I have got a 340. 69 block .30 over with stock dome style pistons, ported j heads, eddy performer rpm intake and I purchased a holley street avenger 670cfm carb. the car currently has a comp extreme energy 260 cam. I am new to engine building And would like to have a streetablw cam that still makes great power. I am wanting a choppy idle and was I had planned on buying a hotter cam before I install my motor. do toy guys have any suggestions? I'm willing to sacrafice a little driveabilty for power since it is not my daily driver. It's also 9.5/1 compression.
