Pipe dream motor swap: What would you bolt into your A-Body?

500" low deck hemi, splain that to me !

It's a hemi, built on a low deck block?

Before KB changed hands and got backed up on orders, you could order a B deck version. Not sure when/if those issues will be straightened out.

Then there's the Indy MAXX which can be either B or RB and wedge or hemi - but I've read there's casting issues that need to be fixed. New owners DSR may be working on fixing that, if so they'll be a good source.

But lately Muscle Motors has a block available, which is probably the best choice on the market at the moment.
