvettes. 1963 - 1964 engines will most likely have to be shimmed upward for the crank pulley to clear the cross member. Make sure you have enough hood clearance!

 


Additional Notes

  • Most Chevy blocks have drilled and tapped holes on either side of the harmonic damper, but a very few do not. All of our SB Chevy kits require these holes
  • Our kits will not work with engines mounted with front motor mounts. Side motor mounts are recommended

Additional Notes - Driver Series

  • Driver Series Kits will work with all heads including those without accessory bolt holes
  • Driver Series Kits are one belt serpentine systems with a spring loaded OEM tensioner
  • Driver Series Kits are designed for use with electric cooling fans. If you need to run a mechanical fan, contact us and we can make modifications to the waterpump pulley. Also, this kit uses a reverse rotation waterpump, so make sure the fan is a reverse rotation fan.
