My two cents.

One, does your engine need an overbore? If not then just run the low comp pistons you have. It is tough to run a 9 to 1 440 with open chamber heads and no quench on anything but 93 or higher octane.


With the summit cam you chose, I would just run the stock intake. No reason to spend money on a performer or perf rpm with your combo in a truck that likely will not see north of 5500 rpm.

Now about that cam. If you follow the above and are not spending a bunch on pistons, overbore, and intake, spend a little extra and get a modern cam designed specifically for your combo. It will cost a little more, but will make the biggest bang for the buck. Mike Jones would be a good guy to talk to about the cam selection.
