Depends on what you are doing. Are you converting to a 4L80? What are the power levels?

Ill probably only be pushing around 520ish crank. I think this is the one for the 4L60E - LS1

That is the one for 4L60 to LS1. The line I posted was to speed inc. They are $10 cheaper than summit with free shipping.

They are even cheaper direct from TCI. This is from their website:

TCI PART NUMBER #399753
BRAND NEW IN THE BOX TCI SFI APPROVED FLEXPLATE FOR GM LS-SERIES ENGINES 1998-UP.

TCI® Flexplate 1998-2002 Camaro/Firebird LS1, 1999-Up GM Trucks 4.8L/5.3L/6.0L

Flexplates are .035" thicker than stock and the starter ring is welded to both sides of the flexplate for additional strength. Constructed from a high tensile strength material these flexplates resist elongation and cracking. All 168 tooth flexplates are sized for stock 3/8" mounting bolts and can be easily drilled for 7/16" diameter high performance torque converter applications and are SFI 29.1 approved.
