My first time posting but I have been reading a lot of old posts and I must say there's a lot of very intelligent people on here.
I have a JD 60 that I'm gonna build over winter just for pulling (tired of getting beat by them olivers). My question is, has anyone ever used the block and head from a 630 along with a 9" crank? I was just brainstorming this the other day and thought that the 630 head would be a better candidate for running higher compression.
Also anyone know how far you bore a 630 block? Can it be sleaved to 6 or 6.250? T.I.A.
