2000hciz28

Ive got a 2000 z28 m6 t56 stock 10 bolt, hci ls1 putting down around 430hp, its not wanting to go into 3rd gear wife open throttle. It shifts smooth as silk easing around but one your wot it wont go into 3rd. Is the fork broke or do I need subframe connectors and chromoly torque arm?

I bet you anything it has nothing to do with your transmission and everything to do with your shifter. I assume you're running the stock shifter. Upgrade to a MGW and you won't have that problem anymore.

3-4 shift fork wallows at the shift rail - most common
broken or missing keys could fail to pre-load the ring - still common
blocker ring could be worn (Just fixed 3rd on a Camaro with this)

Inadequate clutch release can show up as a third gear issue if the blocker ring is marginal, but that's not common to be single-gear isolated.
