I have a 1976 F150 4x4. I'm trying to figure out if the truck has been lifted. I bought the truck in Montana while working there and then drove it back to Denver. I never did much looking at it though. It has 33 inch tires on it and there is an air bag leveler on the back springs. There is also a block under the springs on the axle. I haven't measured the block but it appears to be 4 inches or so. I just wondered if there were originally blocks on the 76 f150 or if anyone knows the length of the coils up front. The truck also has a 460 in it if that means anything. Manual transmission 4 speed. I believe Dana 44 front end and not sure on the back. Maybe 9 inch or 44 not sure.
Well, even the half tons had blocks under the springs from the factory. A stock truck will also clear 33's. Do the blocks have "ears" that stick out towards the inside? If they do, that's factory. They're for the bump stops mounted on the frame.
The 460 is more than likely NOT stock because I'm not sure if they came with 460's that early. (I'm sure someone will correct me if I'm wrong) If the rears are stock, you have a Dana 44 in the front and a 9" in the back.
Moonley is right, Only F-250's were highboys and they had a divorce-mounted transfer case. (the truck has a standard 2wd transmission and a short driveshaft connecting the trans to the transfer case) A stock dent side Ford sits a LOT higher than a 4wd Chevy Dodge of the same year. A picture will help to nail it down, but with the information listed, you may or may not have a lifted truck.
I'm virtually certain you couldn't get a 460 in a '73-'79 4x4 from the factory. The largest displacement engine available was the 400, and that was in the later years.
There was a slight difference in the 4wd vs 2wd 4-speeds. The tailstock housing on the 4wd versions had a boss cast into the side that was drilled and tapped for mounting the transfer case shift lever to.
