Topic: Engine Block ID

[Skyway65]

Can anyone ID this block for me? C code, A code, K code  Anything?  TIA 

Date code is "5A28"  Casting # "C5AE-6015-E"

[MattDoscher]

K codes would have 4 bolt mains so it's not a K code.  It could be an A or C code as they all including the K codes used the same 6015-E stampings.

That's a "K" code myth. All 63 thru 67 "K" code engines had two bolt mains.

+1. k-codes did have thicker main caps but not 4-bolt.

[MattDoscher]

Your right, I stand corrected.  K codes had the heavier duty main caps.  If it was a K code block you should find a VIN stamped on the underside.

The engine pictured is correct for a C-Code or A-code 289. A K-code engine block shares same casting (C5AE-6015-E), however was equipped with thicker main caps than the A-code/C-code engines. The main caps you have pictured are not K-code main caps.

Thank you for the responses.  I have a chance to buy this--thinking it might a K code diamond in the rough.  So much for it being my lucky day!  thanks guys.    My recent experience has been with 200 6 engines.

Even that stamping is under discussion as Metuchen "may" have forgotten a few.

Unless I stand corrected, K code blocks also had screw-in oil gallery plugs and likely some sort of HP marking under the flywheel..??

For the "plugs", some did, some didn't. I've been told it's an early (did) vs. late production feature.
The paint marking was supposed to be there, but in a rebuild it often gets washed away in the cleaning process. Your picture is a great discussion starter, and stopper. It would have to be there as an identifier as the VIN was stamped on the engine at the vehicle assembly plant, not the engine assembly plant.

+1. Service replacement Hipo engines for example do not have a VIN stamped .

[Hipo giddyup]

With so many "should haves" it sounds like an unstamped block with the right part number and date could pass as a HIPO? A block that was "missed" in stamping, perhaps never grease/paint marked, or as you've said with these markings washed away during a rebuild, this block in the topic ,though not likely, could be passed off as the real thing.  Its the "common" pieces of the puzzle that we all look for, main caps, balancer, counter weight, rods, vin stamping, etc. thinking its a correct HIPO. 

Always learning something new here.

Can confirm my block was not stamped nor transmission. I bought car from original owner in 1980 with original paperwork and all original dated Hipo parts and service records. Also reconfirmed with original owner a few years ago that drivetrain was not replaced. No screw in plugs either

Where and when did "screw in frost plugs" ever become hi-po lore ? And does anyone have pics ?

Sorry ,scratch that I just reread the post and saw they said oil galley.

Probably due to later Boss cars having it... just a guess.

All it takes is someone putting it in an article, a post online, or any of a number of ways. Same with 4 bolt mains, screw in oil plugs .......

Recall overhearing a comment at a show years ago that went something like "guy doesn't know anything ....didn't even know that Shelbys were sent from San Jose to Shelby with 6 cylinders when they ran short of engines and they put in the K codes at the Shelby plant" 

Who knows where the stuff starts but would like to think that they are just incorrectly informed and not intentional
