    What would be the displacement of a small block that started at 350, got a stroke crank, and was bored 30 over? Or if it was 40 over? Yes, a 350 with a stroker is a 383, how about the 30 or 40 over?Thanks.

    A 350 motor with only a 3.75 crank would be a 377. A 350 with a 3.48 inch crank (stock) and .030 over is a 355. A 350 with a 3.75 inch crank and .060 over would be a 388.
