Well just picked up a th400,that I got a killer deal on!..what flywheel will I need to run to bolt up?I have the flat one without spacer..when I go to buy my converter,do I just get it for the th400?..also it looks like only 5 bolts will work,bolting the bell housing to the block..the th400 doesn't have the very top one..and the bolt isn't tapped for the one just to the right on the block..
Th400 flex plate Tci pn# 399753, just use the bolts that line up. I've been running mine like that for a long time with no issues.
Tci makes a ls to 400 flywheel. And the spacer for the converter u need. Hit zach up as he done same swap and has all part numbers. Screen name is chevrolade
Awesome,thanks alot guys!
you can also run a Circle D converter and flexplate. Thats what im running. It was $1100 for the pair
that spacer that comes with the tci flywheel for the ls engines is a pos!
it basically extends the snout of the converter so it goes into the crank.
that spacer free floats/spins.
the noise is creates sounds like you just screwed the trans install up.
solution, tig weld the spacer to the crank, only takes a few tiny tig tacks.
Ok thanks for the heads up Allen..is there no way I can run the flywheel I already have,and just buy a converter for the th400 to Ls?
as long as the offset is fine, you can opt to drill out the holes on the flexplate. i haven't done this, we either get the converter bolt holes mounts built for the trans/engine type or use the tci plate.
The flexplate from Circle D is $150 and is a direct bolt on and its SFI certified
