Chevy LS Application Info

LS Chevy Engines

These kits fit non-VVT or VVT deleted LS series and other GM Gen III and IV engines including but not limited to LS1, LS2, LS3, LS6, LS7, LSX, L92, L99, LQ4, LQ9, LY6, L76, all Vortec 4800, Vortec 5300, Vortec 6000, and Vortec 6200

 

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.

That being said, issues such as age, condition, manufacturer, etc. of motor mounts can cause clearance problems.  Fortunately, most clearance issues can be solved by putting a spacer between the engine and the motor mount.  This was a factory solution for GM on 1966-74 big block Corvettes with air conditioning.  The factory style spacers are reproduced and are available from various Corvette suppliers listed below.  They are specified for big block, but they will fit Chevy small block engines as well.

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!

Part numbers for the engine mount shims:

GM #3910756 (for reference only, no longer available)
Corvette Central #302001, www.corvettecentral.com
Mid America Motorworks #670-199, www.mamotorworks.com
Volunteer Corvette #EN65X, www.volvette.com
Zip Corvette #M-2494, www.zip-corvette.com


Additional Notes

  • This kit will not work with engines equipped with VVT (variable valve timing).  VVT components can be removed with VVT delete kits available from Summit Racing, Brian Tooley Racing, etc.
  • LS kits will work with most cable driven, LS1, LS2, LS3 and aftermarket throttle bodies
  • Thermostat part number for this waterpump is a GM #12600171 and requires seal GM #12570307 (common application: 2005-2007 Corvette 6.0L), thermostat housing kit is GM #12600172.  Alternate/OEM Part Number(s):  MotoRad #456-187 (includes seal), Stant #14948
  • LS7 engines require a slightly different crank pulley configuration. Please let us know when ordering if your engine is an LS7
