Hello Im new to the 5.0 pushrod group and wondered what it would take to get 500rwhp/500tq on pump gas (93). I want to do a single or twin setup, with a 331 motor and a trick flow intake. What heads would you recommend? afr 165,185? or trick flow twisted heads? Am i crazy for trying to get here with a stock block? On my twin turbo 01 corbra 5lbs of boost gets me 550, is it hard to make good number with a 5.0?
