I know that someone has a 351W and Jag IFS setup but can't remember who it was...I am curious to know what was done to cure the interference issues that I am facing. I have been on borgeson's website and I know that stuff can be bought, but first wanted to see what headers or exhaust manifolds are being used. I have a pair of ceramicoat shorty headers for a mustang but my collector flange is in the way...bummer...so I put on the stock manifold and it has the same problem...bummer again...I thought about using an offset mid shaft but thats a bit pricey. I will do that if I have no other choice, but wanted to find another person with the same issue. Also I thought about offseting the 351W to the passenger side a bit but then it gets tight on that side.
I don't have any engine mounts yet and won't until I figure this out. Thanks! Jeff

 

Jeff,
Look at the log style manifold with the rear dump. That will get you away from the pinion on the Jag.

 

Okay what years are we talkin? what vehicles I assume older ones?
Thank you sir! were these available on a 302 also?

 

Jeff,
I am not the go to guy on sbf manifolds. My f-1 with the Jag IFS is set up with a sbc. That said however, if you google 351 ford exhaust manifold you will see what I call the "log" style, with a rear exit. They were used on trucks and vans in the mid 90's. They were also used on 302's. I am not personnally aware of which specific log style will give you the best flow/performance for your engine. Hopefully others on this forum can help more.

 

hey thats cool...I will do just that...thanks again! I hope its that easy, just a diff manifold.

 

Sorry Jeff I can't help you there when it comes to which manifold to use, as I had custom extractors specially made up clear all the steering and other issues.

 

not sure but i think there are guys using the crown vic ifs on 57-60's
don't know how wide your frame is. Look at some pics in my albums.
I am struggling with the steering linkage header interference. I am using a 351W , a 302 is a little narrower and might be an easier choice for fit, but i will figure it out, just not experienced with altering so many things at one time. I wish there was a simple solution to this cause im tired of thinkin about it. I guess if it was easy then everyone would do it though.
I didn't want to spend a fortune on steering joints but that may be the answer.

 

what year jag and model will fit a fioo 1952 32 wide frame help thank for the help. I found a 1991 xj6 ?

 

Mine is a '79 I think up to '86. Maybe some other JAG IFS guys will chime in here! Welcome!

 

I have a 86 XJ6 .. some say to that year back. i believe that 46 Steel has a later one in the 90'S not sure . May be will come on board and fill us in.

Happy Veterans Day And Thanks for your Service!!

 

Sorry for the mistake .. He is 48 Steel not 46 and I believe he used a 80 model..He has a pretty good tech on it. I know there are other that have done the swap. I would get out the old tape and check it out.

 

I'm using an 80 xj6 Jag IFS and a 79 Ford 351M stroker. In my gallery if your interested.

I got your PM, I think "shelly ellison" is asking for help! My IFS is done and I am working on my wiring decisions..

 

Mine is from a 1984, series III xj6. The later models, after the series III, have a different crossmember and won't work. The later model is not a series IV, like you think it would. I think it's something like series 40, or xj40.
Now about my comment of not working, the series III is a proven match for our trucks. The later series has a similar crossmember, but not the same. It may not be the easy bolt in that the series III is, but with some mods it may work as well. I don't know if any one has tried it, but you may want to be the first!
