If it picks up 25hp, it should run in the 10.50-10.55 range.

Stock 340 A cars with the same gear as a 383 B body would eat that B body. 440 and Hemi cars, not so much.

my goal has been to get a 10.4x slip.
that would approach respectability with the cam and weight of the car, IMO.
hoping the vert adjustment does something to help too.
