I'm considering an aluminum RB block for my Challenger.
From my searching so far, it seems that the options are:
- Keith Black
- Bill Mitchell
- Indy

It looks as though Dart does not make an aluminum Chrysler block.

From multiple postings here, and elsewhere, KB makes a very nice part, but the odds of actually getting one are long, and indications are that he may not make it in business much longer.

Keeping in mind that it is internet complaining, there still seem to be a lot of negative reports on Bill Mitchell, both from Mopar and Chevy people.

I've dealt with Indy before, and understand some of the service issues, but I'm assuming they make a good block. They have that reputation.
Is the Indy block a race only piece? This will be going in a Pro-Touring car. I have read that the block only comes in a Hemi mount configuration.

Are these the only options, and are any of them any good?
