The thought was an aluminum block would save weight on the nose along with aftermarket strength compared to a stock block. After reading some of the posts I need to do more homework for sure!

Thanks,

As close to Butler and AllPontiac as you are, I'd give them both a call and see what they recommend.

Thanks David. ;( Wham.

What I don't count. LOL.

Hope you have better luck than I did in actually getting an aluminum IA block. About a year ago, I had cash in hand and couldnt buy one. And they couldnt even tell me when they would be available. No slam here....just the facts.

[David Holmberg]

I was referring to the blocks, Aluminum Vs Iron... Horses mouth, so to speak...


As for who builds it, that's up to him. But Ken's Speed and Machine in Brooksville Florida, Home of the Worlds fastest Black 76, stock suspension, Drag radials with Power windows, Trans Am, is as good as any builder out there!

Better?

But for long term throw anything to it live forever. I would use the Iron IA II block and live with the nose weight. There are things you can get away with to make a front heavy car hook. Just ask those SS and stock racers. And some illegal stuff too. LOL.

i agree with dude, use a iron IA2 and save the money difference to spend on some tiger heads and you will have a problem NOT making a least 950hp; if you choose your builder and components wisely.

We are going to offer a totally redesinged Aluminum IA II Block for sale around the first of the year. We sold out the first 50 aluminum blocks and converted the tooling back to cast iron. Now we are making tooling just for the aluminum blocks. We are using a foundry that makes the Donovan Aluminum block. They are if one of the best aluminum blocks out there for the Chevy motors. We will have a killer piece.

As for how the other Aluminum blocks are holding up. Ask Jeff Verdi what he will sell his for. And what he thinks.

We Proudly Stand behind our products.

Thanks to all for the responses.

Bob, can you provide a estimated cost and max bore size of the revised block?

Mine is not for sale,unless you got some really deep pockets,and want to make me happy.....wait a minute,that didn't sound right.

Seriously,I love my Aluminum block and I have won over $7k since putting it in the car.That plus the Championship,means that I will have won over $10k this season with it and the season ain't over yet.
My future plans include building another 525 with one of the new aluminum blocks coming out and putting it in the GTO with a powerglide.Install some 380cfm heads and really get some low ets.
All I need is a few sponsors$$$$$$$$$$$$$$$$$$$$$

Hi Robert,

Will the redesinged blocks be capable of handling high horsepower or will it be a street block like it's predecessor?
Can you give any details of the improvements?

Thanks, Todd

Street block?
Guess you never heard of Jeff V.

They're out there, but you'll have to do your own warrantee research. I'm more interested in my hobby which is working on our vintage Pontiacs.

Constant posting on PY to jack up my post tally does not interest me at all.

IMHO.

seen that someone was asking about larry coopers motor, he broke a rod was not the blocks fault he has since got it back together but it did take a new block,it was damaged by the rod beating on both sides at 7k rpm. but it was not a problem with the block.

You think maybe the car standing on its bumper might have had something to do with the connecting rod failing (due to lack of oil, maybe?) Naw, that could never happen.

Course the block never takes any stress when it is tied into the chassis and you drop the chassis from 13 feet up either, right?

Jeff V. seems very pleased with his aluminum block from allpontiac but the consensus seems to lean toward iron. Still not sure what to do. Found a couple of cars on Butler's site running the aluminum but still not very many racers elect to go that route. Spoke with a few engine builders and they too have mixed messages.

Dwight

[Tom Vaught]

Aluminum will never have the overall life of cast-iron or the number of rebuilds available due to needing sleeves in the block and the metal composition/strength. Weight is an advantage but at what cost?

im just saying the mains did not pull out of the block as rumored a rod broke for what ever reason, granted the wheelstand sure didnt help.

No they're not. Nobody warranties any part that is specifically to be used in racing. Yes, there are vendors that will stand behind their product when a manufacturing defect arrises, and then there are those that tell their customers to pound sand.

Maybe you are confusing the other block manufacture's block with the IA-2 company's blocks. The other guys did have main cap bulkheads breaking loose on their blocks. Without a score card it is hard sometimes to keep the rumors straight.

[Brian Baker]

You mean "keep the facts straight", right Tom? What happened to Brad's block was not a rumor.

[Tom Vaught]

Actually Brian, I thought it was Brad's Dad's block, his step mom's block, AND Brad's block that were in bad shape.
