Which can handle the heat better. And why.
Standard or thicker?

Not being a m.a.
Have my own theories.
Just picking an experts brain

BTY, if i was going to buy a crankshaft to go fast, it would be a 4" with 3" mains.

I personally see the IA 2 block with a 4.350/4.375 bore and a 4.500 stroke as the best all round Pontiac combo right now. N/A or Power adder.

The easist is the 4.350 bore with a 4.250 stroke for people not wanting to get into heavily modified heads, etc to make the 535 work efficiently. Ya can twist that combo (505) 7200 and not break a sweat.

If I was road racing I would use the 4" crank and a 4.350 bore. Better off the corner deal. I have built a few road race combos. All 428 style. All run great. t would run 7000 no problem. But I would get into some serious internal components.

It would be a 476 cu.in. BBC style combo and build along those lines. Just need a good flowing head with great mid numbers and the right camshaft choice.

I don't have any info on the durability of the aluminum block. I think the Jury is still out on that deal and long term heavy duty useage.

You would need more gear. And I don't think a tremec will hold up.
