Muscle Motors, Michigan - Talked to Eric Budden there. Seems nice, got a good price on the rotating assembly. Research shows they went under 2 years ago. Is that true? The website is still up.
They only sell parts now. No longer do machining or assembly.
Right at your 250 miles is Bischoff Engine Services (BES) in Indiana - Tony Bischoff knows how to make hp on any motor. He ended up fixing my "the block" that MM totally screwed up. Street/Strip 505 with OOTB TrickFlow 270 heads made 713 HP and 707 torque with a Dwayne Porter spec'd cam.
I can't say enough good things about BES. They are my type of machine shop and I am very difficult to please. Not the cheapest though.....
