Journal size JDB pullers put on cranks?

elkcagg · Dec 1, 2013

Just wondering what size journals most people are putting on JDB cranks. Is 3" too big? I have a set of welded rods I'd sell very reasonable that have the 3020/4020 journal welded to an A rod but the CTC is 12"?. Maybe these would work in a B setup but if no here would be interested in them no sense in me putting them on the classifieds. The guy I bought these from was going to put this in a A with 8-3/4" stroked crank & use MW style pistons. The rod to stroke ratio is not good in my opinion for any A. Otherwise I'll hang them on the wall or scrap them. Thanks

what is the correct rod to stroke ratio ?

2.25-2.75 is common.

From what I've researched 1:6 ratio is about the lowest I'd go on a 2 cylinder.
