572" so the stroke is a little off. 3" mains is where it gets fun

So Chief will be using the CV-1 top end eventually? Just not on his new engine,which is identical to his old one,complete with standard port e-heads,and now in the car.

This is false,or what was relayed to me as bogus information.

Bet he can not wait to test the new CV top end. But also knows what he has in old reliable too.
If it does not make sense usually it is not true. And it makes sense to thoroughly test out the new stuff before it trusted. Has a lot riding on it.
You heads getting in the 7s with stock block was impressive, I said as much.
About time they did something E heads have not. Or did they ?
I just like yanking your Twin, don't get all bent.
Maybe you guys will be what keeps him from a 481X. Good thing right ?
Personally I would like to see him fight with a PMD style head, take it as far as can be taken. But that's just me.

... i'm not bent i assure you, i'm just trying to stop the misinformation from people that post things or even contact people with information that is not true ...

... Vaught contacting people and telling them Chief decided against using the CV-1's and i have actually sold off his top end was completely false, and you posting Chief has a new set of WP's when he does not is also completely false, but you still posted it, like i said just trying to clear up the misinformation ...

... actually the Butler's did have the CV-1's on their website at one time, listed with no pics, no price just "Please call for Details" and they never asked Roland for permission to do that either ...

... and i can assure you when i called them and asked about the CV-1, they certainly were not trying to sell me a set if you know what i mean, quite the opposite actually ...

Maybe they were testing the market to gauge the interest in a canted valve head?

Pontiac forums are filled with false/bogus info, just need to know who to believe or not and what Pontiac forums tend to be more honest vs not.
