[Red Mustang Gt 46]

Well driver technique is all in the numbers but it is not unusual for 5.0 fox bodies to run anywhere from mid 14's to mid 13's in the 1/4 with just a gear swap. When I owned my 5.0's back 1985 and 1992, I did the gear swap in both and the difference was like night and day. There's so much you can do with 5.0 it isn't even funny...with a small budget.

Only way to get the definitive answer is to "DO IT"...

Good luck...
