I'm late to the party, but many moons ago I had a 383 race motor that the long block was prepared and built by MM. It was a monster of a 383.

8000 rpm shift points consistently and reliably. It had spent a few seasons in a bracket car prior to my ownership, and spent out its remaining years in my street/strip B body Fury.


I was very happy with the engine and how well it was balanced and assembled.
