GTA's have those log manifolds, a really big restriction.

That's why the f-body engines were never rated the same as the Corvette engines.


Heads could be a determining factor as well.

I know the '128 vette heads do not flow as well as the iron L98 fbody heads, but I believe the '113 vette heads are much better on the flowbench.

If I recall, vette has a higher compression ratio too, although most of that is probably lost with the aluminum head.

What always got me was the axle ratios on the vettes.. 2.59, 3.07, and 3.54.. Fbody came in 3.08, 3.23, 3.42, and 3.73.

2.59 is absolutely useless.
