My father recently gave me my grandfathers 1975 F 150 Ranger. The truck sat for about 15 years. I restored the motor and it started right away. A/C and heater even work great. Only problem is when we started it we noticed that it was leaking gas from the gasket under the carb spacer. When we removed the spacer we found that it had deteriorated. The only part on the truck that did so. My problem is that I haven't been able to locate a spacer to match. The spacer has a protrusion from one side that covers a hole, and this is where it deteriorated. I don't know much about mechanics. LOL! I am learning. As far as I know it's the original carb. It's a 7.5L 460/4 brrl. If anyone can help I'd surely appreciate it. This is the only thing holding me up. Here's a link to a picture of the spacer i'm trying to find.

The factory spacer has an exhaust passage for the egr valve. Aftermarket spacers and intakes do not have provisions for the egr valve, and therefore do not have that passage.

 

Thanks bud! So where would you suggest I go to get one?

 

Is that a spread bore spacer like a GM ? I never new ford used them,but then I don't claim to know everything. It's not anything like the one on my 460.

 

Its not a spread bore, just the secondaries are that big. I think the ones i have the secondaries are about the same size as the primaries. Also, yours did not look it had the egr on it. I would suggest talking to your buddies that are building 460s. They more than likely would be putting on aftermarket intakes and not using the spacer, so they might have them laying around. or salvage yards.

 

That's considered a spread bore spacer

on a square bore ..all the holes are the same size

 

I thought it was spread bore ,I have a couple of each and that kind was listed as spread bore.

 

Yes, it's a spread bore carb, a Motorcraft 4350 to be precise.The later square bore spacers were produced with cast iron, as the original aluminum spacers would eventually melt like Trevor's

I recently changed mine to a Holley square bore, and have the original adapter available if you still need it Trevor. It's off my '76, and has about 65k miles on it, so it hasn't melted yet. I picked up a square bore manifold and spacer at a local pick-n-pull wrecking yard for about $50.

If you have not found one yet I have one that looks almost new if you're still needing one..
