A stroker crank will not affect compression. I dont know where you got that idea. The 347 used to have a oil consumption issue due to the short skirt length and the rings having to be so close together, that has been cured in recent years. My father and I have ran a 700hp Vortech charged 347stroker in a 63 Fairlane for about 4years without a single downside.
