C4 + LS1 + T-56 = Good times! by subtlez28

4 minute(s) of a 26 minute read

I did some work on the gas tank today. I drained it as much as I could and washed it out w water days ago. It still smells like gas but is dry. I was worried about going after the rust (explosion). Today I bit the bullet and hit it with a plastic media wheel on a drill. It cleaned up well, and no sparks...

I threw a quick coat of paint on:

Down side is the cheap bolt extractor kit I bought at AZ did not help w the two broken bolts. However I did bust several drill bits... Those tank bolts are hard!

I switched over the wiring on the late C4 sending unit. I just pulled the factory wires from the old 3 plug connector, the new 4 conector, and put the new unit wires in the old (3) connector. The new sender didn't even use the 3rd place, so I think I'm good.

I also put in my Racetronics pump and sending wiring (just 2 splices - it was for the 84 sending unit).

I got my new (to me) harness in yesterday! I originally had an S&P harness for the LS1 and 4L60E that came in the car. I was going to modify it for the T56. But then I found a great deal on a used S&P harness for an LS1/T56 combo, so I jumped on it.

For anyone doing a similar swap with an auto, my other harness is currently in classifieds.

$650 shipped.

I'm sure I'll regret this later, but the truth is I have not made this car a priority in too long...

Would anyone who has followed this build be interested in taking over?

I'm fairly close to completion. Things that come to mind it still needs:

1- Engine mounts or plate

2- Wiring, keep in mind I have a nice plug and play engine/trans harness and ECU

3- Clutch hydraulics (have the parts)

4- Seats (the only part I really do not have at the moment)

I have new:

-Melrose Swap headers

-Dewitts LS1 Swap Radiator

-Water pump, balancer etc

-Laser cut Aluminum dash w Auto-meter Guages

Completed:

-D44 inspected and installed new rear hub/bearings and ARP studs

-Full Banski rear suspension

-Racetronics fuel pump , new classic tube fuel line

-Liberty Face-plated T56 six speed with C-beam bracket

-98 LS1 with LS6 intake and stand alone harness/ECU

-C5 front brakes

-17x11 front and 17x13 rear wheels/tires

$10k would take it home with the LS1, T56 and all mentioned parts. I have much more in it!

I would consider trades up or down (plus or minus cash). Manual trans C5, G8, GTO, CTS-V or LS1 F-bodies come to mind.

I've been pretty candid with this thread. No surprises.

I don't "need" to sell it, but I have been facing the reality I don't have time for this project at the moment...
