Whats the deal with the pistons? Thats normal to have the pin pushed up in to the oil ring on 331/347 stuff. In fact, I dont think you can get it any other way. The 347 uses a 3.4 crank and most likely a 5.400 rod. That leaves you with a 1.100 compression height. They have them listed at 1.090. (.010 in the hole) If you tried a 5.090 rod that would need a 1.41ch piston, but I think the bottoms of the pistons would hit counterweights. My new T-Trim motor is going to have a 1"ch.
