Hooker 6921HKR Competition Headers

[Jean-Pierre]

Hi.

Can someone tell me if this equipment can be installed on a 73 351C 2V with power steering and an FMX automatic gearbox ?

Has any of you done it ?

Some sites say yes and others not because of power steering or automatic transmission...

Hi

How much is clearence with theese ?

 

[Jean-Pierre]

Sorry, I don't understand...

I want to put the ram air on my 2V and change the header by better to improve intake and exhaust in my engine.

Like that, it will breathe better...

These fit fine on any 71-73 Mustang/Cougar. The power steering issue is for the 70-71 Fairlane/Montego since they have the external ram for power assist and require a drop bracket like the 65-70 Mustangs. See catalog snippet below and catalog PDF from '07. Ever since Holley bought out Hooker, their tech and website has been complete crap.

Footnotes:

4 - note about using Hooker products to fab exhaust

29- 2V heads only

33- 4V heads only

226 - fits w/C-6 auto

I have them in my car with FMX and they work and have good clearance, mine are for 4V heads, but I don't think that matters. Good luck!!

 

[Jean-Pierre]

Ok, fine.

Thank you to all of you.  I will be to get to work... ::thumb::

Hi Hemmykiller

You are sure?

4 - note about using Hooker products to fab exhaust

29- 2V heads only

33- 4V heads only

226 - fits w/C-6 auto

Because in the site I would like to buy, it is not exactly that.

The Hooker 6915HKR with 4,29,226 is for 4V heads.

And the Hooker 6921HKR with 4,33 is for 2V heads.

You will see on the site that I asked the question for the power steering and the answer is negative. I'm a little lost...

Omie01 : for the 4V, he doesn't talk about the power steering... 

:huh: :huh: :huh:

I'm not entirely sure what the question is here, but the Hooker Competition 351C-2V headers fit with factory power steering and FMX just fine (I installed an AOD, but the FMX has a smaller valve-body/pan, so FMX will certainly fit).

Mine are ceramic-coated, BTW - but the same model nonetheless.

The exhaust is Pypes 2.5" stainless with X-pipe.  The collector flanges are Hooker units, and also come in stainless (which I didn't know at the time).

Got everything from Summit Racing, cheaper than CJPP.

Hope this helps!

 

[Hemikiller]

Yup, I screwed that one up on the footnotes.

6915 - 4v

6921 - 2V

The answer "RK CJPP" gave you directly contradicts the question below yours, the Hooker catalog and my (and many others here) personal experience.

To be clear - there is no issue with these headers in a 71-73 351C Mustang with power steering.

 

[Jean-Pierre]

Ok. Thank you both for your answers. This is clear enough for me and it take away the last doubts. ::thumb::

And, Mister 4x4, very nice chassis end engine view from below...

I only have to find a new exhaust that goes well with to replace my old tubes. A nice sound and better exit of gases.

Do you have any ideas ?... :whistling:

 

[Robsweden]

Great info thanks
