we have 5 people in our "crew" (if thats what you want to call it) that have 5.4 rod, 3.4 crank 347's, and 2 331's all of which have never had a problem AT ALL with the piston "side loading" on the cylinder wall.
your reputable engine builder has seen 3-347's go bad....any ford dealership IM SURE has replaced more than 3 factory motors under warranty.
which by what you are saying.......the 347 is more reliable than a factory 302?
everytime this comes up, there are always people who think both ways. but in my opinion people emphasize the VERY FEW 347 casualties way too much, take in to consideration that:
FORD REPLACES FACTORY MOTORS, MORE OFTEN THAN THE AFTERMARKET CONSUMER REPLACES 347'S, im sure there are more 302's than 347's out there but im sure the percentage of replacement is the same if not less for a 347
