I’ve just installed a 3:55 gear set in my 46 1/2 ton. It has a 235 in it. I still have to replace the okie bushing but I’ll let you know how it works when I’m done. I am also wanting a bit higher highway speed.
1946 Chevy 1/2 ton "patina" pickup with a 1953 235 engine, otherwise all stock and unmolested!
