ok, another carb question

I have a 327. I don't know all of the engine specs yet but here's a general idea...

I have a Holley 750 List #4779-3. From inet...(750 CFM, Stock jetting F-70, R-73, Power valve, 6.5 #4150) None of this means anything to me other than the 750.

And, a Mopar (Holley) 600 CFM model 4160. List #4749-3

So, from what I know of the motor,

Bored 30 or 40, flat top pistons, 2680 (forged small journal 3.25 stroke) unk cam, and Edelbrock Performer RPM intake.

So, with that limited info, would anyone be able to tell me a rough idea of what horse pwr I could expect and/or hope for without going broke, and which carb would work best?

Thanks much, I've become obsessed with this site and have learned more in the past few weeks than many years before.

750 is way too much carb for a 327 IMHO.

Re: ok, another carb question

I agree, 750 is overkill.

Your cam is the deciding factor on how much hp it's putting out. If it's stock, then you've got around 275 horses. If it sounds 'lumpy', you've got more.

Headers and a little larger than stock cam will wake it right up.
