Fireball V6 Engine Serial Number - What does it mean???

[fiftyv8]

Guys, I have a Buick V6 engine I have inherited from a friend and need to ID it.
From what I can read off the engine block from the serial number is as follows; 5K113312 the 5 could be a an S just not quite clear.

I have search around a couple of sites but not found a translation for these numbers to tell me exactly what I have.

Is it a 225 and what year is it etc and should the 1st digit in the serial number be a numeral or a letter "5" or an "S" ?.

I would appreciate any help.

Thanks, Russ.

What you are describing doesn't seem to work. Did you look at this:

Yes it will work if somebody knows about V6 engines, I have the engine and the number in front of me.
I was told the K means 1964 but other than that I dont know.

Bob, that looks like an EIN.



I was told the K means 1964

no, the "K" should mean it's from the Kansas City, MO plant. if you were reading us the two letter Engine Code stamping ( http://www.teambuick.com/forums/view...t_engine_63-75 ) THEN the K would indicate year.

the EIN decodes the same way a VIN does, it's just a fraction of the VIN that doesn't include make/model information.


5 K 113312
5 = either 1965 or 1975
K = Kansas City, MO
113312 = sequential production number, this would match the last 6 digits of the VIN from the car that the engine came from

the problem here is that the oddfire 225 was available in 1965 and the oddfire 231 was available in 1975. so we haven't really learned much.

i think HEI distributors came in around 1974, so if you have a points distributor in it there's a good chance it's the 60s era engine.

the definitive way to figure this out ( without disassembling the engine, of course ) would be to find the two digit Engine Code:
http://www.teambuick.com/forums/view...t_engine_where
"The production code number can be found on the crankcase between the front and middle branches of the right exhaust manifold."

there's a chance we could ID this from 225 specific casting numbers as well, we've got some of the block and head numbers for the 198 and 225:

Well thanks for the information, it has answered my question.
I will check the casting number under the exhaust ports.
From the looks and the comments of the previous owner it is the misfire 225 engine.
I guess when it runs that will give it away regarding its misfire status.
