351 W in 65 Comet
351 W in 65 Comet
So after pulling my hair out with my new purchase the 289 aod combo is not working out. I am going to pull it back apart and i believe i will install a 351 windsor that i have. car has headman shorty headers but windsor id wider an taller so my question is any one find headers that work for this. does a 65 mustang have same engine bay as our comets?

Re: 351 W in 65 Comet
Not exactly, the Mustang is wider a bit IIRC. I don't think much wider but someone will chime in with the correct info soon, and I don't think it is over a couple of inches.
That being said, I am sure a lot of Mustang stuff will fit fine.
See Ya,
Mike

Re: 351 W in 65 Comet
My first 65 Comet was a 289 4-speed. I bought a set of headers from a friend who had a 65 Mustang 289 4-speed, and I could NOT get those headers to fit. That's been nearly 50 years ago now, but it seems I had problems with them clearing the front frame rails. A different make/model header for a 65 Mustang might have worked, but that set certainly wouldn't.

Ya, the Mustang drag link is +/- 1.5 inches longer than a Comets and it mounts to the inside of the frame rail so you lose space there so most likely all the way up. I think I read that the Mustang engine bay is longer too.

A friend of mine has a 66 fastback think ill go measure it up this aft. I already had interference between the pitman arm and exaust pipe on turns so im guessing it wont be easy. i can lower the engine if i buy a smaller fan or go electric that would also help trans clearance at cross member. i have seen several comets for sale with 408 strokers i wonder what they did.
Re: 351 W in 65 Comet
back in the early 90's when I converted to a 4spd,I found that STANG headers wouldn't work,,,,we found an ad in a magazine of a place 100 miles north of SAN FRISCO ,CALF,,called RED'S HEADERS INC..I called him and he built me a pair of tri-y's...and shipped them to me,,,as they were custom built for my 64 ,,I still had to take a ball peen hammer and touch one up to clear the idler arm...I think RED's has passed away and don't know if his place is gone or still around...WE have a 351 in a 64 comet..but it has a rod/custom frt end,,we used a set of headers for a 94 stang,and still had to notch the frame slightly on pass side....and we have ford's N head so the flanges had to me modified some to bolt up....none of this helps am sure,but it might !!!!!! good luck...………….pop

Re: 351 W in 65 Comet
I would bet hand built headers. Lots of those 408s would have
custom heads to boot so cut a pair of flanges and a pocket full
of mandrel bends, away ya go!
If it were easy everybody would be doing it.

Re: 351 W in 65 Comet
They do make headers that fit. Higher end brand and the name escapes me but most also notch the shock tower. I have been told the shorty headers don't work. The headers in my 65 comet 302 block are old (from the 80s) Headman 351W for a 66/67 fairlane but I had to modify them a bit. If you search way Back and probably in the 65 comet forum.I know Roy answered this question a couple times.
Reread a bunch of posts. 289/302 Hooker Super comps. Roy ended up making his own when he switched to a 351W. Kooks is the one I thought made headers for what ever block and head you have.

This company may be able to come up with a header that will fit the application without cutting in the car.

I am using a vintage set of JR Headers on the Cyclone, the owner of Mad Dog was associated with JR when I purchased my set.
