I'm just trying to gauge how many Lightning owners out there have done this mod. I understand what doing this mod will accomplish. I'm just trying to see if it would be worthwhile to do it...

I`ve never heard of this mod. Your link asks for a log-in

 

The Cobras with the 4V heads have cooling issues, we don't.

 

i did it while my motor was out. it may not help much, but it won't hurt either.

there are a couple pics in my gallery:

I think I may do it just for the hell of it. I'm gonna have the lower intake out anyway doing a little clean-up port work on the runners. I think I'm gonna use braided stainless hose though.

 

I read on the topic a while back. IMO if you are running very high boost, its not a bad thing to do but if you're below 15psi, I don't see a reason to do it.

Its a different issue for the Cobras though.

I wonder if Ford has addressed this issue on the GT-500 motor????

 

Let me switch gears here a little....

If I was going to gut my A/C and heater from the truck, what would be the preferred thing to do? Should I just run a hose from one side to the other with no outlet in the center of the hose? Or would I just plug the hole on the passenger side of the intake manifold and call it a day?

 

The heater hose lines dumb back into the motor at the back of the water pump. You would either have to cap everything, or how I would do it is do the cooling mod and just go from those hoses to the back of the water pump(just no more heater core)

BTW; mine has the cooling mod done to it........

 

What he ^ said! Run the line from the tee to the back of the water pump.

 

Thanks fellas!

 

SW,

Were you a part of the thread on 'another site' when JJ posted up that this mod is not beneficial for lightning owners?

 

Yup. I tend to agree with him. But I also agree with the people that say it can't hurt.

 

Spence I have a bunch of links at NHTOC stashed away on this very subject Sir..

 

My engine builder (Al Pepito) told me on 2V engines it wasn't necessary. On 4V, it's a good thing to do. Just popped out my 2 rear freeze plugs and threaded barbs a couple of weeks ago. I figure it's cheap insurance.
