i can only relay what i'd expect it to make on the dyno i use, which has been extremely close when compared to MPH at the track. your likely to make between 550-565 honest HP IMO.
that's a small cam with unported heads but yet a ported intake. i'm not too concerned about the C/R or the carb, that's a pretty typical street type build for pump gas. in the end it makes whatever it makes. if it runs good enough for you, then it makes all it needs to make regardless of the actual number.
run it down the 1/4 mile once or twice and you'll pretty much know what it really makes.
