do you have a manual transmission ?
and what is your rear gear in your Corvette?
I build engines all the time, and I can give you a list of parts to build a combination will work correctly, but you will need to match, the intake and carb, rear gearing, transmission stall speed if your running an automatic,(3000rpm in this case) and the correct header size to that engine to get it to run correctly. With today's better cylinder heads, and cams, it's fairly easy to build a high horsepower engine, provided, you take the time to do your homework and match the parts to the intended use, airflow, and the cars usable rpm range due to its gearing.
The two biggest mistakes I see made constantly, is not matching all the parts to the rpm range in which the engine will be used, and changing the combo midstream due to the super deal that you just got on some part, I'd say 80% and 90% of the engines I see have mis-matched parts, and when you really get down to
ask them, they got us super deal somewhere on the cylinder heads, intake, cam and kit, or some other major part that does not match the rest of their, combo or the cars gearing.
For example
here's a combo that works
but you should have 4.11-4.56 rear gear's
your Corvette must have a manual transmission(or 3000rpm stall converter)
11:1 .compression 383 short block
iron eagles to 215 C. C. heads (pocket ported with a three angle valve job)
a crane #114681 solid lifter cam shaft
and EDELBROCK rpm airgap intake
a 750 CFM vacuum secondary carburetor
full-length 1 3/4-inch headers with a three-inch exhaust and low restriction mufflers
a 7 QT baffled oil pan with a MILODON windidge screen
a 250 hp nitrous plate system under the carb
I put this combo into late sixties and early seventies Corvette's and Camaros all the time, if you have the correct manual transmission and rear gear you're looking for a fun car that will run deep in the 12 second range,(without the nitrous) with the correct suspension and slicks, and will still work well with the nitrous which by the way works exceptionally well with this, combo But it would be an absolute disaster to stick that engine in a Corvette with the late model TPI intake, and 2.57 rear gear's. And NO it won't pass emissions testing, and yes it makes well over 400 horsepower and if your any good at parts shopping it makes for a relatively inexpensive, engine combo

I have a manual transmission and a 3.36 in the rear. But I could easily change the rear to something in the 4.11 range. That wouldn't be a big deal. And would my 750 CFM QJet be enough carb for that? I don't have headers, but with an engine like that, I would obviously use them.
I see what you mean though. Thanks for the information! I would really like to get seriously into engine building. It is a great thing.
Thanks again!
