Are all blocks for Gen IIIs iron? Is there an aluminum version at all? Just curious. Was thinking about future projects that may use a G3 Hemi.

The old 6.1 style aluminum Gen 3 blocks that was designed and cast by Arrow Racing are sold out from PREFIX. We have one of the last blocks as the 73 Challenger build's 426 engine. There may be some available at Summit or Jegs? Mopar has a 6.4 aluminum block P5160138 which is cast by TEI that we saw at SEMA 2018 and also there is Gen 3 Perfomance H3MI 357 aluminum alloy block, maybe a few billet options out there that are available but at much higher price. Rylis knows! Much better and more informed answer than I could give.

Josh could probably answer this better than most. He bought and sold one or two before he settled on the one he used for his build. Pretty sure it’s a high horsepower block. His build is listed here somewhere
1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27

There are four new part numbers for aluminum blocks, 2 6.4 and 2 7.0. P5160143 through -146. They're in the latest MP catalog, but still vaporware. No one has any in stock and no one seems to know anything about them.

I believe KB is going to produce a Gen 111 block for the public. Not sure what the difference would be in their aluminum block but likely will have many modifications to make big horse power without block problems.
