Mega BADASS small block.......
Impressive, but probably cost prohibitive for any practical use unless the factory get's behind it. Than you might see "bargain' prices around $25K.
Ford has been the only other viable PRODUCTION V8 Hemi in this country. GM did assemble a Hemi based on an Olds, engine, but never went anywhere with it, and, of course Aries has Hemi heads for Chevy big blocks that have been dragging racing for nearly 3 decades, now.
