C4 to LS1 swap
I have a 1987 C4 im wanting to put a LS1 in. I wanted to see what input you guys had as far as what it will take. Im 15 and this is my first build but have lots of mechanical experience. First off, im building an autocross car. The car is stripped and set up for a cage. I have the Ls1 motor, a hi stall tourqe converter, a flex plate, and a 700 r4 tranny. What else will I need to make the motor and tranny mate? I also have a painless wiring harness for making the c4 compatible with the ls1. I have a computer and I have ls1edit to change settings. What else would to make this all work? Thanks in advance!

Or you could check with folks on this site that have done (not paid for ) the swap and not the google geniuses...

3 years ago I had an LS3 Hot Cam (GMPP LS376/480 Hot Cam) installed in my '92. Here is the thread with some of the details.

You can also google "C4orce2" and look for the photobucket I have for the car. There is an album there about the build with a lot of pics. Good Luck!

I would recommend using a T56... Just saying. But also with your torque converter if you do choose to use an auto, first find out the torque range of the motor at what rpm, and then choose your converter. Or if you plan on putting in extra mods to the engine, wait till you're done, get your dyno results and choose the converter from there. An engine swap isn't just 123. In some cases, you will be running back and forth getting parts you didn't think you needed to make it work. I suggest getting all the emissions components too so that you don't run into any CELs. In older cars its so much easier, but computer controlled systems make it a real PITA. See if someone has already done it and follow a guide of all the stuff you need.

I had to get an adapter to mate the 700R4 tail shaft to the 4L60E and move the tone ring and align it to the 96 VSS I used.
There is a lot of information in that thread that was posted. That is also a great place to ask questions. GL and if i can help in any way let me know.
