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.
