what is it???

[68fecyclone]

No 352 also had them, and they say early 390, 406, 427 cranks had them till 64 or 65.  I have no personel experience with them, so not absolutely sure on those. Rob

thanks Kevin, Bruce good info
  did you notice in my pic that there are the two protrutions for the side oiler
that are not drilled. So it could be a 427 marine or industrial engine.
  The bottom line is the engine with buying?
IC no marking around the  427 casting

PS: guess I did not get enough info when I was there yesterday

Sandoc, it is almost certainly nothing special.  Nothing so far has made it look like anything other than a block that used the rear bulkhead, a bunch of them out there.

Us old farts have had a ton of them come and go.  For 100 bucks, worst case is you have 100 bucks worth of 352 or 390.

I have raced home too many times with treasures, that 66-427 means nothing on a 2 bolt block

427 industrial are rarer than hens teeth and like "may not believe they exist" rare, and 428 industrials would not have those heads and generally didnt have the 66-427 rear pattern.  This comes from a guy who would buy trailer loads of propane 428s trying to find 427s.  Never did

I thought you said 125 dollars though, that's cheap enough for any gamble, even parting it out might get you back to even if it was a 390

I am almost at the point to just let it go.
 He started at $200, I was getting him down as low as possible.
I've seen just blocks and cranks for $50, and one guy in San Diego has a load
of heads for $15 each. I am sure some of you are in Calif I'm in Los Anegels
area, so I check out CL all the time. Think I'll wait for for a 428 or a real 427
to show up, I am in no big rush for an FE 
 But I do want to thank everyone who had input into this...

There are some parts on that engine you will need.
The front cover and the oil filter housing.
Not to mention the heads and all the bolts.
Those C6 heads are an excellent starting point for an FE build.
Beat him done to scrap price and keep what you need and scarp the rest.
Keep the big picture open. You need all the parts to build an FE.
Not just the block.

[sanddoc]

So here I go again.
  C6AE or C8AE    with (J) 
From my reading there are only 2 heads that use the C6AE casting
a (SOHC) or the 66 FE big block but that ends with a R

the C8AE   (J) is a 68 cougar or mustang low raiser...
 caveat is that I know the exhaust ports are 2 bolts each
So I'm going to drive down and see this engine again, and take a
magnifying glass and also find that block casting...
 these numbers came from 2 different sources, but probably from the same
original source.... 1 is MustangTek, the other is Hot Rod reference...

Dave,
While you're at it, good to check the block's date code; it can be found underneath, if I remember near the oil filter housing. The code is 3 numbers and a letter, i.e. 8C11 would be March 11, 1968. All letters were used except for the letter "I". The date code can be of help in identifying the block and as Barry R says, sometimes by exclusion.

There are at least 4 normal production FE heads ( not SOHC ) that start with C6AE. There are -J, -L, -R, -U. There are also more FE heads in '66 with other castings - C6OE-AE, C6OE-Y, C6TE-G, C6JE, none of which apply to what you are looking at, but I'll list for info purposes. There were probably more FE head castings in 1966 than any other year. And many of those can be machined multiple ways, 8 bolt exhaust, 14 bolt exhaust, Thermactor ( smog ) bosses or ports. There are at least another 8 more castings I've seen mentioned. One thing you will learn is do not rely on some of the published books. MustangTek is pretty good, but not complete. As I mentioned before, be sure and check date codes, not only can they affect what you might be looking at but also the value. And although the C8AE-J heads were used on Mustangs and Cougars, which would normally be 14 bolt exhaust, some of these were early production cars and some were meant for racing, they can still be 8 bolt exhaust. Don't be afraid to take pictures. And I'll agree with Howie, even if it's not exactly what you are looking for the small parts and accessories are worth it if you can get the engine cheap enough.

C1AE-A and C4AE-B cranks are 3.78 stroke and have the half moon cut out on the crank

C4AE-B on the left the other 2 cranks are steel 427 cranks

Sanddoc you are killing me LOL
C8AE-J - might be from a Cougar 427, but most value is for the early CJs.  Before the C8OE-N, the -135 cars (first REAL CJs) used C8AE-J, a very good head to sell off but super rare.

C6AE-J - nothing special at all

I can't tell you not to research, but the old guys here know more than the crappy books and websites out there. 

Just go look at it, if it is really a C8AE-J, buy the pile, if it isn't walk away or buy it, the parts have some value.

There is no mystery here LOL

Got the same heads on the 410 pickup truck engine out in the barn. Wish they had smaller chambers but they are what they are, basic FE heads.
