Hey I am new here and think this is a great site. I wanted to put your expert minds to the test in attempting to build a winning mud drag truck. I am buying a 84 K-10 from my cousin. I built the truck and all of the current mods were my ideas. The truck has a mildly built 350 with 9 to 1 compression some pocket ported heads, edelbrock eps, holley truck avanger, headers and a mild retro hyd roller cam. The engine runs well and really doesn't really lack power but could always use more. The rest of the truck is a 2" superlift New 33 12.50 Trxus mt and front and rear 10bts that now have 4.11s and a detroit in back and a front trutrac. The trans is a stock 84 700 and a 208. The truck was built to be a daily driver and a colorado forestry road truck. Now it will be my Nebraska daily driver/farm truck and a weekend mud dragger. I was thinking it needed more power but now I think 33" Boggers will be first. I was also thinking of rear wheel spacers to help the rear follow the front (why are they narrow any way?). These are my class rules. Stock Class Tires 34" or less and must have a DOT. stamp and can not be cut Must be street leagal Headers OK but must have full exh. to rear end with mufflers May have aluminum intake OK, but must be dual plain and no air gaps Must pull 17" of vacume at 1000rpm at intake manifold only Must have factory or factory like bumpers front and back Must have all lights in working order Must be corporate matching No more then 6" total lift Must be naturally aspirated No aftermarket heads, must be factory production head Must have full dash and interior Must Have bench seat or two buckets Must have stock ignition system Stall ok but on bigger then 2000RMP Any suggestions would be of great help. Thanks ahead of time.
