LS1 Into a 1992 2 wheel drive Sierra I just got a '92 Sierra with a 350 and 700R4, and I'm wondering how hard it would be a swap in an LS1 with a 4L60E. I have a pretty good idea about the mechanical end of it, but have zero idea about the electrical stuff (gauges, and other wiring).
ps. I am aware of the search feature.... But it wasn't working for me.

If your looking for a plug in harness speartech does great work.
The gauges will all work, voltmeter, and fuel will not be affected at all. For the temp and oilpressure just reuse your sending units and it will work, you should be able to find metric to american adapters. The tach will plug right in if you change the output with HP Tuners of EFI Live 7, or get and external convertor box. The speedo should also plug right in if you remove the DRAC box.

Check out our 60506 or 60508 harnesses at
www.painlessperformance.com
You can download the manual before you buy here. This will give you a good idea of what is electrically involved with this swap.

DRAC defined
The Vehicle Speed Sensor (VSS) Buffer is a solid-state device that is used to change the signal from the speed sensor to a digital signal. The VSS buffer will change the signal from the speed sensor to a signal containing 4000 pulses per mile for the instrument cluster.
The VSS buffer is matched to the final drive and tire size of each vehicle. It must be replaced with the proper buffer to match the final drive and tire size of that vehicle.
CAUTION: If the final drive or tire size is changed for any reason, the buffer must also be changed to continue to produce an accurate speedometer/odometer reading. The incorrect buffer will also affect the anti-lock brakes, engine control module, and cruise control module.
See attached diagram.

I've been doing a little research, and found S&P offers an adapter for the 700 R4's kick down. Does that mean I can still run the 700R4? Or would I be better off with the 4L60E?

Personally I like the 4L60E since the computer controls it, but you can run either. If you have already built up your 700 then you may want to keep it. The 100r4 and 4l60e are basically the same trans, just the 4l60e is electronically controlled. You will have to make a couple other mods to run your 700r4 though, you will need a new LS1 convertor or a crank spacer, you will need to have the trans controls deleted from the computer (if you have a 5.7L LS1 then just reflash the PCM with an M6 program), and you will need to have the VSS signal in the PCM reset to recognize the old style VSS signal or add on a new style VSS sensor.
