I have a line on 2 - 360 blocks, a 72 and a 73 both unmolested. Considering using either one for a 408 stroker. The guy had both blocks sonic tested, see attached. Which one would be the best choice, most likely will go .030 over? Mostly street driven and a few possibly a few passes.

Thanks

I would repost this in the Race forum where the guys in the know are more likely to see it.

The 1972 is the better block. Major is thicker. That block will work well.
