Extensive engine dyno testing at Lingenfelter has produced some of the best street camshaft profiles available for the LS1, LS2, LS3, and LS6 engines. The Lingenfelter "GT1-1" Camshaft was designed to produce excellent power with a aggressive or rough idle and is only suggested in six speed manual transmission equipped vehicles or automatic transmission applications with a loose torque converter.
This camshaft was designed to be used in LS1, LS2, LS3, LS6 350 CID - 427 CID applications. Spring & retainer upgrades are a must with this camshaft. This cam should not be installed in LS engines without modifications to stock pistons. Piston to valve clearance should also be checked with aftermarket pistons.
All Lingenfelter camshafts ground by Competition Cams to Lingenfelter specifications on induction hardened cores for exceptional durability and long life.
