67 Fairlane 427 exhaust manifold.

How many tabs are you seeing on #5?

I can't quite make it out clearly but looks like I see two. One on top, one to the right side?

Maybe JD can enlarge that clearly? I'm very interested as to what is on there?


The iron manifolds are intended to be installed on the engine before it gets dropped into the engine compartment so getting them on is not the issue. Getting them off without pulling the engine is.

67 427 Fairlanes have holes drilled at the factory for lower bolt access and plugged with plastic hole plugs as I remember.


Are these ports just dumping into a big common internal chamber on 6 & 7?

   Exactly my point when I said harder than heck to do the bottom bolt addition to a CJ manifold.

   Doug no plastic caps on the Fairlane manifold access holes. They would melt for sure.

I believe he is indicating plastic plugs for access the bolts, not plastic plugs in the manifolds.

  Thanks , I meant access holes , I amended my post.

I'm glad that by bringing up Ricks car 2 years Ago has created some energy here.
He was fun to talk to.
He did infact say he had a Police escort for part of the way.

I might expect a fighter plane escort as well. He has friends.

Here are two images, the one from before closer and another close-up too, they don't show much but maybe enough...

     Ford Motor Co. was not concerned with someone else's whim of wishing to separate the exhaust manifolds from the engine within the chassis.

     And although I missed that engineering committee meeting, I believe the holes in the inner fender wells was intended to aid access to the center spark plugs shrouded by the shock towers.       ;)

JD, Thank you. I have pictures of that corner of his engine but not focused on the exhaust manifold.

What I see in your detail is simple. A cast iron manifold made by Ford does not exist in that bolt configuration. If it does, someone educate that me and post a pic of the manifold.

The combination of three mounting tabs was never made by Ford. I think that is a CJ with a top tab added? Look at my pics above. There is no top tab on #5 on that manifold.

There are only two bolts per cylinder on the cj. Having said that though the head on that engine is still in question to me unless there is another added tab underneath that we can't see in the pics?

To my eye, in JD's second pic, it looks like a 428PI exhaust manifold.

Edit, with welding as Randy indicated.

the "GT" manifold is just a smaller version of the CJ manifold. Still has only two horizontal bolt holes and as such will not fit 427 heads with only top and bottom bolt holes...but I think the answer is those aren't 427 heads on that engine. ;)


Even if what was done was to weld on top bolt bosses on to the manifolds to mate with the all the top holes on 427 heads, what do you do for the bottom holes? Nothing? Just mount the manifolds by the top bolts?

Yes. I do see the weld bead on #5.

Timing can be everything. I was still getting thrown around as red meat draft bait so I could only briefly scan through data like that before my DI would start yelling about Jeezis H. Krist, aren't those boots laced up yet? It was a wonderful time..."best job I ever had!" ;)

Thinking was above my pay grade...and above his too.

I do remember SB Chevy's being like $375 complete over the counter so in proportion anything approaching $1,000 was a pipe dream? L88's weren't out yet but were easier to pick up 'cause of all the 'luminum.

427 Fairlane / Comet manifolds do not fit Mustang / Cougar at all. Been there, tried that. Anyone who says it can be done hasn't tried it.

Again, this is just from memory, but I think he said he had iron Exhaust manifolds.

Either he had 428 heads or shoehorned Fairlane manifolds in there.

   Looking at the date on the paper , one "could" assume "left over engines". Notice there is no mention of "quantity " of said engines.
