Kevin,

I think you can go a little more aggressive with the cam. I had a hydraulic roller in my .020 over Cleveland rebuild in my other Pantera ('74). It pulled from 1500 to 6500 smoothly and powerfully.

The specs were: 236 int & 244 exh on a 112 lobe separation with about .600 lift, installed straight up.

I had 10.5:1 compression with stock 4bbl heads that were converted for an adjustable valvetrain, and bowl blended. I used intake and exhaust port plates with a TorkerII and a Holley 750vac sec. It was a great combo!

It was a total street motor (my intention) and there were absolutey no issues with it's street manners. I thought the idle would 'rump' more, but roller cams reduce it with their smoother action.

I'd go with something like a 244 & 252 @ .050 on a 112 lsa with .600ish lift. Your extra cubes will absorb the extra duration yet deliver more power right up to your 6500 RPM limit.

Just my opinion.
