Features:

  • This kit includes the parts required to bolt a GM TH350, 700R4, 200-4R, or Powerglide transmission behind a Gen III LS engine
  • Includes flex plate, torque converter adapter sleeve, flex plate bolts, and torque converter bolts
  • Works with 10.75" and 11.066" (11.1") torque converter bolt patterns
  • Works with factory LS starter to reduce conversion costs
  • Flexplate is .035" thicker than stock which meets SFI 29.1 certification
Will not work with converters with the larger 11.5" bolt pattern.

This is the second time I've done a LS swap in an older GM vehicle. I've used this flexplate to mate up a LS to a TH350 in a 74 Chevy Impala. Now I'm in the process of LS swapping in a 84 Chevy K30 with a TH400 and ran into problems. The flexplate has holes for 10.75" and 11.063" converter bolt pattern. The converter that was in the TH400 has the larger 11.5" bolt pattern. So I either have to elongate the holes or buy a different flexplate with the correct 11.5" bolt pattern. I've since found out that p/n Z270 flexplate has everything needed as well as the larger 11.5" bolt pattern to work with the larger coverter bolt pattern but cannot confirm. Hope this helps.

6L to 700R4 Conversion

Worked great of swapping a 6.0L LS from a Silverado 2500 into a Humvee. Bolted up to our 6L to a 700R4

Perfect!

Works awesome for my 5.3 to th400 and all ARP 👍
