Cost to convert From M6 to Th350-400 Well i have thought about doing this for a while now and i believe i am going to start it next month. i just had some questions
First how much was total cost for you guys that swapped over to a turbo 350/400.
And two i will be having my father build the trans .I have one from a 86 trans am drag car that needs Freshened up and he says roughly 700 bucks to have it Gone through and Built strong.I will be at (400-415rwhp)
Just curious are they any major wiring you have to do when swapping over ,because that is the major thing that has kept me from doing this sooner I am scared of screwing the wiring up if their is a lot of it.
Because i was told that you could by pass the wiring to the pcm because i am a m6 i would just have to fix the Clutch switch so it would start.( i will be leaving my M6 pedals in in case of selling the car)

I'm going to do this on the girlfriends car. I'll try using the Clutch switch input from the pcm just wired to the nuetral safety switch on the new auto shifter. Then I'll just have to trace the reverse light switch and connect it to the new shifter as well.
As far as cost, I'm thinking it's gonna be about what you stated, only selling the M6 will help offset the costs.
