AFAIK painless doesn't make OE replacement harnesses for the LT1 F-Car. Just parts/pieces/pigtails. I recently emailed them hunting for a replacement for my LT1.
Since you would be using it in a classic car, I have never heard anything bad about painless but have never used them either. Sorry I can't be of more help.

Not sure if you mean the harness or car. here is the harness http://www.painlessperformance.com/w...rchField=60502
the pictures of the 69 corvette are going to be a while I haven't built a web page yet. I am sending the engine out to the machine shop when I get back from vacation. It wont be anything special just a nice 350 with a small cam haven't picked anything specific yet.
I though about using a stock harness. This has all the relays and stuff built right into it even the one for the fuel pump. When they modified your harness did they do that? or did they just strip out the unnecessary stuff?

cool Ill have to check them out and see what we they can do as apposed to the painless set up. I really appreciate the tip. One last thing for the did that come set up for fans? I am guessing if I asked them for something they could make it happen though.

Keep in mind that the term "Painless" should ONLY be used in context to identify the name of the company. There is still much hard wiring to do - cutting, crimping, soldering, shrink-wrapping, taping, making various connections/grounds, etc. It is a lengthy process if you've never done it before.

I guess we will just have to see how it goes.

If you contact them just tell them what you are doing and see if they'll modify your harness. They used to sell complete LT1 packages but the LT1 is almost an antique. Now that I think about it, it's been 11 years since I did the swap. Hopefully they can still help.
Well for what it's worth back in the day I had an original 73 Z28 that the previous owner had hacked up the harness and age also played a factor in all of the electrical shorts and gremlins. I got one of their 18 circuit muscle car harnesses and completely rewired the car from bumper to bumper and it was easy as each wirle was labeled the entire length of the wire as to what it was for and the only connectors which i had to splice were the rear tail light pigtails.
they said they don't touch lt1 stuff anymore because they are to busy with lsx stuff. personally I think it is silly because work is work but its not my business so.

I can't blame them to be honest. The LTX platform spanned 5 years 15-20 years ago while the LSX platform extends from 97 to current - a span of 15 years and it's still going strong. Makes no (business) sense to keep investing in dead technology.
Its not really a big deal I will figure something out. Worse comes to worse I will sit down with some wiring diagram and figure it out on my own. If you don't do it you will never learn right?
I used the painless 60502 harness when I had an LT1 in my camaro. It was a great piece and everything was clearly labeled. It uses the factory style 8051 PCM and was easy to install. Painless' tech support was really helpful when I had some questions.
