The 1970 350/370 (Holley) Corvette stick only is factored at 355 for GT with factory heads. That's 2840 in GT/A not counting the driver @ 170 pounds. Shipping weight for a 66 Chevy II 2dr sedan, depending on the V8 combination, is 2825, for a 67 Chevy II 2dr sedan, it's 2800.

However, for some reason, the 1970 350/360 (Holley) is rated at 325 that's 2600 in GT/A (not counting 170 pounds for the driver and I'm not sure you can get there, or if it is legal), and the 350/350 (QuadraJet) is rated at 370 (that's 2960 in GT/A not counting 170 pound for the driver). All those are for factory heads, add 5HP for aftermarket heads if you need them.

If you're looking at a 1970 Chevy HP 350 with a Holley, I think the 350/370 stick only Corvette is what fits your car. The 1969 version is factored at 400 for GT, you don't want that.

It looks like the engine with the most closely matches what you're describing, and that fits your car, is the 1970 Corvette stick only 350/370. How fast it is, I don't know. I think your best bet is to contact Nitro Joe, and see if he has the information you want, and send him some money.
