Thanx for all the info guys. I'm really a happy camper now. I knew the rods were different with the bigger pin but never would have thought that the cranks were interchangable. I had already planned on milling the deck surface to raise compression and I have a 848 head that I'm putting on.
SECOND QUESTION: What is the compressed thickness of a typical 261 head gasket? I want to bring the piston to zero deck but don't want it too close to the head. Or should I not worry about blueprinting it this much and just take off .020"-.030"? .040"?
