In the next week or so I'm going to be picking up a complete LT1 engine and transmission from a '94 Impala SS. I have access to the entire car and the guy said I can take anything I need.

The engine will be going into my '91 Camaro RS, it currently has the TBI 305

Here are the things I believe to be true, so please correct me if I'm wrong on anything here:

-being a '94 engine this means it is OBD1, and has MAF
-If I use the engine mounts from the Impala I won't have to modify the passenger side mount to clear A/C (but I will still have to modify the x-member, and get the 90 degree AC fittings)
-The Impala power steering lines will fit with some slight bending
-If I have the complete Impala SS wiring harness and ECM and the complete TBI 305 harness the wiring will be pretty straightforward (I've already rewired part of the '91 after an electrical fire so I'm pretty familiar with the wiring in there). I've seen all the diagrams
-I should be able to use the VATS module from the Impala, as long as I measure the key to get the right resistor value

Here's what I'm planning on getting from the donor car when I go to pick up the motor (please tell me if there's anything else I should grab to make my life easier)

-Engine and transmission (automatic)
-Complete wiring harness and ECM
-VATS module
-Ignition module
-A/C and powersteering lines
-Engine mounts
-coolant lines
-under hood fuse and relay box
-radiator fans
-throttle cable
-???

I've been researching a lot on the wiring, and found a lot of diagrams, but was wondering if there is anything in particular I should know about swapping the Impala SS harness into a '91 F-body?

I recommend moving your battery to the passenger side if it's not already there. Then you can use the power cables from the impala. It branches off into 3 different wires. 1 goes to the alt., 1 goes to the starter, and the other goes onto the post of the underhood fuse box. Then G1(orange wire) from the black 37pin connector needs to connect to a switched ignition source. Now when the key is turned on everything in the lt1 harness has power.

Wire C2(gray wire) to the wire that runs back to your fuel pump. You can find it in the clear c207 connector under your dash by your old ecm.

Hope this helps some. If you have any more ?'s just ask. I just did this swap with a 95 impala ss.

 

Yeah my battery is in the front passenger side, in front of the coolant reservoir. Same spot as in the Impala, So I can grab the complete battery cable and harness, everything.

I went and saw the car yesterday, engine is good runs strong, will be pulling it out this weekend
