I'm ready to drop a 351 Windsor into a 67 Mustang convertible with a T-5 and don't know what headers are going to fit ....I've also lowered the car 1" all around

Hedman (sp?) makes a nice full length header for a 351 swap into the 65-70 body - including provisions for running a 4 speed. In your case, the T5 will make it that much easier if you go the cable or hydraulic clutch route. JBA also makes a short header, but much more pricey than the Hedman unit.....

Since the 390/428 was factory available, there is plenty of room for other aftermarket headers include Hooker, Doug, and so on. Go with something that fits your budget and performance needs....

As Randy pointed out the 67/8s came with 390/428s as options so the room is there. In fact the room is similar to the 69/70s so you could basically use a '69/70 set of 351W headers I bet. I have the Hedman swap headers and I dislike them for a couple reasons:

1.) Not necessary on a 67/8
2.) The primaries on the driver side are all over the place, one comes up above the valve cover lip and makes things a pain to work with.
3.) The collectors are garbage and bend all up on install and do not "point" at a very good angle.
4.) Price is high since they are a "custom swap part"

Get a set of Hookers or if you want to go with shorties then JBA is the way.

I'm using Hedman Shorty 351swap headers on the Clone Vert.They're Jet Hot Coated. They also make a full length swap specific header as Bossman says.
I went with the shorties because of the AOD tranny and the Lower Global West suspension.

My 67 convertible has a 351W and toploader. The 67 convertibles have a unique motor mount, note the part number.

I tried Hedman long and short headers, cast iron hypo headers, and JBA shorty headers. The JBA's worked but left a very small clearence with the steering box; this left a sometimes annoying rattle or knock between the two. The second part of my solution was a set of TCP motor mounts. It was also necessary to wind the exhaust tubing around the toploader z-bar/clutch linkage.

Hope this helps.

I have a set of used Hooker Super Comps, p/n 6116, that are for the 351W in '67 stangs. They are in really good condition. If you're interested drop me a pm.

I looked up on net and it looks like you're bang on. You don't have any problems with the steering box? Heddman have a set but I'm leary of paying too little for something that really counts .
What did you pay for your set?
Thanks again

Thanks for your imput, I'm really impressed with all you guy's taking the time to answer my post. I haven't heard great things about Heddman. Hooker super comps seam to have a good rep.
How pricey are are JBA 's ? The 351 I've had done will be pushing 400 HP.....


Thanks again

Whatever headers you use, make sure the header flange is extra thick; my experience is thin flanges (like Hedman) tend to get exhaust leaks. I like shorty headers because they avoid power steering ram drop; a work around item that causes chassis flex and even more "loosey-goosey" steering.
