What speeds were you going when you shifted? Either way, if you were near the top of third and you went to second, your RPMs would've skyrocketed. Unless you immediately hit the clutch when you saw this happen, you probably revved well over 6k.

Pull the valve covers and take a look.

Also, if you're not hearing anything you might be ok. The usual things that can break while overrevving will be audible for sure.

i didnt push the clutch in but its been sitting for bout an hour so ill start it up and c

all i hear is the lifters as usual and i did look at the tach i think it flew up to 6k and stayed there before i pushed in the clutch which was like 4-7 seconds after also i have 4.10 gears if that makes ne difference

If you didnt go over 6k youll be fine. Even though there is a rev limiter it wont stop you from mechanically over-revving your engine. If you are going too fast for the gear you put it in, the speed of the tires will rev your engine up no matter where you rev limiter is set.

Did the same thing except third to first at 6500. Didnt hurt the engine, but took out the pinion bearing...
If everything sounds ok, then I would say it's probably fine.

I did this twice one nite with my ls1, 6 months later two rods randomly windowed the block at 5500.

I did this once in 06(3-2 shift with new shifter). Had a couple bent pushrods. half hour of work and all was well. To make you feel better, it was tapping pretty loud and the motor was rocking. (stock wore out motor mounts)
