Hop Up Your Chevy TBI or L98 Engine with a Summit Racing™ Pro EFI Stage 1 Camshaft

For all of the attention GM’s LS series engines get, there are still lots of 350 cubic inch TBI, L98, and LT1 engines under the hoods of Camaros, Corvettes, and GM trucks. This Summit Racing™ Pro EFI Stage 1 Camshaft is just the ticket for adding some much-needed horsepower. The solid billet hydraulic roller cam pulls strongly from 1,500 to 6,000 RPM and has a lumpier idle than stock so people will know there is something interesting under the hood.

The Pro EFI Stage 1 Camshaft is compatible with the factory tune on TBI, L98, and LT1 engines. If you have a mechanical fuel pump, you’ll need to use a bronze or carbon-polymer tipped fuel pump pushrod to prevent premature lobe wear. You’ll also need to use a steel or melonized distributor drive gear as a bronze gear is too soft and will wear quickly.
