Help IDing a 427 block
Hi gang,
A guy about a hundred miles away from my house says he has a standard bore 66 427 block for sale. Asking price is $500.00. He says that it has the cross bolts on the mains. Questions are:
1. How much is this block worth?
2. How can I positively ID this block? I saw a post where another guy had 67-427 labeled on the rear of a 360. I just don't need another 360!
Thanks all,
Steve

Steve, if you will go find a local engine rebuilder who is a member of the "AERA" (Automotive Engine Rebuilder's Association) they will have books listing engines, blocks, cranks etc by casting number. You can go get the casting number off that block and compare it to the research material and find out what it is. I'm sure that there are other methods but that is the method known to me.

427 written on the block is a good sign. Check the bore, if it's 4.23" and it has cross-bolted mains, odds are it's a 427. I can't imagine somebody going through the trouble to put in the cross-bolts on a block that was bored over the edge of safe running.
If it is indeed a 427 block, it's only worth about $200, but I'll give you $250 just to be nice :-)
Seriously, if it's a 427, and does not need any sleeves to clean up, you could probably fetch big dollars on Ebay. The Cobra guys eat these up.

Ditto what Gtex said. Standard bore 428CJ blocks go for $600-900 on Ebay; 427 blocks more like $2500-3000. The Cobra guys are animals for these blocks plus there's a lot of T-Bolt clones being built out there. You've got a find if it checks out.

Many non 427 blocks have that 66-427 written on them. The crossbolted mains are sorta promising though. Pop one of the freeze plugs out. The 427 cylinders aren't round on the outside. They have kinda rounded corners for added strength. If it is a 427 block it would be a steal at $500 if it were rebuildable.

Just thought of something. Aren't the 427s the only FE block with screw-in freeze plugs? Seem to remember reading that somewhere but don't know if it is universally true....

All '66 427's were sideoilers unless it was a boat or industrial motor. Casting numbers are fairly reliable on the 427, for '66 look for:
C5AE-H, C6AE-B, C6AE-C, C6AE-D
Also check the date code under the oil filter adaptor.

Help IDing a 427 block
Thanks for all of the replys! I picked this block up last night as it looked great when I got there. Bores checked out at 4.23, had all of the cross bolts on the mains with the numbered spacers and screw in freeze plugs. Bores look realy good, no ridge at all but may have been reamed but I still believe that this block will go back standard! I assume that this is a side oiler as it has threaded holes outside of each main on the outside left of the block. It also has 2 large threded holes on the left rear of the block which seems to be part of the oil runner. The numbers below the oil filter housing do not look to be the conventinal Ford scheme, such as D0VE etc. There is 12 DIF by its self. It also has an E1 above the characters 2D27, the 2 is rough looking. Rear bellhousing has 66-427. Inside lifter galley has 427 with 26 below it. It has HP stamped on the top. There's a crank and a set of Lemans rods on Ebay, hehe! ;>)
Thanks!
Steve

Well, here is the funny part, I don't have one. I started out looking for a 460 parts truck for a big block conversion on a 73 Explorer that I have. This guy had an old Ford truck with a 514 stroker and 12-1 compression, too much for what I needed. He said that he had a standard 427 block for 500, so I started checking on what it was worth. At first I bought it to resale, but now I am thinking 65-68 Mustang fastback! Funny thing is, I'm mostly a Chevy/Mopar guy that all of this started by an old friend giving me a factory yellow, very straight 1973 Ford truck. I just love hot rods and big engines, hehe! ;>)
Have a great day,
Steve

Everybody buils mustangs, try a 67ish Couger to be different. Some came with an FE engine setup. Or clean it up, lost of pictures, put it on Ebay with lots of info and use that to pay for part (a big part) of your vehicle :-)
I've seen blocks in good shape go for $2k on Ebay.

It's gotta go in a Galaxie!!!!!!!!!
My Galaxie!!!!! Damn you!!!!
Seriously though, I'd probably swap my brand new, 0 mile, rebuilt 428 for that block. That is a sweet deal you got.
