1993 GMC Sierra Z71
Question:
I just bought this truck with 64,000 miles on it. It has a 4.3L V-6, 5 speed. I was wondering if anybody had some suggestions of what I can do to improve the performance of my truck. Any advice is appreciated. Thanks
Response:
350 is almost a direct swap. Pretty reliable form of upgrade if you ask me. May need just the chip or even the whole harness/ECU, depending on the fuel delivery system used.
