Technical 454 BBC Casting Date?

I understand the casting date for a 454 is in the back by the intake manifold but nothing I can find looks like a casting date . I would like to know so I can sell this engine. It's been in my shop for 20+ years and I'm just not getting to it. I just as well use the money for a current project. Any help is appreciated. Thank you in advance.

Sorry, I can't read all of the characters of this one..

 

@squirrel any ideas?

 

That is an ‘86 454/240 horse engine, it may have come from a C-20 or C-30 truck, or the AKS suffix engines were also sold to MercCruiser for marine use.

 

I'm not questioning your knowledge one bit, I really appreciate your help, I would just like to learn where you determined it's a '86?

No problem, I should have mentioned that I used the AKS engine suffix located behind the timing cover.

 

Ok, awesome! Thank you sir

Larry

 

he found the listing for the AKS suffix

The partial VIN would help if you'd clean it up some...but it looks like CG3... C means Chevy Truck, G is the year 1986

you might find a casting date on the side of the block, above the oil pan rail, look for a letter followed by a few numbers, such as B 22 6

 

Thanks @squirrel!

Yup, found one of these at Pic-N-Pull out of a C 30 School District truck. One of best deals we ever got cheap.

 

This is the only thing on the passenger side:

This is the only thing on the driver's side, it's above the oil filter:

may not be a casting date on it, hmmm...

but anyways, it's a 80s Mark IV 454 block, not much special about that. You can also pull the valve covers and see what's inside, the heads should have a casting number and casting date code also. They should be peanut port heads, open chamber with 2.07/1.72 valves, I think.

Some time in the late 80s they started putting 4 bolt mains on these...I had one in Plan II, it went pretty darn quick with some different innards, heads, blower, etc.

 

Tomorrow I'll pull the valve covers and drop the pan, maybe I'll have a 4 bolt..

There'll be a date on the head when you pull the valve cover, that should help too

 

That K24 may be a casting date.
Nov. 4th 84.
Kinda early for a 86 application.
But if you think first in last out, it could have been pulled from bottom of pile for a early 86 usage.

 

but I've never seen a casting date near that type of foundry mark.....
