Extensive engine dyno testing at Lingenfelter has produced some of the best street camshaft profiles available for the LS1, LS6 & LS2 engines. The Lingenfelter "GT" series camshafts were designed to produce excellent power while still producing a smooth idle for automatic or six speed manual transmission equipped vehicles that can be daily driven.
This camshaft was designed to be used in LS7- 427 CID applications. Spring & retainer upgrades are a must with this camshaft. This cam can be installed in stock LS1 engines with no changes to pistons if you install it straight up. It is not suggested to advance or retard this cam with stock pistons.
All Lingenfelter camshafts ground by Competition Cams to Lingenfelter specifications on induction hardened cores for exceptional durability and long life.
