Not Ranked
My question is not why 482 and not 427. It is why 427 and not 496? Or 525?
The 4.31 bore is as well supported (rings) as the the 4.25. It seems like it would be the same cost. Why give up 14 cubes?
Now the 525 is 4.31x4.5. The only problem is there aren't any inexpensive 4.5 cranks.
JE lists 4.25, 4.28 and 4.31 pistons for the 4.25 stroke/6.7 rod combination. Diamond doesn't list the 4.31 in the catalog. However, as Barry said, they have it available.
