I have a BMS 3.55 crank that I can sell. Its a narrow journal cut 60/10. Its was in my 4.1 years ago. Ran it for 2 years with no problems. If anyone is interested, pm me for a price. I can also sell it with J&E pistons and BBC rods machined to fit a 4.1 with a 4.00 bore. Will let it go cheap.
Bob has not gotten anything Buick V6 in in years, also they are going out of business, all they have left are a few short stroke Indy cranks & some old worn out heads.
