I have been around pulling a little, done a little diesel work stock and helped a good friend build a 9500# Limited Pro tractor from the ground up last winter, it was a blast, lot of hard work. Pretty cool with 1500hp and 3500# on the dyno tho!
Pullers are veeery tight lipped for sure.
I sent a PM, by the way your truck sounds great. Need more FE's pulling!!
