what should a motor like mine be putting down at the back tires?
Difficult to say.
My guess from what you posted, and no facts to base on... I'd say 270-300 at the wheels.
If you run it down the track... you'll know what it is. That will be a FACT.
Woah! I dont think so man. I would hope they are a lot higher than 270-300. Those are mild 302 numbers. It's a carbed stick car! Not an injected auto!!!!
A 331 with ported RPM heads and a Vic Jr intake should be putting down at least 350rwhp. (If all the supporting mods are done properly)
You're numbers are high...i would question the dyno calibrations. Perhaps another dyno session or some track times would give some more insight.
I have a 86 mustang gt with a 331 stroker, ported performer heads, unknown cam, 1.7 roller rockers, victor jr., 650 demon. It is a 5 speed car with the tremec out of a summit magazine. My question is it made 420hp and 404 tq on a dyno dynamics dyno at the rear wheels and I was wonder if that sounds right to you guys cause I was thinkin mabey it would make 375 or so at the back tires. If you need more information just ask and Ill tell you all that i know about the car.
How was it corrected, std or sae?
Alot say my numbers are fubar or the dyno wasnt good, my 306 put down 406 tq, 350hp at the wheels. That was rated at std, most use sae, and i think sae is what most quote, its about 4-5% less than std. So sae rated my car should be in the 330/380 range.
best test is the track, which mine hasnt seen yet..
As I said, and repeat... run it at the track, only then you, he, I and everyone else will see the facts.
Are you sure it is just a 331?.
