Bob,or Tom,what if anything can be done to address porosity with alu?I know its has been and maybe still is a problem,also does alu have more core shift problems than iron?NBD on a dry block but is on a water block.Tom

Thanks for helping Tom.
We are having made 20 crank shaft heat sinks and 20 valley pan heat sinks made to cool the block after pouring. We will pass a cooling water thru them to cool the pour. This thing will be like jellow for a long while after it is poured and we need to cool it fast. We will cut up many blocks as we did before to not guess as to what is happening, but know what is happening inside.

I bet it will be more than one of those classic $100 blocks, LOL.

Agree that the key for core shift and exclusions
is a proper pour with the correct cooling strategy. The porosity issue is more prevalent on the aluminum blocks as you mentioned Tom S but can be worked out with the right thought process. If the IA-2/Butler AL blocks are cast by the same source as before they should know how to do this having worked with AL in the past on other projects. Tom V. I will speak with our block guy to see if there are any other magic bullits out there too.

Tom and Gang, It will be casted by our casting house. And machined by a Roush Industries or one of their subcontractors.

I would definately go with an aluminum block over the $100 stock block. Why?? Because it's repairable. An explosion would not be nearly as expensive. I suppose if I were to put them in order of priority, it would be:
1. Aluminum Block 2. Stock Block 3. IA2 |

Oh I have seen aluminum V-8 blocks that have been un-repairable after an explosion.

Of course, in a street/strip application I would simply reverse #1 and #2. An aluminum block would be great for a street car, but only if money was no object. Of course we could say the same about a lot of things! |

I just wish the aluminum block was made with a higher deck height to get a better rod ratio with longer stroke cranks. Besides, this isn't a normal..... put it in most stock chassis cars anyway.
But something is better then nothing. Would Love to build a ATI Procharged 572 cu.in. Pontiac Street engine.

What great news!
It's really good to see the Butler family, with their stellar reputation and marketing prowess become involved with AllPontiac. Avoids a lot of duplication of effort and gets it to market much quicker and hopefully with fewer teething problems and maybe even a better price. Congrats!

Ok,I already have 2 pontiac alu blocks so I guess I can start this conversation off without too much trouble.
Why do the really high HP natural asperated engines like in Nascar and Prostock run iron blocks.I know the top fuel and funnycars run them for the expansion of running on the ragged edge of hydrolic in the cycs and easy repair.I have read that the iron block will make more HP than a alu block,all things being equal.If that is the case,except for weight,what is the advantage of alu?Tom |
