Its been 25 years since I bought a cam and need some help,I have a stock 70 302 in my 65 custom 500 and I want a little hotter cam. The car has a manual trans with a 3.00 rear gears,truck shorty headers with 2 1/2 duals all the way back and a holley 500 CFM 2 bbl untill I convert to EFI. Since its been so long I need some help in deciding what cam would be best for my motor as I do not want to kill low end torque. Jeff
