November 13, 2011i have a 91 ck 1500 5.7 and a 98 k1500 with a 1500. has anyone did a swap such as this, is it possible? the 91 has major rust issues good solid drive train, the 98 has motor problems and excellant body. can the engine puter and harness be swapped into the 98 from the 91? everyone has been extremely helpful before so i thought i would throw this out there. thanks all.

November 14, 2011The computer systems are different. OB1 is up to 94 i believe and after that is OB2. I believe the block it self is the same besides the heads. It would probably be more cost effective to sell you 91 to get the cash to rebuild the 98` motor.
