Exact sales figures aren't available but it's encouraging to me that a moderate number of the solid blocks are out in the world now. It provides a lower cost alternative to billet and we've proven that it can handle 3000-ish horsepower in an alcohol or nitro application.

Hats off to AP for providing options for the Pontiac world!

And then there's stan....

Steve,
Would you happen to know the difference in weight between the Solid aluminum IA2 block and your billet block?

No, I’ve never even seen my billet block in person yet. But I can tell by the photos that it’s quite a bit heavier. I believe the solid IA2 is 40lbs heavier than the water version.

Steve,
Thanks. Based 40 lbs difference and water at 8.34 lbs gallon and using 2.7 as the Specific gravity of aluminum, That would have the water block holding about 7 quarts of water. Does any one know how much water the block does holds?

That’s my son in the first pic. He built that whole car in 4.5 months. Tubing, tig welding, tin work, carbon, lexan. Everything but paint. I’m very proud of him.

Nice looking 1968 Firebird, congrats to you and your son!

Here is the weight of the IA 2 A solid block if that helps with your calculations.

Do you know if Dave has made any of his billet RV heads water cooled. He told me he could mill out some cooling pockets and place a piece of heavy aluminum plate over, weld up and machine. Then drill some holes in the right spots.
I know in your case you have the solid blocks so its not about your heads.

How much power does Ryan's big inch twin turbo 481X have vs Justins little 488 with E heads and twin turbos ?

He’s working on a set right now.

You do know that Tommy’s car is putting out way more hp then Justin’s car.

That statement probable is true on a chassis dyno. But they are both showing just about the same HP at the track.

Yes , I know. What does that have to do with my question ?
Tommy's car is great. But its a Pontiac block with BBCish heads on it. Not my cup of tea.
RAIV and RAV heads are, even if there is no pushrod in the port.
To me, Daves heads are something that would have happened in PMD if Pontiac had been allowed to compete with Chevy and not gotten screwed over tying our hands behind our backs so to speak. Had PMD been going balls out from 1970 to 1990 a lot of things would be different.
The stuff that die hard Pontiac fans are doing on their own dime is nothing more than what could have been done by PMD.
We are crazy but cooler than everyone else.

[slowbird]

If PMD kept developing race related parts they would've ended up at a Warp6 style head. I highly doubt they would've persuade the RA5 head very far at all. Just like Ford didn't.

[Stan Weiss]

They were looking at 3 valve designs.

In the mid 60s.
The 1970 SOHC Hemi prototype was another direction. The 73-74 455 SDengines are actually what was left of PMDs attempt to build a LS6 street killer 10-1 455. Dan had his hands a one of 2 sets of #96 casting 455 heads. 10-1, same ports as the 73-74 heads down to the pushrod tubes. RAIV valvetrain with 4 bolt block, forged rods and pistons. around 90cc.
Chevy stopped it and other programs because the Vett had to be the fastest GM car.
The Opal GTs were a Pontiac car. The bulge in the hood was from the inline 6 they had. Had plans for a T ram 2x4 428 with RAV heads and forged crank.
Pontiac had big ideas for performance. We are keeping up with the tradition.

Ford got rid of it when a Chevy guy got hired to run Ford. Fired the tunnel port guys and hired a few of his engineers and made a better BBC, the BBF.
If the RAV program was not squashed I do nt see why they could not have went the way Dave is right now.
That head still has Pontiac valve cover, RAV ex and cam, inline. Its pretty close to a Pontiac head in a lot of ways.
It will be awesome to see how far it can be pushed.

Why would you compare Justins Jurassic headed car with one of the quickest, if not the quickest no prep car......Tommy’s would be a much better comparison with his better Pontiac headed car!

They are only close in ET because Tommy’s car/combo only has a few passes on it, give him a year or so!

Your number 2 till your faster than number one George. It's that simple. What could and should be have not happened. Tommy's car is a work of art with all the current technology. It got wrecked like many do trying to get to the front. May get wrecked again on that journey. Smart persistent people like Langer for instance keep going and accept seatbacks for what they are. I think Tommy's group has the same attitude. He will be very fast at some point just not today
