If you make it stock legal you can always run it as a bracket car. I don't think they allow Corvettes in SS/GT classes.---Trevor

I've owned a few TPI cars. They make great street engines but not good drag engines at all. The intake design is great for low rpm torque and horrible for high rpm power. Running in stock you'd be stuck with the TPI manifold. Even with a huge cam good luck getting it to sing over 6k. That would crutch your gearing really bad. Ask around to see if anyone successfully runs TPI engines in Stock.

That is correct......The Intake is really a restriction according
to my engine builder although there are a few quick Corvette
around but not sure of exact year.

The weight break is just under 10.5, so it can run D, E, and F.

The factor is high at 300, in E it needs to weigh 3170#, and run 10.80. That's tough.

Yes, there are some TPI cars that are fairly quick, and successful.
