Bill Mitchell Products Introduces New Big-Block Aluminum Castings

Shannons engineering has had those on ebay for a few years
Not possible.
These aluminum blocks were redesigned and only started production in late 2019.
I bought a big bore (4.50) aluminum RB block for a 541 stroker. Modest power goals, 700 ft lbs torque across as flat and wide a RPM range as possible and let the horsepower fall where it will.
Going in a 70 V-code Roadrunner, and topped with a ModMan 6bbl.
Beep-Beep!
This is my actual block:thumbsup:
