Have a 1996 f150 4wd auto trans.I have a set of Heddman long tubes will they fit and how did did any of you get them to work? Need helpful advice thanks to all who answer.

 

Engine??? 302 or 351 vast difference between them as far as headers go.

best bet is to try them or take some measurements. There are many subtleties and you can almost count on dinging a few tubes or installing them with the header in one hand and the starter in the other hand. Same with the collectors...make a cardboard model and measure from there.

Hedman makes a ton of stuff today, and if you can get a model number, they can point you in a direction. If they are older, then for sure test them first.

best of luck
