I have a 454 in my camaro. It is new,but it was built for a different car than mine. I took it apart and checked everything before it went in to the car.It has 10.5 to 1 comression, 049 oval port heads and a rpm airgap intake on it. I have a 825 mighty demon carb on it right now. The cam is a comp xtreme energy 262 with .505" lift and 218 @.050 duration. The rest of the car is pretty basic as well. B&M 10" holeshot convertor, turbo 400 with a shift kit,and a 9" rear with a 4.10 gear and a detroit locker in it. I would like to get into the 11's with out spraying it.The car is only a weekend toy but I want it to be a little quicker.
