Are there options for the adapters to bolt up my 400 to my lq9? Brands, quality and pricing aprcd. Thanks.

pretty sure it bolts right up...do you mean for the flywheel to converter?

Bellhousing bolts up. You need a spacer for the flywheel, I know the 6.0s with 4L80Es have them. You can probably find a used one on ebay cheap enough. Not sure who sells them new. You need the longer bolts as well.

mine bolted up straight away...

The spacer is what i am after. I know the bellhousing lines up. I actually had to tap a blank on the trans that wasent used on whatever application it was in back in the day. I would like to get this adapter new as this is a very through and expenisve build...

I would actually suggest an SFI flexplate over the stock plate with adapter. Does the converter have a dual bolt pattern?

Chris @ Circle D is the best, he built me a T400 converter 4600-4800 with a LS front. The converter hooks unreal, just like a daily driver.

If you're looking for a bellhousing/scattershield I would suggest Quicktime Performance. The quality is the best I've seen so far. McLeod would be second to them but Quicktime makes a number of conversion bellhousings for cross platform/cross engine setups.

If this is just a street car, all you need is a replacement flywheel kit for a truck equipped with the 4l80E. I paid $50 for the flyweel & spacer assembly brand new from GM.

GM #12621399 Flywheel & spacer assy (used to adapt LSX motors to old school automatic transmission)

I run mid 11s with this set up. If you plan to go real fast, hughs has a nice SFI flex plate and spacer set up.

X2 on Chris at Circle D. I am very please with my Circle D converter.

Im going to have to go with the SFI flex plate. Making the car 100% nhra legal...eh. Im figuring on running mid-high nines. But prob not going to beat it to death on the strip (50 passes a year ish)

I bought a JW performance bellhousing for my th350 when I forgot to take a bellhousing bolt out and broke mine. (yea i know im an idiot) but it had the LS bolt pattern. Summit sells them.
