Headers and Exhaust
Hey there,
I've recently happened upon a '77 f150. Only thing is, it has a 429. The exhaust manifold was broken and rewelded at some point in its life and is now splitting the weld and of course, exhaust leak. In the market to replace with headers and subsequent exhaust. It is 4wd so i need to account for that. Looking to go with 1.75" into 3" collector ( I like the deeper sounds ). Any advice on brands and their pros/ cons? Not looking to spend too much yet.

4wd headers for 429/460 arent cheap at all. Best thing to do is look em up, theres a ton of reviews on the few that are produced. If you find that you are going to stick with manifolds, I may have a set to pass along.

4wd matters, manual or auto trans matters. Duel front shocks....That truck never came out with a 429/460 in a 4wd until the 80's.
Inside the frame rail exit can be a giant PITA and have front d/s clearance and cross member clearance issues. Outside frame rail exit has its own challenges, but not as bad.
Shorties, block huggers can cage and cook a starter. So think heat shield. Have you priced a replacement exhaust manifold?

With this swap, we have one set of headers that match your specs. Those are the fenderwell exit Hedman HED-85650. These will work with 4WD, but only with an auto trans.
To make headers fit modifications are likely. This is especially true with engine swap headers. You can view the reviews on our site for these. You'll see 1st hand fitment notes from our customers.
