i timed my car's 0-60 from idle to 60 it took 6.5 seconds. Is this good should it be better? I have 416 heads on a 79 350. I have a street dominator intake, edelbrock 1405, comp 270 h-10. I seemed to have lost some low torque from the old camshaft, but it seems to rev a lot faster. I figure if I got the engine into the cams power band by doing a power brake up until around 1800 rpms I could improve that time. I have the stock rear end, but I'm not sure what the ratio is.

 

It is very common for a higher lift, longer duration cam profile to cause an engine to lose lower RPM torque, but gain higher RPM torque (peak HP). A more slack torque converter, higher ratio gearing, or higher speed operation will get the engine into the RPM range that the cam profile supports best.

 

what rear end would you suggest?
