Rpo 83 Xa

After reading the thread on the Phase 4 falcons I was wondering if anyone has any specs on the RPO83 option. The bloke down the road has one in his shed and it looks like stock low km XA GT .
However it wont idle below about 800 RPM and obviously has a very different cam from a standard XA GT.
I believe that the engine is how it was supplied from Ford.
Any info anyone?

the cam was supposed to be a stock XA GT cam.. it was breathing mods like extractors and the holley that gave it the extra grunt

"When it became apparant the Phase IV was stillborn some of the smarties at FoMoCo decided to tip the hot parts already produced into regular Gts. This option was called RPO83"

Basically
780 Holley had a manual choke - idle 800, fast idle 2800. 8000rpm tacho, extractors (same as phase 111) modyfied sump (with baffles) and in some cases - Rear discs (from the LTD)

That info is from my magazine "History of the Falcon GT"

hope it helps

RPO83

I own a very low mileage (23,000) RPO83 coupe. The main differences according to Ford was the 780 Holley (as per Phase 3 and 4) and the H & M Headers, which were different slightly to the Phase 3. I know of about 20 others and only 1 of those supposedly has rear discs - so I'm told. The sump had additional baffles, but it wasn't a Phase 4 sump - no ears. But Ford did do some funny things, and there were a supply of parts for the Phase 4's that were never built, so they had to go somewhere, so who knows???

All I can say is - in the words of Monty Python "You Lucky Lucky Barrstard"
