A big flame came out of Exhuast then the car bogged down didn't want to start then finnaly started but it runs like something flooded no check light come on no oil anywhere it tried to idle up to normal then went back to not running good could it filed the plugs or something or blow something or maybe bent a valve any ideas would be apriciated

Well, I do not believe there is an over-rev protection when downshifting, only for upshifting. You might want to see if any codes have been set on the DIC and post them up if there is.
Otherwise, someone who has more knowledge of these cars than I do will hopefully post up and give some more advice.

Run a compression check on all of the cylinders. Hopefully it wasn't a valve bending or braking off and maybe have put a hole in a piston.
If there is an AutoZone store nearby, they will have compression tester for rent. You put down a deposit and when you bring it back in good condition, you get the deposit back.
Good luck!!

Pull the pushrods. Roll each one across a flat surface like a large mirror. Most likely one is bent. They usually bend before valves do so that's where you start looking. Easy to change too.
This is exactly why I always say use stock pushrods with big cams. They are a weak link and should be left in place instead of hardened rods.

PTV and Bent a valve/pushrod most likely.
