Ok so I bought a manual body valve, for my th400, I also bought a cooler with a fan, and the GM spacer... forgot the bolts but got them reordered...

do I need anything else to make the TH400 bolt on to my Ls1?

This is my flywheel... can you guys confirm? it has a small inward push in the middle...

Spacer goes before or after Flywheel (flexplate)

Anyone...?

I thought my flexplate was flat, unfortunately it was this bent one... that is bent inward from the middle... how can I make the TH400 fit?

I already have, GM spacer, and GM bolts I want to work with the Stock torque on the TH400!

Thanks

I don't remeber if my had a dip in it or not. I would just replace it. I forget who makes it is ether TCI or ATI with both bolt patterns on it so you can use a ls1 or SBC converter.

I tried my converter and it didn't work with my flexplate...

I posted a picture of my torque converter it looks smaller than the th400 torque converter... someone said its a th350 converter, but I want to make sure, cause I have everything covered now I just want to know which part to change?

Torque converter or Flexplate?

Thanks

this is a pic showing how the bolts of the flexplate are not aligned with the bolts of the converter, I heard about this 298 to 300 mm change, but how can I fix that? can I bore the holes on the flexplate? won't this affect balance?!

Thanks
