Hey all, I have a 427 sideoiler block (shortblock) that is identical to the one in this EBAY ad. Mine too is standard bore. In the one main photo of the block, you can see an "H" looking figure painted on the inside of the block. My block has this same "H". It looks like it was acid washed onto there or something.

Anyone know what this "H" represents?
Sorry if this is common knowledge.

And almost $7K, WOW! Does that seem like market value????
Thanks for your time and help.

That block is fairly desirable being the correct one for a 427 Fairlane / Comet or Galaxie. My guess is it needs to be bored at least to 4.250" and maybe .030" so the price is way too high. My guestimate would be it would sell for $2500 - $3000.

The "H" on the back is typical for a 1966 - 68 model year side oiler. Some are also marked "G" and "L" in the same date code range, with all displaying similar characteristics.

By characterisitics, as one obvious example as the dates get to mid summer of 1967 all the side oiler automotive spec 427 blocks get hydraulic lifter provisions.

Hey Royce, Thanks for the reply.
I was referring to the "H" that you can see in the main photo of the ad. that is located underneath where the intake manifold would be. Not the one on the back of the block. Maybe this is the one you were referring to also?

The one I am talking about in definitely put on there with a paint brush and must be acid etched or something.

I too thought this was a ton of money for a standard bore, 427 block.

Thanks again,
Steve

It is a bore size reference having to do with the 4th decoimal place of the dimension. Those painted marks correlated with piston sizes, allowing the assembler to make a quick decision when selecting a piston to properly fit the bore.

Those marks are useless because we don't have a brand new block here. And we don't have a rack of various piston sizes to choose from.

On that eBay one for $6700+

Is it cracked? Does the seller even know?

That is seriously stupid money to be paying unless the buyer had it magged in advance.



The one I bought for $300 and owned for nearly 20 years before getting magged turned out to be cracked in the main webs. There is often a reason these things are sitting around.

The winning bidder has a high percentage of bids from this seller. No way that block is worth more than $2500 IMHO.

It gets tiring seeing so many established scams of ebay sellers with multiple IDs shilling their own FE parts to high prices. They see us as deserving to be ripped off because we are stupid enough to pay these exhorbitant prices. It just saps the hobby.

In this case, the "H" does not refer to the bore grade or bore size. Those markings are 1thru6&ABC or 1thru8&ABCD.

H's can be found in three places on some 427s, depending the era. The C5AE-H, the flywheel face may have a large sand-scratch "H", or the paint marking you refer. I've not noticed the paint marking before and don't know what it means.

etc......

Anyways, that 427 block is nothing remarkable, except for the shill bids. I would avoid that seller, no doubt he has done this before and would do it again.

hi steve you same steve owns ned jerret clone ??jack

yes indeed, jack. this is steve here. the same one that own's the Ned Jarrett car.

Thanks to all that have responded. I think it is probably a marking from the factory. But just to throw another loop in the explanation, I was also told that my block might have been rebuilt or engine repaired (but not bored???) by Rex Hutchison Racing Engines in Sacramento. I thought this "H" might have been his "mark" that he put on engines that he built/worked on.
Just a thought.

Thanks again,
Steve
