Comp cams xe268h for 318

Here is some more brainstorming if you do the math 3.31/2=1.655 + 6.123 for the rods - 9.6 for the deck that puts us at 1.822 (max compression height at top of the block) so if I am .1 under the block then that leaves us a piston height of 1.722. The largest c h piston i can find in the cheap range (ie speed pro etc) is 1.755 with no eyebrows. That will put me at 8.78 then if I could mill my heads a little let's say .020 that that will put me at 9.18. That Is about where I want to be. That is still gonna run me about 140 for the pistons plus machine shop labor for getting the pins pressed and heads milled. But this would be a better bottom end. If the bores are good and not wore
