Hey Warpspeed-----If you changed the Bore to 4.130" and the stroke to 3.335" how much effect would that have on an open engine say at Charlotte ?

It would typically lose power everywhere.
There is a measurable power difference between 4.175 and 4.185 bore size, even with ci remaining the same.

The 4.185 having more power?
