I'm building a 440 stroker with a 4.150 eagle crank eagle h beam rods Srp pistons. Looking for recommendations for the top end of the motor. Pistons would be 11:1 comp with 84cc heads. Want to run on pump gas and make 650 hp. Was looking at the trick flow 270 heads. Also want to use a roller cam. Hydraulic or solid. Also would like it to fit under the r/t hood on my 70 challenger Thanks in advance.
