It's an 11 to 1 motor.
They were very fast on the street in pure stock form with a 4 speed.

IF I were going to build a Pontiac Stocker, I'd go with one that came with a Q-jet. They just seem to provide plenty of gas for whatever engine you're running. Have run good on 301 Stockers on up to 428 powered 8 sec GT Super Stockers.

But, I reckin AFB's & 2-barrels have also won lots of races. The '66 GTO 335hp AFB engine has only a 300hp factor. So, maybe it would be more competitive than the Tri-Power engine, @ 60hp less. I'm assuming that the Tri-Power would NOT make 60 more hp.

Don't think I'm gonna try to hold my breath 'til somebody builds a 2-speed Pontiac Stocker, converted to 3-speed. If somebody did, it would be like you said about the 326. Would need a big hp factor reduction. For this, don't know what combo would be the best to build. Seems that the '66 Tri-Power GTO did the best of the 389 GTO's. Don't know how low the hp factor would have to be, to make it competitive. It's 360 now. Would need to be a lot lower than that.

Norman Warling & Bob Michael run pretty good with their '62 Tri-Power 389 Stockers. But their hp factor is only 275hp. Lotta difference in that & 360hp, for the '66 GTO.

I suppose that if I had to choose a 2-speed to 3-speed conversion Pontiac to build, without doing any more research, I'd choose the '68 Firebird 350HO. The hp factor is only 305hp, & it uses a Q-jet. And Adam Strang ran some 10.80's with his 4-speed 350HO, in E/S. Not the best Pontiac combo, but far from the worst.
