sbc horsepower?
 

How much horsepower can I expect from a built for stock 327 275 hp ...I have Carter and Rochester Quadrajets which would be best to use...are crank scrapers legal?

Re: sbc horsepower?
 

380 HP.....Q-Jet......Scrapers are legal.

Re: sbc horsepower?
 

Im just guessing here I would say 420 is easily do able even on a soft dyno if you have all your ducks lined up.Thats saying you are making 1.28 per cubi inch i have no calculator :)

Re: sbc horsepower?
 

Good thing we don't race dynos......I have 2 customers that make a little over 380 and both qualified very easy at INDY.

Re: sbc horsepower?
 

Wow are dyno is 50 horse down from WJ's my 283 makes 350 easy and guarantee i would made Indy ..I thing Wade Owens makes way more than that maybe get your dyno calibrated..

Re: sbc horsepower?
 

I guess WJ needs to get his dyno calibrated too...lol It doesn't really matter what a motor makes on a dyno, its how fast it runs. Always use the same dyno when testing and try to improve on what you have. After all, its the improvements that make you faster.

dyno, racetrack, dyno, racetrack, dyno, etc, etc, ect,.....

thanks for yor imput guys...is the Carter Quadrajet of no use as race carb??

Re: sbc horsepower?
 

What he said! LOL!
Until you know what the number means at the track, the number does not tell you much.

Re: sbc horsepower?
 

Well the guy was wanting horsepower numbers mine are real no use in arguing with you.A real dyno a 327 should make 420 I know Jims 283 pb make 370 .

Re: sbc horsepower?
 

Never tried the Carter.

Calm down Tommy :)

My 283 shows a lot higher than that on the dyno we use. I bet Wade's shows lower numbers and it still eats my lunch in the hp department. Go figure.

I dont get wound up do I lolll :)

Re: sbc horsepower?
 

I bet mine is probably the lowest of them all. lol

Re: sbc horsepower?
 

I think I could fix you up if you wanna dump some coin??

Re: sbc horsepower?
 

The info you stated about using the same dyno is really true, and knowing what YOUR numbers mean on the time slip will always rule the day.

I've built a number of these motors and the one I just finished makes 415 w/ break-in oil. It will be going in a 67 Chevy II so when it's done maybe we can compare sheets & slips?

Re: sbc horsepower?
 

Sounds good to me ,but i have just about dumped out.lol. You got a pay as you race plan ? lol again.

Re: sbc horsepower?
