Horsepower guesses???

[lukendan]

I have a motor in my 69 Charger that was rebuilt, but I'm not sure what was done to it. This is what I know: It is a 1969 383 w/ 906 heads. It has mopar performance electronic ignition(spell?), headers, and a edelbrock Performer intake w/ Holley 650. Any guesses on horsepower?

well assuming the heads are bone stock and the compression ratio is stock for 69 i would muster a conservative hp guess at 350 hp and 400 ft lbs of tq based on the few bolt ons it has.

Just found out my Carb is a 600 CFM Holley #4160. Not a 650 like I thought. What would be the best size carb for my car?

what plans do you have for the engine? is it a stock cam? if you are leaving it mostly stock then a 650 would be good, if you are bumping the cam up and want more potential then go with a 750
