I have a 1988 crew cab long bed one ton with a 454 out of a 94 suburban that is carbourated, I did not do this work. I purchased to pickup 2 years ago and the previous owner had it for 9 years and did not do the engine swap either but claimed it was a 496, but I digress. The problem I had/have it the damn thing caught on fire while I was in the school for no more than 10 minuets. I came outside to see smoke coming from the hood, I found a fire extinguisher and got it out. I got lucky and it was only an electrical fire, the issue I have is that it was not running and the ignition was off. The drive from my apartment to the college is no more than a mile and I was no where close to operating temp when I shut him down. I don't know if it started with a wire or inside the distributor itself, because the cap is all melted and now has holes in it as well as that there are wires that got burnt up. I tried to find information on this but found nothing, I think all I will need is a distributor and plug wires as well as a new K&N, and splice in some new wires. Has anyone had or heard of this happening, any information would be great thank you.
