LS1 & Turbo400 Question

[FlynBrian]

Hello Everybody,
New to the board, KickAss site! I have a 99 Vette LS1 and a Transbraked Turbo400 trans, I have a 99S10 Extreme i'm dropping this into, my question is, any of you that have put a Turbo 400 behind your LS1, what did you use for a Flexplate? I prefer a SFI flexplate if it's available. I was told the Turbo 400 bolts up you just can't use one of the bolt holes on the block, does anyone make a aftermarket sfi bell to bolt a T400 up to a LS1? Any info you can give I would appreciate, Thanks,
Brian

to use an after market bellhousing on a th400, you'd have to cut the one on there now off. they make blankets to put over the housing that's SFI approved. there is a company that makes a th400 with removeable bellhousing, i just don't remember who. check TCI and B&M.

also, Yank sells a th400 with conversion parts as well.
