I agree 1000% I did a very simple 400/470. Eagle crank, Manley 6.760 rod, Diamond piston, 10.2:1, box stock Eddy head w/springs for a Comp street solid roller, Eddy RPM intake, 800 Holley. Runs great, idles nicely at 850 rpm, pulls hard through the middle. On a chassis dyno it made 500 ft lbs from 2500rpm all the way up. Great little street engine...no muss no fuss
