Those 5.0's are junk. It'll be a good race IMO but I think you'd take em. I've seen most stock/bolt-on (I/H/E) 5.0 Fox's not break out of 14's...its when they start doing builds is when you need to think about backing off
I'd get rid of the U-Bend, and put a lower temp T-stat in it and it'll run a BUNCH better too![]()
