lo po cam dilemma

I recently re rung and stuffed new bearings in a low mile, low compression rv 440 to replace the one that turned a bearing on break in. the 292 comp that was in the engine will be a little to much for the factory geared 8 1/4 and stock converter that were to be replaced. funds are a little tight right now thanks to this and I would like to get this thing on the road for once. so the question is I have a summit k6400 cam with the lifters and also the stock rv grind that was in the engine what will be better? specs are stealth heads, performer intake, factory 76 bottom end with new rings and bearings, Schumacher tri y's in a 73 duster with a 727 and 2.76 axle ratio with 26 inch tires. what does everyone figure it will run too? would be nice for some educated guesses. can't afford much thanks to this terrible canadian exchange rate and everything listed is just kind of kicking around. thank you for your time.
