X block, 4" stroke 360-1 Indy head build questions

You will not like hyd. roller in this application. Solid roller would work great, but if we build it and dyno it, the flat tappet cam will work fine. Remember, 1.7-1.6 rockers so you'll get decent lift. Like I said, figure 575-600HP depending on the cam and other things like just how good the heads are, etc...

I'm changing out a hyd. roller setup in a SB Chevy for a local customer I had built an engine for. He street races for $$$ around here, and so far has not lost but he's over revved it hurting it multiple times. So stick with solid FT or solid roller IMO!
