My 493 10.5-1, 590 mopar cam, edel rpm heads 600hp

Upgraded to indy ez and solid roller made around 720hp

426 6.1 base. Eagle heads. 10.5-1, .600 lift hyd cam 620ish hp

That upgrade on the BB cost alot of money. I put aluminum caps in the motor when I upgraded because I got "nervous". Roller cam and everything that goes with it. Very spendy. Going over that 600 mark seems to get much more expensive
