How big of an engine could I put in a 1994 Firebird?

[Bill]

All i care about is finding a bigger engine than I have which in the bird I have is a 3.4L v6. I was wondering if it is possible at all to fit a bigger engine in it.
Money is not an object. I have enough to get it completely fixed up nice

A 455 will fit

possibly a v8 thats the size from that yr that was in the trans am might fit

Most any GM engine will fit in . There might be a fair amount of work and expence
