Hi guys! New to this board and new to LS1's. I just purchased a 1999 LS1 for my jeep and am running a TH350 behind it. What do I need to do for this to work? I have heard of flexplate/converter issues and I'm not sure what to do, if anything, with the computer. Any help would be greatly appreciated! Thanks!

 

i used stock flexplate with spacers between flexplate and converter..very easy to do
