Now for the non-turbo 301 Stockers.

I assume that you will also need both the turbo crank & block.

The '79 Lemans that Billy Nees has is the only serious non-turbo 301 powered Stocker I've ever heard of.

He's shared info about it before. Don't know if he'd be willing to share any of what he's learned, here, or not.

I do remember him saying that he & Don went thru quite a few cams before they got one that worked good. And he said those 301T blocks & cranks are getting real scarce.

Any non turbo 301 drag racing info that anyone can share would be appreciated.

I do my own stuff with help from Dwayne Porter at Porter Racing Heads,Dale Spooner at Motion Machine in Danville Virginia and Joe Woodward. Been doing most everything myself since I was a teenager and I'm not going to change now.

That would be a mild understatement!

Maybe Billy can help with this one.

Are there any 350 or larger 2-barrel Pontiac combos that might be competitive, or at least might not be too hard to make run under the index ?

I don't personally know of any 2-barrel Pontiac Stockers.

I'll look up some specs for some 2-barrel Pontiac engines & see what turns up.

Wow ! Apparently VERY few have ever tried to run a Pontiac 2-barrel engine. For the early years they were just rated whatever Pontiac had 'em rated. The only factors I see that were changed were for the '73 & '74 350. It changed to 210hp, in 2002. Maybe somebody tried this combo & asked for a reduction, & got it. From what I see, those are the only years you'd have a chance. The factors for the early 350's were more than for a '77 400 4-barrel engine, at 265hp. And the 400 2-barrel factors were even higher, at 290hp. Those 290hp engines only came in big cars.

There was a 255hp 400 that came in '67 GTO's.

So, what about it guys ? Could you get a '73-'74 2-barrel 350 under the index, at 210hp ? I don't know how much power you can get with those little 2 barrel carbs. Would like to get some input from some of you GM 2-barrel racers.

For a 350 and larger combo, the only decent one would be this one. It's not without it's "issues" though. It doesn't have a whole bunch of compression and it's the only one of the GM 350s that uses a 2G carb with a 1.18 venturi (same carb as a 305). All of the others have at least the 1.25 venturi 2G.
But ya know, for some reason when ya look at the specs and the pieces that go into a Pontiac, they always seem to run better than they should.
Oh BTW, as far as I know, all 301 cranks are the same.

"...as far as I know, all 301 cranks are the same."

Have never seen a 301 crank. Just going by what I've read online.

Here's what I usually read about the 301T crank.

"...a rolled fillet crankshaft..."

Don't know what that means nor if the T crank is actually different from the non-T crank, or not.

Another article describes the turbo crank this way.

"...installed a sturdier crank with pressure-treated fillets..."

Just got some new info. As said, I've never before seen or heard of any 2-barrel Pontiac Stockers.

But, an eyewitness says that he remembers that Don Himes used to run a Pontiac Lemans wagon, with a 2-barrel. Said he don't remember it being a high qualifier, but quick enuff to compete. This was before Don had the GP.

I'll just take a guess that it was a '73 wagon with the 350 2-barrel. And, may have been the car that got NHRA to lower the hp factor. But, it could have had a 400 2-barrel.

Anybody else remember this car ?

Don't have any pics of it. But i did find a nice pic of a '73 wagon with a GTO front on it.

Yes he did , but it was during the 70's pure stock era. He used to drive it around in NJ. About the same time as the Marvosh car. Before he had the white 72 wagon Stocker..
