Need help/496 BBC

[TT LS2]

I had a similar build that i sold in order to build a TT LS2. I had a .060 over, 4.25 stroke, DART Pro 1 heads, with 325 intake runners and a solid Herbert roller with .680/.688 lift, 11.0:1 comp. ratio all backed by a Richmond 6-speed. Not really sure about dyno specifics, but I do know the engine had an enormous amount of torque. I think the cam that I chose was a little on the mild side in terms of lift. It had alot of duration something like 256/268 @ .050. The engine was very strong as well as responsive. In a 69 Camaro with a 6-speed, it was really nice. Just remember, rectangular ports usually work better in a strip/drag car. Oval ports make a better choice for BBC that pretty much live on the street. Be sure to be honest with yourself reguarding the use of the vehicle and choose a cam that will deliver the power that you want for the type of driving that the car will regularly be used for. It's all about a happy medium! Good luck with the build. Keep us posted.
