Is there an official torque value for tightening the lug nuts on the Cragar wheels?

75 to 100 pounds typically depending on who you talk to.
Thanks Bob.
The Ford Shop Manual states "70-115 ft.lbs." without any special call out for type of wheels; and this is to be expected as the torque value is relative to the fastener, which was (well should have been :-\ ) selected as applicable for that which they were intended to retain, and for that which they retain would be constructed to be applicable for the fastener being utilized (hopefully :-\ ).
Or something like that! ::)
Note that although not stated, this was/is most commonly practiced as a "dry" thread process (probably why there's such a wide range in the numbers); which I don't agree with; but that's an argument for another day. :)

So, about 90 pounds, on average.
Would that be the same for original Magnum 500's as well if the shop manual did not specify a wheel type?
Just a simple reminder to RE-TORQUE after a few miles of driving. This is simple and critical to insure no problems. I keep a small note pad with the car to document when this is done and the mileage.
The reason Ford says dry threads is to keep things consistent. As an example if 1 wheel is assembled with threads oiled, and another had anti-sieze on the threads there is a huge difference in applied torque. Clean/dry = simple.
Enjoy the road!!

Agreed completely on the "re-torque"; though this is actually less urgent as a concern on the stamped steel wheels vs. the alloy units; this by the engineered design more than the actual material. :)
As for the "keeping things consistent", your probably correct, in that apparently the advisors to Ford on the best procedures as to be outlined, are implying that the typical "tire & wheel jockey" is too lazy and/or ignorant to be capable of following the "best" procedure! Hence the greater than what otherwise would be expected range of "acceptable" torque values listed. :o
