This is my very first 426 hemi build and I really need some guidance from the guys here that have built one or more and here’s what I have to build on. 1970 block 4.310 bore that has a deck height of 10.612 with a 4.250 stroke crank with 7.1 rods and diamond 108 cc dome pistons. So to bring the compression down and get the heads back up to be able to use a factory type intake I thought of using a cometic MLS .140 head gasket. I ran all my numbers in the diamond compression calculator and come up with 11.1 : 1 ratio with a 4.310 bore gasket and 170 cc combustion chamber. I would like to use the standard Stage V heads with some port work and a 2x4 inline mopar performance intake with 600 cfm carbs and a mechanical roller cam of which I have no idea of which would be best for the combo in mind. The car is a 69’ bee with a hemi 4 speed and 3.91 gear I hope to make around 600 to 650 HP and equal amount of torque. Please keep in mind these things are only my idea so I would like to know if this seems like a good combo or if not please school me on what would work best together with the short block I have and will run on 93 pump.
