Re: Project racing $$$. 1968 GMC SWB 5.3/4l60E Build
We had fender clearance issues with the front tire and wheel combination, so sadly we had to raise the truck up 1" in the front and 2" in the rear. We ended up running the dropped spindals up front with lowering springs, stock shackles in the rear, flipped the leafs, and ended up taking some leafs out of a longbed camper special. They had more of and arch and are a little stiffer. This was all benificial since Im going to be using it as my daily driver. We emded up with a 3"/5" drop and were still able to run the old school wheels with the fat tires. Down the road I may get some wheels custom made and drop it back down, but until then this will do. Also, we put the truck on the chassis dyno and had the tire sizes/shift points/air fuel mix calibrated and ended up with 260hp/300tq at the rear wheels. Plenty of power and very easy to light em up through 2nd/3rd gear. It looks and runs great!
