1970 XR7 convertible engine bay

Hi everyone,

I am giving my engine bay a bit of a cleanup. I am not aiming for show quality or anything, I just want it to look a little nicer when the hood comes up (and not so much like the engine bay in the Ford given to Will Hunting at the end of the movie).

Attached is my ‘before’ picture.


So far, I have:

  1. Got new valve covers.
  2. Had the valve covers and the air filter housing resprayed Ford blue (or v close to it).
  3. Got a better oil filter cap (this one Oil Cap - Twist on - BLACK - Closed Emissions - Repro ~ 1968 - 1970 Mercury Cougar / 1968 - 1970 Ford Mustang ( 1968 Mercury Cougar, 1969 Mercury Cougar, 1970 Mercury Cougar, 1968 Ford Mustang, 1969 Ford Mustang, 1970 Ford Mustang ) at West Coast Classic Cougar :: The Definitive 1967 - 1973 Mercury Cougar Parts Source).
  4. Got some repro stickers for the air filter housing.

Here are my simple questions:

  1. Where does this go? Decal - Air Cleaner - Service Instruction - Repro ~ 1967 - 1973 Mercury Cougar / 1967 - 1973 Ford Mustang ( 1967 Mercury Cougar, 1968 Mercury Cougar, 1969 Mercury Cougar, 1970 Mercury Cougar, 1971 Mercury Cougar, 1972 Mercury Cougar, 1973 Mercury Cougar, 1967 Ford Mustang, 1968 Ford Mustang, 1969 Ford Mustang, 1970 Ford Mustang, 1971 Ford Mustang, 1972 Ford Mustang, 1973 Ford Mustang ) at West Coast Classic Cougar :: The Definitive 1967 - 1973 Mercury Cougar Parts Source
  2. Where does this go? Decal - Air Cleaner - FRONT of Air Cleaner Indicator - Repro ~ 1967 - 1973 Mercury Cougar / 1967 - 1973 Ford Mustang ( 1967 Mercury Cougar, 1968 Mercury Cougar, 1969 Mercury Cougar, 1970 Mercury Cougar, 1971 Mercury Cougar, 1972 Mercury Cougar, 1973 Mercury Cougar, 1967 Ford Mustang, 1968 Ford Mustang, 1969 Ford Mustang, 1970 Ford Mustang, 1971 Ford Mustang, 1972 Ford Mustang, 1973 Ford Mustang ) at West Coast Classic Cougar :: The Definitive 1967 - 1973 Mercury Cougar Parts Source
  3. What other decals do I need to make it look factory correct? There is a decal on the snorkel that I have not been able to find yet.

Here is my more challenging question. What air filter housing have I got? This is the mystery:

  1. The car came with a 351 2V. So far as I know, it still has it. The sticker for the lid that most people have is this one: Decal - Air Cleaner - 351-2V - Repro ~ 1969 - 1970 Mercury Cougar ( 1969 Mercury Cougar, 1970 Mercury Cougar ) at West Coast Classic Cougar :: The Definitive 1967 - 1973 Mercury Cougar Parts Source I have put a repro of the same onto mine.
  2. The sticker in the photo is one of these: Air Cleaner Decal - 429 4V CJ Non Ram Air - Repro ~ 1971 Mercury Cougar - 1971 Ford Mustang ( 1971 Mercury Cougar, 1971 Ford Mustang ) at West Coast Classic Cougar :: The Definitive 1967 - 1973 Mercury Cougar Parts Source or Air Cleaner Decal - 428 CJ - Repro ~ 1969 - 1970 Mercury Cougar ( 1969 Mercury Cougar, 1970 Mercury Cougar ) at West Coast Classic Cougar :: The Definitive 1967 - 1973 Mercury Cougar Parts Source It is hard to see from the photos, but you can just make out a 4 on the old sticker.
  3. Most 351 2V engines that I see have an outlet for a tube running to the oil cap that is at the front of the housing, just above the distributor. If you look in the photo, mine is on the side, just above the oil cap.
  4. I have a Holley carb.

Has someone stuck a 428 or 429 sticker on the old filter housing, or have I ended up with the case from another Mercury?

My other questions is this: what other simple things can I do to tidy up the engine bay?

I’m usually not very good at this game, but that doesn’t look like a 351 air cleaner to me.

