That's what we based Clayton's build off of with the exception of, Eagle heads , and Hemitronix's VVT delete kit.
With Hughes Cam SER4650 (.611/.642 246/250@50 our dyno numbers were 12-15HP better on average with the eagle heads with max HP of 775@ 7400.
Howards Cams 786045-14 .600/.600 227/233 , made 719@ 7200 but TQ was above 500lbs from 4300-7400.
Next will be a custom VVT based cam to get ride of the Hemitronix deal.
How bout one step further and use apache heads on a bigger bore 6.2/6.4 block?
Clayton and I have been debating over the last few months as to what should be next Apache heads or T&D Rockers. I say Rockers, because we know it'll make more HP with either, but Apaches head prices will come down, and there's always a chance of finding them. T&Ds I doubt we'll see a lower price on them.
I have 2 hellcat block builds that are waiting on more funds, 1st is a 4.12X4 426CI using 6.25 rods for a RR 1.56 and a 1.02ph JE&E customs , he has Apache heads for it. just no money to finish it
2nd is for my niece Caroline, 4.12X3.724 397CI with 6.30 rods RR 1.69 and 1.095 PH Manley's, she too is going Apache head,
since this is going in a 08 Magnum her dilemma is intake.
