If you want to keep the fuel injection I would do a 411 PCM swap. Google it. The early PCM's are difficult to flash. You have to remove the PASS KEY security stuff from the PCM program & turn off the rear O2's. I've done the 4.3 vortec/5 speed swap in a Luv truck. Its not a bad project if your decent at wiring.

You can save a lot of headache & heartache by buying an intake/carb/distrbutor/electric fuel pump.

Let me know if I can help.
