First off, I've kind of asked this question in other threads but wanted to try again to get anyone's experience actually building such a motor: 383, either massaged 906 or CNC'd Stealth heads, roller Lunati cam, 231/239 @ .50 535/550 lift, either 3.75 or 4.25 crank for 432 or 489 c.i., stock HP...

I know I should pull & store my Roadrunner's numbers matching 383, but what I will be doing instead is building it to a 'safe' power level and just not abusing it unnecessarily; no burnout contests, limited track time, mostly cruising and 'feeling the power' from time to time. At what power...

I already have this cam for a 383/432 build. I'm now considering a 383/489 build for 1) a stock 'looking' build with 906 heads, exhaust manifolds and DP4B intake or 2) CNC'd Stealth heads, headers, and probably a six pack setup. I'd like some decent lope but nothing too radical. Will this cam...
