Hi Guys,
I have a pretty mint ED Fairmont wagon. The 4.0 is perfect and the car has only done 169,000k's but I think it needs the V8 to finish it. In fact if I ordered it new the only things I would change would be to option the V8 engine and choose Cobolt blue.
Anyway my questions are;
Whats needed to fit a 5.0 to a 4.0ED?
Does the A/C, P/S and alternator fit or are the V8 bits needed?
Will the 4.0 trans fit up or will I need the V8 trans?
Does the tailshaft need modding?
Will the fuel pump from the 6 be okay with the 8?
I want to keep everything else stock, so it looks like a stock 5.0 Fairmont wagon.
I have fitted clear lights and Kings super lows in the front and 2" blocks in the back but have retained all the perfect condition stock parts.

Thanks in advance,

Jason

I'll feild some of these:

1) the Air conditioning, power steering and alternator need to be V8 items, and you'll also need the V8 power steering lines.
2) You will need to source a V8 Transmission
3) Your original tailshaft is the correct length, and you can use it no dramas.
4) The fuel pump will be fine for the V8.

I'll add a few more things.

* The K frame will need to be swapped for a V8 item.
* You'll need to source all the wiring looms, the ECU, and the transmission computer from a V8 vehicle.
* Obvously your exhaust will need modding, but if you have a 2.5" system already, you can probably re use most of it, as long as it's not crap.
* Your tacho will NOT be calibrated for an 8 cylinder engine, 3 options, get a gauge specialist to re calibrate yours, have a go at recalibrating it yourself, or fit an instrument cluster from a V8 car.

Everything else is pretty straight forward. The easiest way is to get a donor car and swap everything over. a Sedan would be fine too, NC Fairlanes are often cheap on ebay with V8's, and that'd have the added bonus of giving u a nice Interior.

Cheers for the quick reply's guys.
I was kinda hoping it was like my old XA that we modded from a 200ci to 351ci years ago and all we needed was the engine and an exhaust, lol But I guess the air, power steer and ecu make it a bit more complicated

I like the idea of a complete donor car but love my interior. I hate plastic wood grain and leather, thats why I don't own a Ghia, lol

hi guys new to here but i have just done this conversion all i can say 17 hours work well worth it BUT i would never of done this without the donor car (nc fairlane) after getting the k frame and bent 8 in(all together from underneath!) and start plugging stuff in to find i needed to change the whole engine bay loom over due to the v8 having its own comp !
