4.6L 2V into a 1970 Cougar?
 
Hey all, I just picked up a 1970 cougar that I am going to slowly restore into a daily driver. Since it's going to be a daily, I am going EFI and 5 speed, it's currently a 351c 2v and C6. I know all about how the 5.0L is the easiest swap and how it can make more power cheaper, but I really do like the modular family and more importantly, I know the mod motors.

Now, I already know that the 4V would require massive reworking of the front suspension, but what about the 2V? Took some measurements from my sisters 99GT and it LOOKS like the 2V will fit in between the shock towers with a touch of cushion on either side. Even if it will fit, I have other questions, mainly with the power steering and A/C. I live in Texas and this car is black, so retaining my factory A/C is a must, anyone know if it would work?

Next up is power steering, how would I go about hooking it up?

Every one i seen done took a shock tower notching or removing.The ac any shop should be able to make the lines to the compressor on it.Power steering probably the same way just make the lines.

Thanks for the info. That solves two of the issues, now the only thing is fitting it, well that and finding a front sump oil pan that doesn't make my wallet cry. It dang sure looks like it would fit and just a quick measurement seems like it would fit.

A guy on modularfords put an 03/04 Mach 1 motor in a 68 (I think). He used a front sump pan (from Canton, which you will need) and notched the shock towers quite a bit. The 2V is not much narrower than the 4V. A Mustang 2 type kit might be easier and cheaper in the long run. You can get a Heidts, R&C, or TCI for about $2K with R&P and disc brakes. That's cheaper than adding those to a stock front suspension.

The 2V is 28 and 5/8 inches wide. The 4V is 30 inches. I thought the 67-68 engine bay was more narrow than a 69-70 engine bay?

That actually give me hope. If he managed to stuff a 4V in there and still keep the towers, I might be able to get a 2V in easy.

Remember, those engine bays had the mighty Boss 429 in there.
I know the Factory had them notched out a bit but you can do the same thing.
Make it count, go with a 4v as the 2v performance is a joke IMO.


I own the same car but I got rid of the shock tower for suspension upgrade more than engine room at the time and I was lurking into putting a 5.4 4v from the early Navigator but I ended up using a 392 stroker out of a 351 Windsor block.

craig71springsport 04-16-2012 06:51 PM

I think either way you have a challenge on your hands. I know how enormous the engine bays on early 70's Ford's are, but still, that's the second widest engine Ford ever made supposedly. Not sure how it will be for clearance on the back of the block with the firewall either. That can probably be worked with. Stock shifter location might be a thing of the past with the 5 speed too.

If you do go ahead with it PLEASE PLEASE PLEASE post pics, I love mod motors in old cars!

JC316 04-16-2012 06:59 PM

Right now I am fixing the main issue, the floor pans. In the mean time, here are some pics of it.

You're lucky...
Your trim pieces are in really good shape, judging by the pictures.
The hood grille is almost always cracked in all the cars I've seen.
The tail light bezels are always pitted as well...
There are no repros and good used ones are simply not around, also getting NOS stuff for this car will mean putting a Lien on your house, lol.

How's your rear glass area, rust wise?

ozarks06 04-16-2012 09:12 PM

Don't worry about firewall clearance. The mod motors are quite a bit shorter than the SBF/BBF. I have room for a Taurus fan, blower pulleys, and a couple of inches to spare with the back of the head in front of the heater fan.

Yeah, she isn't too bad. Don't know about the rust under the top yet, I can see some bubbling through, but I don't know how bad it is yet.

andrewmp6 04-17-2012 12:21 AM

The engine bay is the same size 67-70 its the 64-66 that had the tiny one.And for the boss 429 ford sent the cars out to have the shock towers cut way back to fit that monster in it.

Yeah, vinyl tops are always bad news and.. Rust traps they are.
Good luck with that car, it's a good candidate to start with...

Went out today with a tape measure and started checking. Shock tower to shock tower is 28" on the cougar. The 4.6L 2v is indeed 28.5 inches wide, but that is at the two camshaft sprocket humps on the valve cover. Where that motor would sit, the widest point would be past the shock towers. The portion of the valve cover that would be in between the shock towers, is 27" on the 4.6L. I think that the 4.6L 2V will fit right down in that bay without any modification to the towers.

rwcstang 04-19-2012 06:47 PM

It can be done, I was actually debating this myself I wanted to go with a used 32 4.6 or a new cyte 5.0l. look at AJE engineering u just notch the shock towers and use the 99-04 mustang steering, suspension and brakes which eliminates the upper A-arm, so you can run, say a 18x9 wheel if you like..

I dislike the mustang II suspension, so AJE was my first choice and I have a couple of friends who went with AJE fell in love with it.

I like how ford is now selling the motor and parts that you need to do the conversion.

with the build it was going to cost me 12-15k with parts, u can fish out parts and it will probably be cheaper, like a used t56 or an auto that came out of a 4.6 since they are the same bolt pattern.
