Thanks for posting! That's a lot of solid info. How do these cars perform in the 1/4?

The Firebird is a 4-speed car, so has the factory 068 cam, and the Custom S is an automatic car, so has the factory 067 cam. Dan ran both engine set-ups on the DeskTop Dyno, and the 067 cam made the same hp as the 068, but with 10 lb-ft more torque. So, don’t over-cam your 350. Both cars have the std. 3.55 gears with the optional HD Safe-T-Track limited slip.
