If you end up with 400+ torque, you will be happy enough and will forget that HP even exists.Įxample: a 262H is a good selection for a 350 and the 268H or 274H on a 383 since bigger CI can make a cam look smaller. Ignore HP since you are asking about building power down low. ![]() Higher vacuum means good carb signal, good brake booster response, and good MPG down low. If the peak torque is close across the cams you've narrowed down to, I'd select a cam with the highest vacuum in your case. Note the vacuum profiles as you move up through the cams. ![]() A rule of thumb but not gospel is that as you move up in duration, you typically move up in RPM for the power band.Īnything from 262H - 274H would be good for your application. When it comes to cams for low-end, if it has a rumpy idle, and vacuum < 11" at idle, it's NOT what you want. Even if you don't use one of their cams, it's good learning. look at the dyno graphs on the Comp site and their brief recommendations of cam profiles. If you plan to tow serious weight, a forged crank might be a good upgrade just for the extra torque capacity.įor cams. 2-bolt or 4-bolt mains would be fine in your case. Or you can build it for gobs of low-end torque. Also if budget allows, get a stroker crank.
