timing chain and cam

I have a '92 firebird with a 305. How do i figure out if i have a hydraulic roller engine or a non hydraulic roller engine?

Also what is a good cam to upgrade the engine with that is stock?

Thanks

If it's the factory engine, it's a roller cam.

Yes it is factory, so it is the hydraulic roller engine. AWESOME thanks. Any ideas on a good cam to put into the engine?

Someone else could probably suggest something. TBI or TPI?

It is a TBI motor. I was told i could upgrade to a bigger TBI from a 454 motor that is a 670 cfm.

You might get more help about that kind of thing over on the TBI board.
