So I dug up this computer controlled cam that's supposed to be stock computer compatible. Any cam experts out here that can give opinions on the specs vs what was stock in the 1995 454 SS TBI? I'm running 32PSI fuel pressure but could up it a little bit if needed to compensate for the cam.

94 was the last year for the 454SS so I'm not really sure what you have.

210°/215° @ .050 and .500/.500 is really small by big block standards. I'm not sure what stock was but it can't be much smaller. I am running a 229°/235° @.050 .589/.601 and it is not high strung by any means. I still pull a trailer with it.
