MMX has 6.4 BGE blocks in stock

They aren't even all that bad on price ,especially if you want to do a stroker 6.4,and you're replacing the complete bottom end of the engine anyways.

My buddy has a 461 aluminium block in his 09 Superbee. It's an earlier block,and Arrington built and installed it about 12 years ago.He's actually put about 50,000 miles and a pile of dragstrip passes on it,and it's still going strong

I dunno what to think about this; one of the attractions (to me anyway) of the hemi is that's its an iron block capable of tons of abuse.

If you look at GM for example, they have essentially the same engine in aluminum and iron but only their heavy duty trucks get the iron blocks, their cars and passenger trucks get the aluminum ones.

Dart has their hemi blocks out now,with the capability of close to 500 cubes.

Depends on what your looking into do with the engine. This isn't something you drop in for a standard replacement of what's under the hood, your spending $$ to have the block machined and bored to your specs most likely for a racing application.
The aluminum block saves weight over cast iron, if shaves a 0.1 of a second off your time that could be the difference between winning and loosing. The less weight also can contribute to a better weight balance of the vehicle (front to rear), again your paying for the advantage.
Aluminum will also reject heat better than cast iron. The cast iron will tolerate overheating better than aluminum, that probably the biggest driving factor why it's used in heavy trucks.

Yeah exactly, that's what I said; for car duty alum might work OK, but the point of a truck is to work it, thus the iron block makes more sense for us. In theory aluminum sheds heat quicker, but in practice we know the iron block is the better choice for a heavy duty cycle. Heat is more a function of the cooling system rather than the block material, my truck tows at the same oil temps it used to run empty on, all by just throwing in a 180 tstat and chopping out the silly AGS. If you're towing up a long grade (say the IKE), both alum and iron are going to hit the same oil temps with the same cooling system in place, but the iron block will always handle it better. So you're going to need a robust cooling system regardless of block material, you can't get away from that just because you're using an aluminum block.

My buddy is running his Superbee tonight,and he's running 11.7's tonight with the DA at 3200 ft. Which is on par for what the car normally runs.
