pertronix thats were mine come from i got mine installed and the pitman harm hits the headers i know i posted it before but i hate to take these off and use the old one but it don't sterr to the left much at all too much to dent the headers i was told to use 66 moter mounts that would help does anyone know about that ?? some one give me some input please !!!

Iv heard quite a few people have the same problems with Tri Y's. Some of them just loose'end the motor mounts and shifted the engine a little and thats all they needed. As for the different motor mounts . Got me? Im assuming the 67's sit the motor a little higher or something.

The 66s had taller motor mounts. I think it sits about an 1/2 higher or something like that. Do you have power sterring, if so you can buy a drop bracket.

 

[Cobain03]

i did the drop bracket,, that no the problem the problem is the pitman arm hits the header pipe when going to the left

Yeah you should switch to the 66 mounts, they are taller and give you the right amount of clearance.

 

[Cobain03]

are you saying this form experiance or from what seems right?

 

[jb1dsl]

i have a 66 but my buddy has a 64 1/2 and when he put his jba headers on they nade contact with stuff. he changed to later model mounts and it gave him more clearance

 

[Cobain03]

i guess im gonna have to try em. how much higher did the engine sit? is jacking up the tranny required as well so it balances out?

 

[blue66tang]

No,

Depending on how much hieght you need but I put a large body shim between the motor mount and the frame mount and it solved my problem.

 

[Cobain03]

i did shims at first to rasie the motor to help clear the headers from the fender well and other things but still didn't help the pitman arm ,, i think i should have used shortys insted i guess

Give them a call.

well i call them and spoke to a rep. and basicely he said there was some mods that come with every set of headers( that is bull ) if i know that i wouldn't have doen them i thought they bolt up really so i don't know maybe time to put the old ones back on i guess take a lose can't drive this way ( away to the left lol )
thanks guys for al the help i knew you all would know alot about this as always thanks again

Hooker super comps is the way to go. In my opinion at least. I never had a single problem with them, they fit perfect and look good.

 

[Cobain03]

how did they clear the pitman arm??

 

[blascrw]

unique

You may have some unique problem...

Tri-y's have been around as long as mustangs have and you don't hear of too many problems...

Mine fit perfectly...so have others...and the same goes for any other brand...

so I wish I could be more help...you may find the same problem with a different brand as you have now...

[Cobain03]

well i think its time for e-bay and back to the orig i guess

 

[blue66tang]

how did they clear the pitman arm??

I have absolutely no clearence issues. Well i take that back i am using a lakewood scatter sheild for a late model mustang, so i had to put a small ding in one of the pipes. Not enough to cause any real flow loss. But when i had the old bellhousing in it fit perfect.

 

[Cobain03]

but my problem is pitman arm i don't think a small dent will help i will more this weekeend

I'm pretty sure the headers are not your problem. Like others have said, they've been making tri-y's for mustangs for 40 years, they were designed to fit the mustang chassis specifically. I have tri-y's and have zero problems whatsoever. In fact, I used the tri-y's because I knew they would fit right. It kinda sounds like your pitman arm has been improperly installed to the steering box, like maybe it was installed off-center. If its a few teeth off, the travel of the pitman arm will interfere with other components. Take this into consideration when/if you try another set of headers because they too may also not fit properly.
