here is a good tip, call up crower cams you can get their number from www.crower.com, ask for technical assistance for domestic cams, and then ask the question, tell him if you're using a stock valve train and everything, he should be able to get you the setup you need for a pretty affordable price. i paid $117 for a cam for my 302, runs with stock valve train gives about a 23% HP gain and a 17% torque gain in RPM bands 2200-5500, which matches my torque converter... also make sure to tell him what tranny you are using, if you're going with an automatic, make sure that you get something that fits into your shift speed, that way you get clean acceleration.... matching up with the computer on the other hand ussually isn't that big of a deal, the computer will ussually correct itself to the new valve lift, as long as your injectors are in decent condition, you shouldn't have much of a problem
