Dyno testing a stock(?) 1972 440

Well here's a back in the day (1989) low budget build I did with a 440-6pk motor for the race car with .039" f/pro's so it was prob only around 9.5>9.8:1? with bone stock 906's, I had the idea to go up in the CR dept. at a later date once I was a bit more flushed with money so ordered the Comp Cams [email protected], .650/.650" sft cam and as we know this cam requires 12.5:1, 5000 stall/gears etc. well the CR hike never happened as funds didn't allow but I did have a 4800stall and 4.88's, that stock motor made 460 f/wheel track Not dyno hp (elec w/pump-no alternator) with a s*it Team G intake and an 850DP, 2" f/wells, nothing amazing I know but it ran good with that big cam, changed nothing else but some bv 260-ish cfm 906's and power went up to 527 basing all this on weight/mph, how much faster it would've [email protected]:1 well we'll never know, certainly not .5+ in the 1/4.
