Thanks for that info !
If this info is correct, looks like he gets 6 more hp, in GT/ auto trans, than you have in a '74 Vent. Don't know how NHRA gives the same engine a different hp factor, depending on which body it's in or whether there is a manual or auto trans behind it. But hey, you current racers know a LOT more about all that than me.

Assuming by the times he's running that he doesn't have an all-out Parsons & Meyers Super Stock 350. Or does he ? Just ASSUMING that he built the car, on purpose, to run a safe distance below his index, and maintain the rest of the car in near Stock Elim form. But, if this assumption is NOT correct, I'd like to have that info.
Just looked up some times run by the '74 GTO Stocker driven by Brad Koivisto. It ran some 11.20's.

So, a strong Stock legal '74 350 engine will provide enuff power to run under the GT index. Don't need a huge roller cam & alum intake. So, it makes perfect sense that a good 350 build, with a bigger than Stock legal, flat tappet or small roller cam should run under the GT index.
There are obviously 400, 428, & 455 engines which can also be built to run under their GT index. But, I figure the 350 will require a bit less traction, to hook it up. So, if building a low budget Pontiac powered GT car, the 350 seems like a good choice.
And, I've already mentioned the fact that some of the 400 powered Stockers have run SS, at a few races, & ran under their index. For example: The SS/IA index is 10.70. There are some of the 1st gen Bird Stockers, which will fit that class, which can run under that index, in Stock legal form.
Just all food for thought. If somebody wants to get into SS racing, but wants to do it on a lower budget than building or buying an all-out, big tire SS car, there are ways to do it, with Pontiac power.
