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

The only thing I don't like is the 250 horse nitrous part. At that level the fuel system must be dedicated, the ignition needs alot of retart and the plugs need to be colder.
I install nitrous kits for alot the localls and only give them 100 horse and keep the other jets. At this level I have seen 1 second taken off the 1/4 miles times and it need no modifications to the fuel, the timing or the plugs. It is easy on parts and the first 100 horse increase seems to mean the most. A tank also lasts a long time.
Go to 250 horse and things will begin to happen/melt/burn holes.

NO ONES FORCING ANYONE TO USE THE FULL 250 SETTING /JETS on the KIT, in fact most of the guys use the 150-200hp jets but a 100 hp kit is not taking advantage of the way the engine can be made to run, and correctly set up its a very effective setup.
