Very clean design especially under hood. I've never heard of a stroker 422. Never seen those wheels either. Sounds healthy and very lopey cam.
I don't know anymore about prices. $40k seems a little ambitious though.
422 is 60 over 340
I had a 422 W5 motor, X block that was 4.100 bore. Quite common actually. 416 = 30 over 4 inch crank, 422 = 60 over 4 inch crank
