@Dale Davies “Cubic money supplies ” LMAO!
How true! Also agree on how the cube inches are made are good for one arena vs another. Like the 355 CID rule. NASCAR engines displacing the same size CID differently for the track to be raced. What they use at Watkins Glenn is very different from a super speedway.

The problem is how long is a piece of string? Same with bore size. A “small” bore is ASScar is 4.155 and the rules on bore size (last time I checked) was 4.185 maximum because the GM junk can’t go bigger and the Chrysler can. In that case, the 4.200 bore (maybe 4.220 if the block sonic tested good enough) gave the Chrysler an “unfair” advantage.

Any decent engine is over square. Bore to stroke ratio matters.

This isn’t directed at you Rumble. Just trying to consolidate everything in one post and you posted last so I grabbed yours.
