Hello, i am going to do the TH350 swap in my iroc, i am wondering what flexplate to use with the th350 converter, i am going to use the TCI street fighter (241000) what flexplate does this converter use? and also do i need a 153 or 168 tooth flywheel? this converter is only compatable with a 168 tooth, if i convert do i need a new starter too?? if this converter isnt compatable, do you have any other suggestions??

 

you use your stock 700R4 flexplate

 

yeah thanks just figured it out, there are 2 different converters small and large bolt patterns, thanks

 

I found that out a while ago too...my 406 stock flexplate has been bolted to a TH400, a TH350 and my 700R4...
