i'd go to summitracing.com an see if any are listed. if thats the engine that originally came in the truck somebody out there makes a set. I got mine from summit, hooker supercomp and i love them. 1 3/4 primarys 3" collector. bout all thats avalible for a 351m, but i could be wrong. some other companies i know of are blackjack, hedman, summit, flowtech. Hope this helps, i know i had trouble finding a good set for my 400 when i built it

I bought a 77 crew cab 4x4 w/ 351M and the prior owner had installed a set of headers, I will try to check when I get a chance to see what brand they are, there was a tag on them, I just can't remember what it said

I have not found any yet, but still looking. Hopefully someone that has installed a set will chime in. If I do find a set and they work I will be sure to let you know. Thanks

I posted on the old thread that fordmuddin brought back..... I've got a perfectly original (except for headers) 77 highboy that I bought recently. The previous owner had just put them on, I want this truck all stock. I will trade these headers even up for the correct manifolds.

My truck is completely original, I dont know how good they will be when I remove them. They are almost 33 years old. I dont know if you would want them. I would be interested in yours, either buy them or if you could tell me the manufactor and numbers. Thanks

the highboy is from the factory 4" higher than the other models. (4" blocks standard in the rear and more leaf springs in the front with more arch) the truck also has a lower hanging divorced transfercase with a longer or equally long front driveshaft as the rear driveshaft. The highboys have the tank in the back of the cab so the gas cap is located high on the cab. along with varius other differences but you get the point. The engines available were the 360FE, 351m, 400m and that may be all, not sure, maybe others but i know that no 460's, 429's, or 390's would come standard on the highboys.
