Positive news of new Mopar blocks for sure. up

The choice of an (Indy) $6,500 aluminum block and almost $5k for a (Callies) cast iron block, has me leaning toward aluminum.
I wish I still had my aluminum KB block from 2014. But it was sold with the car "turnkey".

I have a nice set of B1 original heads that could use a nice 4.500" aluminum block . . .
