A guy like GTXJOHN who may run an R3 block in his type of class racing may have to use the 59 degree and it is what it is......but nobody in their right minds would "WANT" to run 59 degree in an R3 block, not saying that sometimes that's all that was available to buy and also they are cheaper for a reason and so it may suit a persons budget and or availability BUT point remains the same.......NOBODY WOULD WANT 59 over 48
