thanks for the correction. but you said 408" on both so......
a better comparison would be 408 mopar smallblock vs 408 chevy smallblock.

Or even a stroker LA vs. a Ford 400M at exactly the same bore and stroke. Of course that would negate my under/over hypothesis. IIRC 3 or 4 400Ms placed in the top 10 in the last engine masters challenge. One of them won it! I kept it Mopar only as this is a mopar site, lol.
