1998 L29 Vortec 454 potential?

[pandatime]

Found a complete, running, 1998 454 vortec (L29?) out a chevy 3500 with computer and harness for $750. Thinking about replacing the pontiac 455 in my trans am with a fuel injected motor and was wondering about the power potential of these motors. Say if I put L92 heads, a moderate cam/lifter kit to broaden the powerband, and headers all through a th400... Figuring on using lsx conversion mounts and items... Will this work? what would it take...
