Tim I can't say for sure.... In my excitement to finally get the engine back last week I had not noticed the extra length of the oil pump. I can say we had only the block and crank shaft to start with. Rebuilt my old Carter carb. Got a head from KW and between KW and a local vendor ordered everything else new including the oil pump.
I am having front brake drums turned at the same machine shop and will get the info on that when I pick those up later today.
