I'm doing a lq4 swap in my 89 k1500 and I'm finally going to pick up a drop out this week. Which set up would be better for my swap? There is an 03 express van that has DBC, and a 03 silverado lq4 that's DBW. I know that the DBC is better for my swap, but will the van harness and fuse box lay out as nice as the truck harness? Also, are the exhaust manifolds and power steering lines different between the two?
