Wanting 550 to 600 on 92 pump gas. Starting with 850 demon and a stroked 440 around 500ci I know I can get it. Cam size. lifter, rocker length, heads? Not A stock build. PS! I wish it was 68 Road Runner. Rusto mod.

600 hp is easy to do these days but you have to be super careful on the cam selection if you want it to be easy to drive. I've built a bunch of 600+ hp big block Mopar engines over the past 10 years but the one I have in my Coronet now is the most friendly one. It is 9.8 compression, Trick Flow 240 heads, port matched Trick Flow intake and a custom hyd roller cam. The cam has to be big enough to make the power up top but it can't be too big or else it kills torque down low. Very much a balancing act.

4.250 stroke, 10.5:1, trick flow heads, and a Dwayne porter solid and you’ll make 600 all day long.
