Bill Mitchell Products Introduces New Big-Block Aluminum Castings

Ok, so I looked up Shannon's and yes, they have Mopar type Hemi and Wedge aluminum blocks. $11k?? "make offer"?
I wasn't aware of that, but still, the articles in 2019 announcing the BMP blocks state they are a redesign.
I'll ask Bill Mitchell this coming week and follow up.

A guy I know turned up with a kieth black alum. wedge block at the race track this past year , gues they`ve had them and hemi`s all along .
