Locomotion:

I just found that the 1998 catalog, page 25, lists KB flattops as "Service Pistons for the MP 360 Commando Crate Motors, 9.0:1." It doesn't differentiate between the 300hp or 360hp versions. Perhaps they were early KB 107's. The notches are not like the 2 "eyebrow" current versions, but they would likely provide about 9.0:1 if the heads and/or block were not milled a lot, just cleaned up.

P5249478 - 4.020"
P5249470 - 4.030"
