Ryan's Small Block Engine Dyno's
I post this link every few yrs. It is getting a little dated now but still a good reference source.

109 combinations and yet you can count on one hand those with listed max horsepower over 6000 rpms. Makes me wonder if all the folks with 10 grand tachs are overly optimistic?

When I was in high school, a friend of mine installed an atermarket tach in his GTO, and was all exited to show me how his engine would rev to over 10,000 rpm. The knucklehead had it set on 4 cylinder mode!!!!!
Even after I told him about it, he decided to leave it that way, 'cuz he thought it was cool!!!!

That is a great resource I have linked many times. The biggest problem I see in using it is the fact that the majority of corvettes come with a 3.08 rear gear that is about useless with the high HP combinations. Many first timers want the big power numbers without taking into cosideration that the gearing in their car will not match up well to the engine power band. This is a common rookie mistake and many spend the big bucks on the high horsepower and are disappointed in the performance and streetability once it is in the car.

I don't think there was one engine that had it's torque peak below 3500 rpm. I have a 3.07 diff, and I'm installing a 700r4 tranny to crutch the diff ratio, but with the wide gear spacing, you still need a broad torque curve. It's all about trade-offs, I guess.

It's all about matching the right pieces to find balance - especially in a C3. Not just the gears, but the overall use of the engine...and matching it with ensuring the chassis, suspension, brakes and tires are up to the challenge of newfound power...making sure it's "fit for purpose" - matched to how the car will be used.
