Big Plans for a 85 CAMARO..starting with powerplant.

Sure. Later year TPI intakes need one bolt hole altered. Early ones will fit fine. Cannibalize a 5.0L or 5.7L system - they're the same except for the PROM and injectors, both of which you'll need to change to properly feed a 400. Use one from a Camaro or Firebird - not a Corvette because the EGR system is harder to hook up. I converted an '84 Firebird to TPI once. There were a few hangups, but overall it was much simpler than swapping an LT1 into a Jeep.
