I am building a 83 toyota pickup and I got my hands on an LT1 from the junkyard. I got the long block, water pump, optispark, air injection, Intake, and throttle body for $350. I am going to try to throw it in as a stock setup to get my sticker that says a V8 is leagal in my truck, just in case the law pulls me over and pops the hood. I need to know your thoughts on what year I should set it up as for the smog. I am also going to be using a 700R4. I got my hands on a 97 WS6 computer but it has been modified from stock and I am going to use it as a base setup for when I do the 383 LT1. I need to know how different the wiring harness between the OBDI and OBDII setups. Also I would perferably want to run a setup that came stock with dual exhaust, if not I will run with what I can. This is not going to be in the truck for long because like I said I am building a 383, so I am trying to keep it cheep and simple and stock. Later I will be asking you guys for help with the 383 because I have some very specific things I want from that. But for now I just wanted some opinions on what setup will be quick and and cheep to get it past smog. I am a professional mechanic/fabracator so making it fit and wiring it up and making it run is not a problem. And I have already done a couple of smog legal motor swaps before but they were all TBI. Anyway thanks for any help and I hope to get this thing going soon so you guys can check it out. I will eventualy have the motor pushed back about 1 foot into the cab, 20" of travel in the front widened 10" and a-arms lengthened 12"-14", 30" of travel in the rear, full manual 700R4, Fully caged and braced and made to average 75 mph in the rough stuff.

 

You've already got this on "LT1/LT4 Engine Tech", so it serves no purpose to have it here on Advanced Tech.

What year is your LT1 engine? What kind of car is it out of? You need that basic info, in order to determine what PCM you can or should run. Might want to add that info to your post on LT1/LT4 Engine Tech.

There were no F-Body LT1's with dual exhaust, but there were Y-body LT1's with dual exhaust.
