Engine swap: 86 carbed into 88 TBI - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Recently picked up an 88 R30 dump, originally 350 4 speed 2wd, minus the engine. Donor truck (complete)
is an 86 C30 350 4 speed non TBI. Is this an easy swap where for wiring you just change the engine harness from the 86 with the 88? Or is there dash wiring involved. Remember, this is a dump truck, not a show truck or daily driver, so COST is the issue here. Any one done this? thanks for all the help. I see threads with conversions from carbed to TBI, couldn't find any in reverse.
