Kevin, with your specs and cam you listed,4 advance,and a 60 cc head, I got 9.94 compression and a 7.67.dcr . Seems like its close enough to work, and you can always use the .040 head gasket if you need to drop compression slightly. I did use the jeep stroker website. So it may vary slightly from other calculators. Personally, I would push alittle more compression, and if needed, Scott Brown can get a .050 head gasket to drop compression a bit more. I believe with the head flow, sp3 intake, your gonna see a higher rpm range then most 350s run. But the rods and pistons are much stronger than stock. A 58 cc head nets about 10.17 scr and a 7.84 Dcr. You could go to E85 also with carb recalibration .
