Our local race tracks here in the Midwest, have gotten together to create a racing series that promises to be interesting and I thought I would help spread the word thru the Pontiac ranks.
It's run what you brung, just as long as it's got a Stock Block. I guess they're wanting to see just how far you can push a factory block car. Me too!
GM, Chrysler, Ford... Power adders or NA, bring it on! Should be interesting to see

You must be talking about those Ford and Chevy guys! We all know you can't hurt a Pontiac!

Just curious, does this mean GM Bow Tie, Ford Motorsports, and Mopar Direct Connection and other dealer marketed and sold blocks not allowed?

Good question but I don't know. I don't know what rules and cutoff's they've made. I was just asked to help spread the word about the series. There's a Facebook link in the add so I'd start there to find out.

My understanding is no, they are not.

The bow-tie block and SVO block a marginally better than stock when making power compared to a Dart, etc type aftermarket block.

I've ripped the mains out of a bow-tie block just like a stock Pontiac block, just like they split of out an SVO block in a buddies car.

My local track has a class that requires stock block, dual plane intake, and stock iron heads, 360ci limit. I was going to put together an engine using the 350p that came in my Ventura but they wrote the rules eliminating the Pontiac due to having a "air gap" intake after I inquired about running one. So the Ventura rots away in storage a while longer.

I dont know what it will end up being, but I gotta think there are going to be some very clear advantages hash out pretty quickly there. Some mfgs your just going to be able to do more with their stock block than others.

Perhaps it's time to think about building off of one of the '59-'60 389 blocks.

Thicker casting (with higher nickel content?) and reinforced pan rail, the bores start out very thick at .250 wall from what I've read.

Use your midplate to adapt the later BOP or Chevy trans and to mount the starter.

You and your buddy made mistakes somewhere in building the combinations.

Ronnie Crawford built Ford 347 SVO engine with D3 heads that would run 7.50s on boost every pass and the racers ran the things over 8500 rpm constantly. Stroke was 3.4"

So are we talking a large cubic inch Ford deal here? Just wondering.

Merry Christmas to you and yours, Clay. Hope the series works out well.

Dont sell us short lol . Properly prepped our blocks can handle some surprising power levels...even if only for a few seasons. Boosted apps especially turbo'd dont need max ci or extra high rpms that an NA app needs to make power.(yes if you can rpm more than your opponent you potentilly have advantage all else equal)

Well detailed block(no sharp edges anywhere), best you can do harmonic control, aluminum rods(shock absorbers), 3.75-4" stroke, no ragged edge tune-ups(stay on conservative side). Run a mid plate(put stress from chassis flex to bell flange,the strongest part of block vs stress thru block).

There's quote I can Ditto!

"Merry Christmas to you and yours, Clay. Hope the series works out well."
Thanks Tom, you too! Merry Christmas!

I've got to add tho, it's not my series, it's just interesting to me to see what guys can do with basic "stock" stuff. Before anyone bangs on me, I know, where do you draw the line on "stock"....everyone has their own opinions there! It's always impressed me with how fast a Pontiac can go with the basic stuff compared to other makes. I'm looking forward to running it some, but then again, maybe I'm biased! lol

Marty Pablekin went over 200 MPH with a stock 400 Pontiac block in a 1970 GTO. I think he may even of had factory iron heads but not sure about that part. Tom Vaught can tell you about it he is friends with Marty.

I'm waiting for the OEM iron block and OEM iron heads only class ....

I believe you are correct. When he went to E-heads he ET'd better but not mph... iirc! 3 full seasons over 1600 hp 7800 rpm! At end of 3rd season, tear down inspection found a crack had started in the mains.

vin63 has also been over 200 with a 406 a blower and nitro! Approx race weight 3000+ lbs!Trap rpm target was 9200! Ohio forged crank. Previous best was on alky(blown) with no body @ 2800 lbs went @ 197 with a cast N crank originally from his 69 GTO. That combo turned 8600 rpm. Blackened the crank when he switched to nitro. He used early 70's block.

That's called Stock Eliminator.