It is a 1970 351W air cleaner with the exception of the decal. I’m not using the correct one on Ginger, but that is what it had when I bought her. The cowl should not be body color, but if you like it leave it, The fuel line is not correct, it has been trimmed back to add that in line filter. It this were mine, I’d pull off all the accessory’s and brackets and paint the front and top if the engine FORD Blue. The water pump should be painted.
This evening I’ll look and see if I can find a decent picture of a 70 351W engine bay. I am not sure what I have. But should have something that will help.

So the breather tube can be in either location? Or is that determined by something else? Every picture I’ve seen has it in the front on a 351W.

In addition to the above advice, I recommend getting a fan shroud. It’ll neaten things up, but more importantly, your car has the “standard cooling” radiator, and in my experience they’re barely adequate in hot weather. A shroud will help.
Also, please don’t use the “Front” decal on the air cleaner. Those were used on some early to mid sixties Fords on which it was possible to orient the air cleaner more than one way. By '68, the provision of exhaust heat risers and crankcase vent connections meant that the air cleaner could only fit a certain way, and a decal to indicate the front served no purpose. I’ve never seen one in vintage photos or on an unrestored '68 or newer Cougar.
Original style voltage regulator and windshield washer tank would also be nice upgrades, as funds permit.
And here are some nice detail shots showing the correct routing for hoses and wires: http://www.classiccougarcommunity.com/forum/viewtopic.php?t=1449

Front is correct for '69. Moved to the driver’s side in '70:

Here is a photo of my 1970 Cougar H code engine compartment (converted to a 4V). Not concours but an example for you as it has power brakes, power steering and non AC like your photo above. Any questions/comments let me know.

Ah, that explains it. Is this a case where a late '69 or early '70 model could have the other?

I can’t prove that one way or the other, but from what I’ve seen, it would be a rare exception.

While you are painting things blue… The silver duct you are using for a heat riser - paint that blue as well so that it blends in a little better and doesn’t look like you robbed the laundry for some parts.

I have the same set up on my car, but painted blue :wink:

Oh, a few other things you could do…

Get black plug wires, either reproduction or just parts store wires, but in black.
Same with the battery cables, either reproduction or parts store units in red & black.

You could also get one of those battery toppers that makes it look like you have a vintage / original style Autolite battery.

Here are a couple views of a 70 351W engine compartment I did a number of years ago. It isn’t completely concours but it’s reasonably close with the exception of the one piece shock tower brace.



Thanks for the enthusiastic comments everyone. I have a few follow-up queries that I will deal with one at a time.

That sound like a big job to me and one that would require both a mechanic and a spray painter. Is that right, or am I overcomplicating things?

There seem to be lots of fan shrouds to choose from. Are there any obvious traps I should avoid, or does the usual rule apply (i.e. you get what you pay for, so buy the best you can afford)?

Is this the right washer tank? http://www2.cougarpartscatalog.com/69wwres.html

As for the voltage regulator, WCCC says the quality of their repro is poor and they recommend a ‘solid state’ with a repro cover. See http://www2.cougarpartscatalog.com/c8af-cover.html Has anyone done this and is it a good solution? It looks like a nice cheap way to upgrade.

Shock tower brace. Should I respray what I have or put on something better? Yours look more study than mine, but then it could just be that yours has a better finish on it.

I vaguely remember seeing a video or comment from someone at WCCC that recommended upgrading these in a convertible (maybe because of body flex???).

I see that Jeff’s is a single piece. That looks stronger to me.

Any suggestions are appreciated (including from Jeff).

Ah ha! Thanks!

Bwahahahaha! :laughing:

What colour were they from the factory?

I’ve read tons of complaints about the repro VR. I see WCCC is selling just the covers now. I’ll be buying a few of them. A one piece export brace is a nice upgrade. It’s just not correct.

Not difficult, especially since you don’t have A/C plumbing and bracketry to worry about. The accessory brackets unbolt with basic hand tools, and the painting can be done with spray cans. The most time-consuming part is usually getting everything cleaned up and ready for paint. Use a good primer on the bare metal parts, semi-flat black on the brackets, and dark Ford blue on the waterpump/engine.
Snap a pic or two of each component before you remove it, so you’ll have a visual reminder of how things go back together, and you should be good.
