PostSubject: The Hypothetical LT1 Swap   Fri Feb 03, 2012 5:13 pm

So lets say, all hypothetical like.. I get a LT1 car that no longer is really roadworthy, but has a low mile drivetrain. What do I need to get said LT1 into my car? Yes I know I made this thread a long long time ago. But I can't find it and I forget things very easy. It's a complete car so I'll presumably have all the needed parts.

Let me know if i'm missing anything:

LT1
Trans
PCM
wiring harness
fuel sending unit
fuel pump

Crossmember and exhaust would work better than the 93's you have.
Also you might need to cut the frame where the a/c compressor is for clearance.
You also need the coolant bucket and radiator/electric fans, throttle cables, and gas lines.

The fuel lines in the lt1 are nylon all the way up to the quick disconnect. They also run the drivers side as opposed to the 91-93 passenger side setup you be better off just running the whole fuel line to the back instead of trying to splice them in. The throttle cable can be swapped from the pedal I believe. I have boxes of conversion stuff still around here somewhere if anything is missing off the donor. You can also come look the caddy over to see the lt1 up close instead of searching the JY for a complete one.

Well, as I said, i'd have a complete car so I wouldn't have to buy anything... hopefully Laughing

This is going to take more planning... I mean... umm, hypothesizing...

You would have to either cut and patch a spot on the frame for the air compressor, or use a a/c delete pully. You would not need the sending unit, but you will need the pump. Sending units should be the same.

You would be better off just buying a LT1 car. If I was going to update your car, I would be thinking LSx power.

I wish. No monies for new toys. I just have access to the cheap drivetrain, figured i'd make it a winter project. But like Billy said, if i'm going to put that much work into it, I may as well do an LSx swap, but the car is a DD so its not really worth it to me.
