Quote: Great motor, same bore and stroke as a 426 hemi or stage III Maxie, what could be wrong with that?
You lost me here. If the bore and stroke are the same would you not have a 426 or are you getting a difference in cubes from the piston size?
Yes. He's correct. 426 would be at a stock 383/426 bore of 4.25" and 3.75" stroke. Typically, a .030 overbore yeilds 432. A .060 overbore would be 438.
