I'm the first to admit I don't know this engine,... but as in any engine we know it must turn, either in the piston or the conn rod, and maybe both. And whichever it is, it must have space for oil, or it could gall. There is no standard in automotive engines. Back in early years, 60-70, ford used the "both" method, meaning the pin was a push fit in both the piston and the con rod,....using clips in the piston to retain the wrist pin. SB Chev on the other hand, chose to use a press fit in the conn rod, letting the wrist pin float freely in the piston,.....using NO clips in the piston whatsoever. Both methods worked well,......except the ford method was very critical in getting a good close fit in the conn rod. In those days a tap fit was considered not enough clearance for oil to get to the surface that must be free to rotate (rock).
