I got sick and tired of the leaking stamped valve covers on my 460. (And don’t give me a lot of hooey about tightening them down too tight. I am not an idiot) So I decided to try and find some die cast aluminum valve covers with the thick mating surface. The only problem is they make hundreds of them for Chevys but not Fords. I was able to find some but they are all tall for high lift cams and lifters. I bought a set and was able to put the one on the passenger side and stopped the leaking but can’t put the one on the driver’s side because of that 12-inch diameter single diaphragm brake booster hitting the valve cover. I decided to just put a F350 dual 8-inch in diameter diaphragm booster on and that would give me the clearance. The only problem is there are none in existence. I checked the marketplace on here and can’t find any. Does anybody have an idea where I could go to find one? I have checked the boneyards around here and they don’t even have any early Ford trucks. (Lots of Chevys but no Fords)

1973/79: 1976 F350 was the only year to have an 8.80" diameter booster. 1973/75 F350 is 11.18" .. 1977/78 and 1979 F350 2WD is 9.38" .. 1979 F350 4WD is 11.00."
All these boosters are obsolete from Ford, only chance of getting a replacement is from auto parts stores.
You need to speak with FTE member ultraranger .. he's the one who knows what F350 booster to use.
Look at Cardone #54-73311 for a '78 model short push rod booster (and part #54-73350 is the '79 model long push rod booster). Advance shows it available still.
I used Cardone #503311 which got me a Booster&Master Cylinder combo for my brake upgrade on my '77. It is a dual 9-1/4" diaphragm booster up on a bellcrank/bracket. I had information that my OEM master cyl with lines towards engine had a narrower bolt pattern than the F350 one … that works with increased piston diameter, and it fit booster which it came attached to, lines come out on fender side. Also still available. Not a lot more $$$ either.
Wait for it, either way you likely will get a 25% discount offer if order on internet, then measure MC mounting bolts width to make sure when you go to pickup. https://shop.advanceautoparts.com/p/...E&gclsrc=aw.ds
I also used larger pistoned T-bird calipers which have piston area virtually same as dual piston F350 calipers, and I used F-350 rear wheel cylinders which all go great with larger bore F-350 MC.
Which calipers on your F-250, single or dual piston? I know your's is a F-250, but there may be something in my brake upgrade that might help you.

I've never heard the wheel cylinders had bigger bores in a F-350. When I put the Dana 70-U under my truck, I was at the parts store getting brake shoes and stuff and I had them look up the wheel cylinders. The guy told me they were the same, so I just put my old ones back in. Maybe Bill will come along with some imfo on that ?

They look same, bolt on same, but larger pistons inside amplify psi from lines. Since I had used a F350 MC with bigger 1-1/16" bore (stock F150 has 1.00" bore so F-150MC is 1.13 X as great) which moved more volume each pump, I wanted to make use of the increased line pressure/volume afforded by the F350 MC/Booster combo without applying rear brakes too soon ahead of fronts. F-350 WCs are 1-1/16" diameter (0.88667squ"), F-150 were 15/16" (0.69031squ") stock … that increase in area alone gets 1.28 times the force for same line pressure, but also uses more volume each application which I figured was a good match for larger MC bore and larger front caliper pistons.
In hindsight, I probably would have gotten a slightly better matchup using 1" diameter (0.78542 squ") RWCs. Then the increase would have been 1.13 as great which more nearly matches the increase in front caliper sizes (up from 6.48 squ inches to 7.51 squ inches = 1.1589 X increase). As it is, I delayed rears but increased force once applied. I doubt if I could tell much difference … but then she will squawl the rears a little if used hard.

1 1/16" rear wheel cylinders: 1973/75 F250 with 12" x 2 1/2" brakes, 1973/79 F350 with 12" x 3" brakes.
1.00" rear wheel cylinders: 1976/79 F250 with 12" x 2 1/2" brakes, 1979 F350 4WD with 12" x 2 1/2" brakes. These F350 4WD's also have a Dana 60 rear axle.
I wonder why the jerk told me that... Glad he doesn't work there anymore, I would have bought them, they don't cost much. I'll switch them next time I'm in there working on the brakes.

Not a '77 F250, mine is a F150 … but cab metal and etc same. I used F350 parts to upgrade my brakes, which were same as some lighter GVWW F250s. A lot of, nearly all ... that I did would work as well on a F250.
You might be able to do same with your '76, but first do some comparisons of part numbers for F250s and F350s online at like Rock Auto. I think you'll find same info applies.
