1966 f350 headers ?

I have a 1966 f350 with a 390 . I contacted summit racing and they show none for a f350. There was a comment on the headers I wanted that stated will not work because of the different steering box . Any pointers would be greatly appreciated

I don't play with the 350 arena, is yours a side mount or front mount engine? Is it a straight axle or I-beam?

A set for a '66 F250 4X4 should work as the frames and steering boxes are very similar. I run a set of THESE and they fit great.

It's a front mount as all 240/300/352: 1965 F100/250 4WD, 1965/66 F350, 1966 F250 4WD use the same engine mounting system as 1961/64's.

F350's didn't have Twin-I-Beam front suspension until 1967.

btw: There will be no applications for a 390 engine in any 1965/67 F100/350...since the 390 was introduced in 1968 F100/350's.

The only V8 available 1965/67: 352 2V

And, does the OP's truck really have a 390? On sale day, 352's magically become 390's!

It's a front engine mount and a straight I-beam front axle , and what make of headers are they ? My steering shaft pretty much goes through the floor not the flat fire wall too. I've never seen a 4x4 f250 so I'll take your word on it . I believe it uses a gremmer steering box , I'd like to add power steering but that will be later on .

I believe it uses a Gemmer steering box. I'd like to add power steering but that will be later on .
1961/64 F100/350; 1965 F100/250 4WD; 1965/66 F350; 1966 F250 4WD: The steering shaft goes directly into the steering gearbox.

Once the A/T (2WD only) or 3 M/T shift linkage (if so equipped) is disconnected from the column, the pitman arm is disconnected from the steering gearbox, the column and gearbox are removed as a one piece assembly.

Steering gearbox is the same: 1963/65 F100/250 4WD; 1965/66 F350; 1966 F250 4WD

F350's prior to 1967: No P/S can be swapped in from any other year Ford truck, so you'll have to buy an expensive aftermarket P/S kit.

btw: In 1941, Packard erected a new building on the north side of their assembly plant to assemble Rolls Royce-Merlin V12 aircraft engines, initially for the Brits.

After the war ended, Gemmer purchased this building. When Gemmer moved elsewhere, the plant stood empty until it was purchased recently by a Detroit firm that stages special events.
