Default 454 Engine code

I have a 454 in a 72-Corvette. Donīt believe this is the original engine. The motor is stamped above the valve cover with "TK04XAA8".
Can anybody decode this?

TK O or TK D, can't find TK "zero". General rule of thumb T is for truck!!

Maybe this is your engine!!

Thanks for quick answer.
It is really a "0", may be "O", but definitely no "D".
I read in another forum that the stamping on this position over the valve cover says to which car the engine was mated and on which date. It is stamped there and not casted. As far as I found out already is that the "T" at the beginning might mean Tonawanda plant or so. The "K" might mean November (11th letter in the alphabet), 04 may be 4th (November).
The motor also has casted "Pass High Perf" behind the timing gears and also above the oil filter.
Don´t know how to post pictures, sorry.

If that is true I may be lucky as well. I also have a Txx engine block. Mine turned out to be a truck block from 85 , according to the link.

Pictures is easy,
goto photobucket.com
create an acount,
upload pictures,
and copy the IMG-string under the picture in a forum message.

When you say above the valve cover are you meaning in front of the valve cover/head on a flat pad?

For reference, my 72 has the original engine with T1I0I CSR stamped
in front of the VIN. The Corvette 1968-1982 Restoration Guide decodes the stampings as:

first letter = Plant - T-Towanda, V-Flint
four numbers = mmdd of assembly (the letter I was often used to make up for a shortage of ones).

three letters identifying the engine

So, mine translates to T=Towanda 1I=November 0I=01 CSR=454/270 1972 model year

This makes sense since my car was built on or around December 13th, 1971.

Hope that helps.

Default engine suffix

You might want to relook at your numbers again. T = Towanda plant, K = ?, the next nubmers are generally month and day engine is assembled. 04 = April.... the AA8 might really be AAS, which would call out a 1973 chevy truck, 427, 230 HP, manual transmission. Clean off the area real good, if youi haven't already. You can google "chevy engine suffix codes" and you will bring up alot of information on engines and what car they were placed in.....Hope this helps...

Sorry, the stamped number is above the timing cover, not valve cover!
Try to upload the picture, hope it works.

You need to look at the pad in front of the passenger side head. That is where the engine suffix and assembly date and partial VIN are found.
