i am getting the LS1 out of my buddies 2000 6-speed SS. he is keeping the PCM and harness and installing a LS7.

i am going to put the LS1 it in my 79 1/2 ton with a th350.

would it be easier if i just bought him a new PCM to be tuned for his LS7 and just used the PCM out of his car in my truck?

i guess what i am asking is, if we just swap the motor from his car to my truck, the tune should not need to be changed, right?

or will the different gear ratio and tire size need to by changed in the PCM? if this is the case, it dosnt really matter if buy a new PCM or use his.

thanks

I don't think he can use that LS1 PCM with an LS7 without lots of work, and possibly not even then.

yep. take the pcm with you and have your friend get an ls7 pcm for his new motor. and its a little bit more complicated than just tire size and gear ratio that would need to be changed in the pcm for that ls7
