wow, that was alot of help, I have 3932441 heads with 1.94intake and 1.5 exhaust with 76cc chambers, i think these will be good enough for my first build and plan on having them rebuilt because neither myself nor my dad have those skills, i think i may need a new crank because mine has grooves cut into a few of the journals i believe there called, i am thinking of using an edelbrock performer intake and 750cfm edelbrock carb, any suggestions on a cam manufacturer? This is all going thorugh a th350 with a mild shift kit to a stock g body rear, 2.50 or there about until it is gernaded then i am going with a 3.73 out of a monte ss or GN, by the way, that jeep is bad ass, and maybe a cam isnt as bolt on as i thought, i forgot about the accesories, oops
