    I am about to do this swap as well. My brother put one in his S-10 last year. I would advise you to start reading the camaro message boards ( such as this one ) to learn about the LT1 if you haven't already. A couple of things that stick out from my brothers conversion are:

    1. A/C compressor hits frame on pass side (use A/C delete pulley and notch frame or get pulley setup from Vette.
    2. Wiring for PCM can be tricky. My brother used a painless harness modified by some company in TX. I will be using factory setup from 94 Camaro.
    3. Cooling- LT1 reverse flow connects to radiator differently than old SBC. Try to use hose arangement from Camaro or Vette.
    4. Opti-Spark (distributor) weak link in LT1. Try not to get it wet and convert to vented Opti if you have 92-94 engine.

    Good luck and keep in touch about how it is coming along! /forums/images/graemlins/thumb.gif

    Well to start this motor is out of a 95 Vette it has all the wireing,ecm and pcm. Just trying to figure out how to get around the VATS. The A/c compressor is on the drivers side and on top so that shouldn't be a problem,besides I'm thinking about removeing it. Thanks Any other sugestions are welcomed /forums/images/graemlins/thinking.gif

    Thats awesome you have a Vette engine. Check out some of the Camaro messeage boards. Search around for some info on PCM programming. I found a few guys that do programming pretty cheap. You can have the VATS as well as the emmisions equipment ommitted from the PCM. I also recently found a guy that had some wiring schematics posted on his website for a 95 Camaro. Could help with your conversion. I would post some links, but just installed a new harddrive and lost all my favorites. If I come across anything, I will let you know.

    I have read good and bad reviews about Dynaspark. Some of the Camaro guys seem to think it is overpriced. I don't know....

    dynaspark seems to be the less expensive replacement for optispark, when compared to the LS1 COP setup... at least thats what the LT1 junkies at work preach LOL..
