What are those heads worth?

GIZMO you run SS dont you?You should get the heads,then tony can get the block and I can get rid of my crank and pistons

No, he runs Stock Eliminator. Much stricter. I'm sure he'd have an idea on what those heads are worth though. Maybe someone will bite on them.

That is a pretty good price for those heads. Heads-Up is one of the best shops in the country for Class heads. I am pretty sure that the block is a regular Bowtie block not the LTX version. For Super Stock it would be 4.067" (4.070" is max.). Doesn't Ed Wright runs one in his car too?

For anyone looking at that add, the Allisons always have top notch stuff. You are looking at a combination that would most likely run mid nines in SS/IA.

If I had the money I would but it and part it out for the block!

I've talked to Dave at Heads Up a few times. That's where I'll get my heads done when the time comes since they're 20 minutes up the road ! Like Gizmo said, he's a very busy popular guy.

Re-read post #24 guys. It most likely isn't an LTX Raceshop block. Probably the same setup that Ed Wright runs. He runs a regular sbc block with LTx heads on it. That is allowed in Super Stock.

I called and asked him if it was an actual LT1 bowtie block. He said "yes it came from GM with only 25 made. Has the screw in freeze plugs and was bought through Bob Cross at GM."

Did you see my post in your Happy BD thread?

What is the bore size? 4.125 would not be legal for Super Stock. Maybe they made some small bore blocks?

I think someone said 4.067" That would leave plenty of meat and should be some good ring seal with bores that thick left.

They come with a small bore size and you can end up with a max of 4.125 if I remember correctly.

Indeed! I wonder why Brady hasnt posted pics of it?

Ed Wright

Sounds like my stuff. Except mine is .070" over this time. Those are great heads for the rules we have to use. Not like real ported heads.
Do you know his name? I may know him.
You do know you have to modify LTX heads to use on that block , right? It's not reverse cooled. Heads Up! Cylinder heads does that to SS LT1 heads.

Btw, we are now allowed .080" over. It will go 4.125" with no problems.

Dammit someone needs to convince GM to sell their machinery for those blocks.

The things I would do for a 4.125 bore LT block...

I've never seen one so this is speculation, but I would think it would go to 4.185" with no problems. (400 sbc bore plus .060" over) I wonder what affect the siamese bore would have on cooling as far as the LT1's ability to run higher compression than typical sbc's due to their superior reverse flow system?
