It's not rocket science, just take a carbide burr and oblong the hole.
Nice part, but $229 more than the above mod...

Okay so let me get this right. I'm a noob when is comes to finding out what fits and not when mounthing the LS engine to the TH400. This is what i have so fare, a LS1 with stock flex plate and a TH400 with the stock torque converter.
So if i just buy this kit everything is gonna bolt up and work and I'll need nothing extra in addition I'll be able to use the stock toque converter? http://www.speedwaymotors.com/LS1-En...ign=GoogleBase
I also hear of a crank spacer, will i need that?
Thanks,
JP

I spent around $70 with GMPP (see my earlier post), used a $20 JYD flywheel for the engine and a carbide bit equipped die grinder to adjust the holes outward. It's a mod that has been done a ton of times and works very well. You only elongate the holes a few mm and I used my torque converter as a template so I knew when to stop. MAYBE took 20 minutes but I have a very well prepared home shop. I'm not racing and my engine is stock so I don't need an SFI approved flywheel and won't spend the $ for one - until it is necessary.
That is the curved Gen III flexplate. To make that work with a 1997 or older transmission you need spacer PN 12563532 ($37) and six longer bolts PN 12563533 ($25).
I have seen a few early truck engines with a crank snout .400 longer (sticks out from the back of the block) while the normal Gen III cranks are flush with the rear seal. Those engines don't need this adapter or bolts and are easy to spot with the engine away from the transmission.

I am wondering if this adapter ring probably comes from the factory on the LQ4s in trucks equipped with the 4l80 trans? If so, they could be had at salvage yards when buying a flywheel maybe?
Older trannies with the LS motors I just found a really sweet deal and an easy solution to older trannies with the LS motors.
How about a $50 solution to the problem that comes with flywheel, spacer and bolts all new from GM?
VIOLA!

Verdad Gallardo Yes it will. The only thing you have to do is lightly elongate the torque converter bolt holes 1 to 2 mm with a die grinder. Apparently, many savvy people have been doing this for years.

Hughes stuff is total junk. I had a flexplate from them that rubbed the bellhousing it was so far out. .090 run out.
Any type of performance needs a good flexplate. You can hurt yourself when one comes appart.
The TCI stuff is very very nice. I used one with my ford c4 to lsx it was very easy.
