'86 Silverado engine swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Howdy,

I was hoping someone could help me because I'm stuck. I have an '86 Silverado which had the original 305 in it when I got it. Instead of rebuilding it, I had a 350 engine from a 1990 Suburban. The 305 was carbureted but the 350 was fuel injected. I was able to have the carb replace the injection and it ran really well for a few weeks then putted out! I was told I'd have to rewire complete with new harness to 1990 Suburban standards. Is that true?

Thank for any advice!
