I can't find this casting number in ANY of the books or online. I se things that are close in number, but miles apart in application, so I can't even make assumptions from that.
My number is 14015449
I have found 14015443 which is a 4 bolt main MK IV block from 87-90 trucks or motorhomes, and 14015445 which is 78-90 2 or 4 bolt (no other info listed)
Anyone actually have ANYTHING that shows my casting number?

 

Does it really matter?

What's the suffix code stamped onto the pad in front of the passenger side head or on the pad behind the water pump? That will tell you more about a block than a simple casting number. Casting number are used over many years and in many models of vehicles.

Chances are it's just a 454 Mark IV block. What else do you need to know? The heads will be junk anyway but the shortblock is a good start to any buildup. If it's a tall beck block you can build a bigger engine.

How complete is it?

Yeah it matters to me. I want to know as much about the block as I can, there are differences between castings and years and while it would have been fine to find out it's just a standard MK IV block, the fact that it seems to not be on ANY casting number list has me curious.
Not to mention, while planning a build up for this winter, I'd like to know wat I am starting with so I can begin accumulating parts while I'm still driving the car.
Yes it's fast, it's not super loud, but the Hooker headers and Flowmasters give it a nice rumble.
The heads I already know about, truck heads. Which probably means peanut ports. And that's how it acts. I can make earth crushing power up to about 5k rpm and it falls off hard. Burnouts are best accomplished in 2nd gear, as doing a 1st gear burnout puts you at the redline faster than you can shift the gears. But I have Merlin heads on teh way, so no worries there.
I can understand why it doesn't matter to many people, but to me, I like the research. I'd like to know ahead of time if it is a 2 or 4 bolt block without having to pull the pan. Since it is an odd number, I'd like to know if it has any other oddities I should plan around. Siamese bores? Bowtie Block? Boat Anchor? Tall deck? Short deck? Replacement block? Who knows?
The "desktop buildup" of the engine is one third of the fun
Anyone else have info that might be useful besides "who cares?"

Get the suffix code off the block and forget about the casting number! Casting numbers mean very little.

 

Sounds like a Mercruiser Marine block. Not positive, but in most cases marine applications have odd casting numbers.

Suffix is worn off, but the ID code is an oddity too. Usually they start with T and then have the rest of the numbers, including a partial vin. Mine starts with CGJ or CJG (don't remember) which is a known suffix, but not a prefix. Seems like when I looked it up as a suffix code it was a police block or something, been a while since I checked.

 

Um, exactly what are you building these days, Timberwolf? I've been off the boards for a while ... In fact, I've turned into a downright hermit! If only I could figure a way to earn the $1300 I need for my cylinder heads....

Anyone got any used Edelbrock Victor 23 degree heads in 220cc intake volume, 70cc combustion chamber, 7/16 stud configuration? I need a set. I'm tired of seeing these wonderful car parts sitting around. I want to make them run!

Looks like the last casting number may be a 3 afterall. I did find this engine code on the ledge above the timing cover: T0912AKX

I had previously been looking on the ledge behind the alternator on the passenger side of the block to get those other numbers.

any help with the newly discovered code?

14015445...454.......78-90...2 or 4 bolt

That's the closest I could come up with....

Heres a link to other Chevy casting numbers...

T0912AKX

T = Tonawanda engine plant
09 = September
12 = Day of month
AKX = 1986 truck 454 CID. Originally rated at 240 HP. It had a manual transmission behind it. Engine is classified LE-8. The VIN code was W. It was in series 20 and 30 trucks. K20, K30 or C20, C30, etc. 3/4 or 1 ton pickup trucks.

See how much more info you can get from the suffix codes.

I think my block has the same casting number but came from an earlier truck. Mine is a 2 bolt main but having main studs installed then having it line honed makes it stronger than I'm going to need.
