Go over to moparts and look up Triple Threat's "My bracket Hemi build". He has Apache instead of Eagle heads. 5.7 based 392. Chassis dyno'ed at 515 to the tire with convertor wanting to flash like 6300. He's in the nine's. I have a 6.1 based 426 that engine dyno'ed at 730 using cnc ported early heads. I would love to do cnc Eagles and see what happens.
