putting a th350 in my 96 z what flex plate do i need to get or can i use my stock one off the 4l60?
and what about tunning do i need to change anything ?

 

any help?

 

The flex plate will depend on your converter tou got or are getting..

a stock lt1 flex plate has a converter bolt spacing of 10.75 and if your converter is that then you can use it..

My th350 stall is a hughs gm45 so i had to go with quick time rm-932 to work with that seeing my bolt spacing on mine is 11.50

As for the pc all you have to do is have some one swap it to read you have a m6 and your set wont get any ses codes..if you dont you will get codes
