Found a deal on a new 4 and 3/8" stroke RB crank with 2.20 rod journals. Didn't buy it yet but am thinking about it.

Everyone's been talking about 4.25/2.2 having lots of oil pickup boss clearance for awhile now...I'm thinking the
4 and 3/8 arm is only another 1/8", and would only amount to 1/16" closer to the pickup boss.

Do you guys think I could get away with the internal pickup with that crank?
