Re: 8BA crank in 59AB?
Easy swap. I put a 51 Merc crank in my 59A block. Just buy bearings for the 59A block. The first and secomd mains ar the same for both blocks. Just the rear main need to be 59A. I used the 8BA rods because of the easier cheaper bearings. I have an extra upper rear seal holder if you need it.
