It looks to me like it's a brand-new!

With a LIST #: 0-8207

It is a carb TYPE: 1460

CFM: 600

STOCK JETTING: (Front) 622, (Rear) plate 134-39

STOCK POWER VALVE: 8.5

Type of Secondaries: Vacuum

I would suspect it will likely perform just fine on a stock-cammed, V-8.

I would be inclined NOT to 'go through' this carb, rather I'd just bolt it on and give it whirl!

You're not going to get a carb'd engine to start in cold weather (less than 25*F) as easy as an injected engine will....

I think your #0-8207 Holley has a bi-metal choke mechanism which has a fitting to attach a heat riser tube to it. If it does and you do attach one, then the choke will work better than it would without it.

My best advise regarding cold starting is to have a well-charged battery and HAVE PATIENCE.....pump the acellerator twice, hit the key and once the engine fires up, feather the accelerator while keeping the idle around 1000-1500 rpms. After about about a minute or three, the idle should settle down and idle at 800-1000 rpms, now you can hop out and let it idle / warm a bit more while you scrape the frost off the windows!

Thanks DCClark. You don't Know if those came stock on F250's, and what years?

 

Thanks for the carb info! Once I get around to swapping intakes, I will indeed just try the carb the way it is. If it doesn't work I can always rebuild it then.

I don't know if they ever came stock, but they look like these American Racing (AR62) Outlaw II's : WHEELS | American Racing

The tires seem to be very popular around from mid 80's to 90's.
