Hey guys I want to start off saying I am loving some of your cars I am seeing here. I Currently have a 3400 series Monte, A friend of mine is looking to sell me a L67 that had about 80k miles on it. Is the motor the only thing required to put this inside my Monte? I am trying to follow some of the post in the other topics following the swap threads but some of it goes over my head. Please try and work with a new user lol.

 

welcome to mcf!!! if you have a 3400 you will have to swap the whole engine over to the 3800 engine. also will need the pcm and im not sure about the trans.

 

You will need engine with all the sensors, transmission, wiring harness, PCM, axles

 

What car is the L67 coming from?

 

Thanks for all the comments guys and it is coming from a 2000 Grand Prix. I guess I should look online far a entire car to transfer the parts from.

 

your trans could work. im pretty sure your 3400 has a 4t65e you would just need the PCM reprogrammed for that trans. if you have a 4t60e then you might be able to run a 96 Riviera pcm as those had the L67 and a 4t60e. by retaining your trans you will not have to change axles.

Main things you will need:
-Engine
-Power steering high psi line. the lower psi should still work.
-transmission lines may need to be swapped
-AC lines may need to be changed
-coolant lines to heater core
-PCM tuned for any differences like mentioned above.
-Harness from SS mc
-throttle cable may be different. I know my DOHC cable was diff then the 3800's
-exhaust manifolds and down pipe OR Headers *now is the time to do headers as it is much easier to install while the engine is going in.
