Headers up or down

I feel everyone is entitled to a dum question every now and then, so here's mine.

On a 351C with auto trans, do you install headers from the top and down or from the bottom and up. 50/50 chance?

I had to install the passenger side from the bottom . Drivers side went in fine from the top.

Set mine in place before the motor went in

Had to install both of mine from the bottom. Roy how did you clear the cross member? I might try that whenever I get my engine back.

Set them in loose first then set engine in

The passenger side is the easy one, the drivers side depends on manufacture and clearance.

You may have to disconnect the pitman arm from the cross bar on the steering and install it from underneath.

If you are removing the original exhaust manifolds you will need to pop the steering joint and get the bar out of the way for clearance

brand and length probably are a factor.

Hooker super comps. Passenger side from the bottom. Driver side from the bottom BUT I had to jack the side of the car up pretty darn high. I tried from the top and that didn't work.

351 2V, power steering, FMX

I installed Hooker Comp headers(1 3/4 tubes) from the bottom. Only had to raise the car enough to get enough room to angle the collectors. This was the easiest Header install I have ever done on a Mustang. My other efforts were on a 67 390 (the worst), 69 428 (not as hard as it seems if you remove the motor mounts) 5.0 fox and a 65-289.

Something like this Damián?

Ford 250 inline six header



Just kidding, I know you are a factory stock kind of guy like me.

I had clearance issues with mine hitting the power steering box on the drivers side, so I had to switch to the taller motor mounts for a convertible to raise the engine up a hair. I think I got both of mine in from the bottom.

Jejej!! All shinny chrome ehh!!? could work!

Not my style you´re right ... I´m not that far of working in my exhaust... I listen a little leak there and i´m pretty sure my car is runnung with an Argentininan made piece there!!... just have to look in the bottom and see if it says "hecho en Argentina" or not ... the rest is excatly the same...

To be useful to this thread, i think that the best is trying to put everything together outside and then, carefully put the engine in its place... Even changing sparkplugs can be complicated in wide V8 engines...

Hooks are on it...Passnger side was easy, slide right up from under and plenty of room. Drivers side was tight. Even getting out the stock manifold. Pulled the PS pump and worked her up from under. Now need to cut pipe from where PO added a section when he removed headers. Good part is the center pipe is the correct length so they will line up fine. Then just need to take to exhaust shop to weld collectors to pipes.
