The Comprehensive LS1 / 4L60e C3 Conversion Thread w/Part Numbers & Costs

[clemsontiger]

I first want to say "thank you" to all of you who have been a help to me during my build. I couldn't even start to name each of you who have chimed in on one of my threads to add your thoughts, but I greatly appreciate it!

The point of this thread is to hopefully help others who are doing LSx swaps to ID part numbers and costs of the project. The problem I ran into when I started my LS1 swap was I couldn't find any one page that actually listed this information. I probably spent 100+ hours on the web searching how to make this work or that work, what I needed to connect this to this or that to that, etc...and while this won't serve as a guide to all, because we've all done this swap in different ways, it may help some.

To give a little more insight into my build, I wanted to build a car I could rely on to drive every day, anywhere I wanted to go...and if I wanted to drive 6hrs to the beach I could. I wanted to build something as reliable as a new car, but I wanted to do it with-in a budget. The LS1/4L60e was the easiest LS combination to achieve my goals. The 5.3 would have probably saved me money, but for the ease of doing a simple take-out swap, with-out having to try to find the correct accessories (which I found by the time I bought I would end up with what I’ve got in the LS1), etc, to make the 5.3 work, I went with the LS1. Power wasn't as big of a deal to me as reliability was, so my LS1/4L60e are completely stock with the exceptions of headers and cold air intake.

The car is a 1972 Corvette small-block, automatic. The engine/trans came out of a 2000 Camaro LS1/4L60e. I used the original 1972 radiator, original steering components (slave, etc), original gauges, and original shifter. With the engine and trans combo price of $2000, it should be noted that I traded my original engine and trans + $2000, so this figure will change for most. It should also be noted that I haven't completed the A/C hook-up as I still need to buy new A/C lines to make the compressor work with my original A/C set-up. I also haven't hooked-up the temp sender yet, so I'm not 100% sure the sender listed will work, but I will update the thread once I do.

I have driven the car about 500 miles since the install, so everything is fairly un-tested, but so far I’ve got nothing but good results to report. Engine temp seems to be running about 210-220 degrees on a 95 degree day after a 30 mile drive (as checked with a OBDII port scanner), oil pressure is 35 lbs +, the engine cranks on the turn of the key every time, runs great, shifts great…and on my first check, which included 60% around town and 40% highway driving, I’m getting 22mpg.


My build page can be found at:
http://www.digitalcorvettes.com/foru...d.php?t=157976

I welcome you to add any information you may have that would help others in their build. I would especially ask for help in part #'s for the fuel system build, as I had this built separately and don't really have all the info on the system that I would like to include. If/when information is added, I'll edit the thread to show below.

Thanks and enjoy!

If an admin can clean-up the spacing above I would greatly appreciate it. It should look more like as follows, w/o the dots:

part description............................. .......price

more details on your exhaust please...how did you make side pipes work? off shelf system?

I must admit that because this was a budget build I went with a cheap set of side pipes. They are from Summit Racing and are made by Patriot. Part number is H-1163 (I think) and cost was around $275. The collector consist of three dummy's and one functional inlet...thus they tie in to the shorty headers real easily. They actually sound much better than I expected...really happy with the sound.

Looks like a good fit in there. It takes a lot of time to write all of this getting everything in a clear concise manner. Nice of you to offer the information to the community.

Just a side note red is really hard to read especially in small print in long paragraphs for some (old people or old monitors). I'm not griping but it might get more readers in a easier to read color.

An update regarding the temp sensor I used:
Napa temp switch part # TS6699 $3.49
This sensor is the perfect thread size but the resistance is wrong to use with the factory gauge...solution, a 47ohm resistor from Radio Shack ($0.99) tied inline. Guauge reads accurate now! This is the cheapest fix I've seen to the temperature switch needed for a LS swap.

outstanding post...i love that you wanted to make this a daily driver. awesome!

Do you know if that Abbott Cable-X box will work with a T56 6-spd manual? I went to tachman1's eBay ad, but it only only says 4LE60, and he doesn't take questions.

Thanks.

Not 100% sure but my guess is yes. I was able to ask him questions somehow, cause I've communicated with him a number of times. If you can't get in touch with him, good Abbott Cable-X and get their phone number. Call and ask for Mary. She is an espert on the little box and can answer any question you may have.

Wow! very detailed informative build-VERY cool!
The vintage style coil covers make are a NICE touch.
AWESOME job!!!

[speeddaddy]

Awesome! Just bookmarked this thread. Great job. Thanks for the post. Car looks great!

[4LitreRR]

Awesome!! Exactly what I would do if I ever bought one of those years.


by the way - I think you can do the following to fix the spacing in your post. Don't hate me if it don't work---

<pre>
Your pricing section
</pre>

[Vettegineer]

I'm in the process of buying parts for my own LS retrofit. I really like your work--it looks fantastic! You don't mention it, but the retro coil covers really make the motor look great. I'd like to acquire a set of those--where did you get them, what extra work did you do to them, and what did the run you? I looked through your build thread, but could not find this data--

Again, great work--you really have an awesome ride for a relatively low price tag--I hope that mine comes out as well.

That is wicked. While I love the LS transfer the herculean effort you have documented may have convinced me to just build an old school v8 instead.

Thanks friend!
