As some may know, I am doing a TBI swap in my '86 crew cab. I am making it 100 percent emission compliant. So far I have gathered most of my parts, luckily I know a guy that has a has chevy truck junkyard and for a flat rate he is getting me the rest of everything I need to do the swap. Also I picked up a brand new wiring harness from Tom at turbo city, I havent started with that part of it but I will tell you his customer service is already great. He has spent much of his time in person talking to me about my install. But I digress, I need pictures of a stock 454 (or relatively stock) out of preferably an '87. Form speaking with Tom he said those 454's did not come with a knock sensor, so as a result no esc module. I have a few other questions as well. After Im done Im taking it to a smog nazi....eerrr...I mean ref to have it certified. And being that Im in Cali I need it to comply exactly with how a 1 ton crew cab dually from 1987 came equipped from the factory. So your pictures and/or help in this matter would be greatly appreciated.
