since they are both 90* V6 all mounts and accessories transfer over. Running tbi with a fuelinjectionconnection.com harness and astro sending pump unit means you can have it done in a weekend.Tons of work and you'll likely be underwhelmed with the end result. Swap parts like exhaust are significantly more difficult to source than V8 stuff. Also there is far more support for wiring/ecm changes with more common swaps. Don't get me wrong, the 4.3 is a decent engine, I just question the reward/work equation.
