Technical Mystery 327 what is it?

Hint ,
Aluminum retainers in/on a stock never been taken apart 327
picture shows them on the intakes only.

 

WITCHCRAFT! Change them out or the Gods of the under world will seek you out!

 

I am pretty sure those were not OEM.

 

Very much original

 

A: is for Aluminum and Aftermarket.
Sorry, that motor has been apart before.

 

You MAY be suprised

 

Why would they put aluminum retainers on the intakes and leave heavy rotators on the exhaust? As to whether it's original not I have no clue it just doesn't make sense

 

And they are SHINY. Look at the gunk everywhere else........ C'mon, man.

 

Did you buy the car new and this is the first time the valve covers have been off? otherwise how could you possibly know?

It may just be a feeling ,but one knows if he's the first, in the assembly phase then the disassembly , when things are NOT disturbed , with EVERYthing in its virgin place.

They wiped off easy, there aluminum.

Jim might be onto something
it might be a 350.?.?.?

 

No numbers on pad (what!!!)

 

Never heard of a hecho in Mexico 327!

 

I've been in GM dealers parts departments since 1970 and never seen a mix either of aluminum and steel in any production motor. And never seen an aluminum retainer used on any production motor either, serious durability issues on those too.

They said it was 1968/69 before your time. (just havin fun).
How bout this oil filter pad (area)---> pic

 

The springs and rotators are shiny as well on the last set of pics. That isn't consistent with ANY old engine I've ever taken apart. The crud does not "just wipe off" and old engine I've ever dealt with either. Let's see the intake, it looks like a standard cast iron piece with a choke stove? So you only "think" you're the first to have it apart? Do you know the history and it's a guessing game for us, or are you looking for help I.D.ing what you think is a factory valve train? Looks pretty rusty on the outside. Marine application? Double grove water pump pulley, not a deep groove, kinda excludes performance duty?

 

they didn't use that short pad on the deck (where the engine number should be stamped) when they were making 327s, it's a later thing (late 70s? 80s?)

I don't see any clues that would make me think it had never been taken apart, or that it is a production engine.

 

Hard to see them (never been apart clues) unless you , were there i guess, no offence,it just had ALL the signs of NOT played with (EVER) , you know EVERYthing in its place , no modern use of gasket goop OF any kind , and the way it came apart,
NOT a single thing OUT of place , no and i do mean NO messed up nuts and bolts.
That may just be conjecture on my part NO BIG deal.

 

Answer is obvious...stock small block option for 41 Willys.

studebaker?

 

You could speed the process by posting casting numbers. Or bore. Or stroke. Or info on where you got it. Checker? Avanti II? Holden?

 

Rare Australian build 327 for even rarer Holden SS!

down the cyl 3.995
010 rear of block casting number

 

4 bolt 327? huh?

 

Did it have the thin steel shim head gaskets?

 

So is more likely to be just a 350.?.
