Default Flexplate advice?

Looking to finally do an overdue upgrade on the flexplate in my '94 Z28.

Need a LT1-era 4L60E compatible one that will handle ~430 RWHP in a 3360 raceweight car looking to run Low 11's NA (Mostly) and Mid 10's on spray (occasionally).

Which one and best place to buy?

Thanks in advance!
Todd

check out New Products on TCI site, part#399173 for LT1 or dual bolt pattern LS! part#399753 might do it? both SFI approved so should cope with 10s

Anyone else? Anyone that is using a certain flexplate already so they can attest to it?

I am using the TCI SF29 flexplate on my 01 Z28. The word I got from the transmission shop that did the work, "Is that my whole car will fall apart before the flexplate goes". They were very impressed with the unit.
