For those who wonder or care, The long BB pump fits in the 67 B body no problem. With all the talk of the lack of clearance and the need for e-fans, I really wondered.

I picked up a good small journal 327 block and crank. It's missing the pistons and rods. I have a set of good large journal rods. My question is, are there special oversized bearings out there to adapt these rods to the smaller crank. If so has anyone tried this with good luck.
