farmall h stepped head pistons

lee oh · Aug 27, 2011

took the head off my h today to give a valve job and noticed it has stepped head pistons and a 3 3/8 bore. with a good valve job what power should this be making, was 22 before the valve job

ok just noticed that 3 3/8 is stock bore always thought they were 3 1/4

22 is low for stepped head pistons.
Be sure your timing and advance are working as designed. Also adjust the carb on the dyno under load. It should make 25+ Jim

i had hoped 22 was low. had everything adjusted perfect but the valves were pretty bad had almost a dead cylinder
