Has anyone purchased Tri-Y headers for their car. I'm rebuilding my 289 and looking for headers. Most of the mustang magazines sell Tri-y. What is everyone installing on their cars.They seem to be mid priced headers. ???

Yeah, they are pretty common and usually an easy install. Unless all hades breaks loose and I find something different, I'm probably putting a nice ceramic coated set on my car when I decide to tear into the motor.

If your car has a manual tranny you need to confirm the headers will fit with the factory equalizer bar or swap to a cable/hydraulic clutch.

I think most will clear a stock Eq. bar, but be doubly careful about cable clutch. Many headers are problematic with them.
Ask me how I know.

Hi, I've got a stock 289 2V with a factory T-10. I installed non-ceramic Patriot tri-y's a few years ago. They work great with my motor. They cleared my equalizer bar with no problem. I suggest you use copper gaskets instead of the paper ones that come with the pipes. It's worth the the extra $ for no leaks. All in all it was an easy install. You can PM me with any specific questions.

I remember the following things from the install.
- I installed the headers from underneath the car.
- I removed the valve covers to get easier access to the bolts
- I had to remove the equalizer bar in order to install the left header.
- I had to remove the starter to install the right header. BUT the old starter wouldn't clear the header. So I had to switch to a hi-torque mini starter. You might want to budget an additional $75-$100 for one.
