First off, HEy Tex!!!! doesn't look like we are going to have the track this year. hate to get a track started and then lose it. you know how that goes don't you!
Bigchevy, we race in Central Arkansas and Tex has seen one of our pits that we use. We have seen several 60 fronts break under the stress of big boggers and swampers. Boggers are worse than the swampers but both put a lot of stress on front ends in "deep" (4 foot) mud.
On my d-50, i'm running a 340 with "x" heads and 727 auto with 205 transfer case. In the back i have a 9 in with 5:13 and spool turning 35 boggers. In front i have 44 with 4:88's and the 34-9.50 that were mentioned earlier. i run these fronts on a full size truck before i tore it apart and it worked pretty good. i run the drags.
tex was right about the rules. don't build one for one specific set of rules. try to build it to fit as many rules as you can. it gives you more flexabilty!!
