The 470 that Compu-Flow is building for me will have the 270's. Not sure on the cam yet but we both kind of want to try the trick flow cam. I will be thrilled if this engine is a legit 600 hp.
A pump gas 470 with 270 heads and the TF hyd roller cam will make 600 hp on the dyno as long as you use a good intake manifold. Best intake if you want 600 hp would be a port matched TF intake.
