Any LT1 350 owners on here?

[JWheeler331]

Anyone of you put a LT1 350 in their truck?

My cousin has had a 1997 Trans Am that was nearly brand new in terms of use......been sitting in his yard for the last 10 years or so due to hitting a deer. I was asking him about the motor and he said I could have it if I hauled off the whole car. This was a top of the line Trans Am and I figure I could sell enough of the other parts to have the motor redone.

Just wondering if anyone else has one of these motors in their truck and how hard it was to make the swap?

I remember riding in that car and with its 5 speed manual tranny and whatever rearend it has.....the car was pretty awesome

I don't have one in a truck (but there are a few guys here that do). I have three of them in cars, one having a T56 six speed that I swapped in. If it is in fact an LT1 Trans Am (not a firebird), and it is manual trans, it will be the T56. Not a 5 speed. Worth the price of hauling that car away. With a cam/rocker/spring swap, you will get an easy 350-400 HP out of that LT1 easily. If you have any other questions, just let me know, I've been working on LT1s for almost 15 years.

Thanks. I will call him and get some more details. I am pretty sure it's the Trans Am. It has a manual and I was prob wrong when I said 5 speed. My truck is an auto but I figured the motor and tranny would be worth hauling it off. It was a really nice car but he hit a deer and messes up the nose of the car. He parked it at my grandmothers and then ended up moving to fla. it has sat for several years there.

Piece of cake.

I'm doing one right now. It's a good motor, and it's a really clean setup. Also, there are several sites about the LT1, wiring, AC pump relocation, etc. for installing into older cars/trucks. For the price, you can't go wrong....

I guess that was my main concern.... The wiring and computer stuff.

Any pics of your build?

How are you doing the wiring?

very clean.
Here's mine. '95 Corvette LT1 in my '66 1/2-ton Stepside.



Get the whole car. Use the ECM and modify the wiring harness from it. Definitely get the Factory Service Manual for the donor car. Sell or throw away what you don't use. Take your time. It's not particularly difficult, but there are a TON of details to consider.
I bought a lightly-totaled, low-mileage car and used everything that I could from it.
Started it for the first time last Friday, BTW.

I have one from a 2004 Oklahoma Highway Patrol Camaro, have the basic wiring harness and the computer, got the serpetine belt rearranger but have just not got started on the change over yet. Mine is not as pretty as the corvette motors but we did not pay a lot for it. The Aluminum heads keep talking to me and I think it will make a good winter project ......Kieth

They sure do look nice and clean under the hood.

I think FAST makes a stand alone EFI controller for this, can't remember, but I think Painless makes a ready to run harness that gets rid of all the extras you don't need.

Thanks y'all. I'm going to look into it more. I will get it reguardless and then just decide what I want to do after more research.

Yeah, I see there are lots of things to do and consider with these motors.

My truck right now does not have ANY air condition. I will be getting the whole car though so I can sell the parts that I dont need to possibly help with other expenses.

I asked my dad who lives on the same property if it was a Six Speed and he seems to think it is an Automatic.....so I may have been wrong on the tranny. Still not a bad deal though.....for just the price of hauling it off I get a nice LT350 plus and bunch of parts to sell.

[JWheeler331]

Im about 300 miles from the car but my father lives right there nearby so I had him go by and take a few pictures. He forgot to take one of the main thing......THE MOTOR.

But.....you can see, it has plenty of usable parts to sell and help cover some of the cost of rebuilding the LT1350. I was wrong though and it is an Automatic Tranny.

Anyone know what Transmission would have been in this car?

What is that gas tank from?
Posted via Mobile Device

[Looking4shade]

Here's a picture of the engine stands. The Right stands Back edge actually hangs off the crossmember A little bit To give clearance for the compressor. You can Build and L bracket to bolt it or just weld it to the crossmember I can't find my picture of that right now . I made a bracket and bolted it down. If you buy the bracket to move the compressor to the other side You can move the motor mount forward in the bolthole for the compressor And solve that problem. Gas tank is out of a jeep wrangler look at post above.

I've got a 96 LT1 in my truck and love it. I moved the passenger motor mount on the motor to the the standard sbc location. Had to grind the bracket a little. I notched my frame for the AC. Basically the part that is bent up from factory, I bent that portion down. I got my harness from techrods and works awesome. Tell him what you want and done. $410 with the fan option I got. The fuel system will be the biggest expense. Got my lines from pure choice motorsports. I went with a tanks Inc PA series fuel pump. Went with the bigger one for $10 extra. Fired over fist try. Oh, you'll need posi now if you don't have it.

That looks nice. Yeah, I am figuring on a new posi rear end for sure.

Automatic 4L60E.

[Jonboy]

Should be a 4L60E. The swap is actually a pretty good swap. If it is low mileage, you might not even need to go through it. I had one in a '79 SWB, and I really liked it. For the stand alone harness, check out www.fuelinjectionconnection.com . I bought mine with the swap started, but had to fix a lot of the wiring. Since the connectors are almost 20 years old, a lot of them were damaged. Mine also had accessory brackets from Alan Groves. They are pretty nice pieces, and nicely priced as well.

Would this be a good tranny to possibly just keep with the motor and use with the truck? Right now my truck has a Turbo 350.

I will have to check and see how many miles are on the motor. I dont think it was all that many but I am not 100% sure just how many.

Yes, as mentioned, it is essentially a electronically controlled 700R4 (later 700R4s actually got the 4L60 designation, without the "E"), it is a good transmission, and you will gain overdrive.

Sounds pretty good. I had a 700R4 in an Iroc Z years ago and thought it was a pretty nice tranny.
