GTM engine pulley spacing

[Power Surge]

Does the GTM use the Corvette LS1 or the Camaro/Firebird LS1 belt pulley spacing?

Corvette spacing on everything. If you're doing a crate engine, you will have to install the older C5 water pump that has the large bell-shaped pulley. The newer waterpumps with the flat pulley are too thick at the t-stat housing and the housing will hit the chassis.

Thanks Shane. Not doing a crate motor, but working on something that requires the proper spacing :cool:
