Texas T/A

Just had a Vortec 350 rebuilt and planning to drop it in my 92 Trans Am convertible. I know I have to upgrade to 350 computer/chip,injectors,sensors,etc. Have a few questions, I'm keeping the TPI setup and getting a TPI/Vortec intake (not sure which one yet). My questions are, which waterpump do I use? which distributor? What headers will work with the vortec? flexplate? and finally, will the original auto transmission bolt on?

Waterpump will depend on the accessory set up you use. If you are using an 87+ serpentine setup you'll need a stock reverse-rotation waterpump. Basically any 87+ water pump for a 350 will work.

Flexplate - Any Flexplate from a 1-piece RMS F-body will work(87-92)

Headers - Any standard SBC headers for an F-body will bolt up

Transmission - If your bird was originally a V8, then the transmission will bolt right up. If you had a V6 in there however, you will need to replace it with a V8 transmission.

Distributor - I believe a regular 87+ computer-controlled V8 F-body distributor will work, but I'm not 100% sure of that.

If your Trans Am had a V8 in it originally, then the flexplate, exhaust, water pump, and starter can all be used on the Vortec block. The distributor I'm not 100% sure of as I said, but I believe it can. The only differences between a Vortec block and an older SBC are the intake bolt pattern, it uses a roller cam, and the rear main seal is a 1-piece.
