reasonably priced engine combo

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 100-150 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
