Great info on my thread about a similar deal. Some of the folks that responded to me would be worth talking to about it for more specific information.

The important thing to look for is that it is a Ford model Holley 94. Only the Ford models have the Loadamatic porting for the distributor. Other vehicles used Holley 94s but without the Loadamatic provisions. Look for a 7RT or 8RT casting mark, although an 8BA will also work.

Be careful when you buy a used one. Look at the top of the air horn where the air cleaner attaches. Make sure you have the correct carb/air cleaner combination

The correct truck carb and matching air cleaner have a unique mounting surface at the top of the air horn compared to the car versions. It's a more positive gripping system, presumably for the higher vibrations one might see in a truck application. Because of this, the shiny aftermarket air cleaners the vendors sell for flattys won't work on truck carbs. They're made to slip over the flatter sides of the air horn on the car carbs.

Truck carb


Car carb




Here's an original truck air cleaner on ebay, although imho his price tag is a bit steep. These typically sell for under $50.

That is really good info!!
so question, would it be better for me to spend the $300 for a 'ready to go' carb? Or buy a $50 one on ebay and rebuild it?
