Hey guys, I'm new to this site.., I didn't know much about the Beaumonts or their Canadian history, but I've been learning a lot. 

So I recently came into a '68 Beaumont Custom, by fluke, and now I'm trying to determin what engine is in the car, and whether or not it is original;

The VIN number is: 736378110xxxx

The driver's rear of motor has a casting number of: 3970010

and the stamped in code in front of the passenger side head reads: K0309 800

 Casting Date Example: E038 - (E = Month, 03 = Day, 8 = Last digit of model year (1978)).

Month: A = Jan, B = Feb, C = Mar, D = Apr, E = May, F = Jun, G = July, H = Aug, I = Sep, J = Oct, K = Nov, L = Dec

I've also read where the engine casting number can be a 327 for 1968?


1968 3970010 327 - - 2 A

from nastyz28

I got a 350 four bolt main block that has K0579 800 on it.  I think Ray is right about the 800 being a service replacement code as it does not show up as a regular suffix code. I have been looking for info on my block and having no luck. Nothing makes sense on the code except  the K.

ok just as I figured it was a 350 and not original to the vehicle..,

but I was hoping it was a 327! anybody in BC got one for sale? :)

I'm in the west Kootenays.., let me know when and if your engine becomes available.

so am I correct in decoding this?

K0309 800: K = McKinnon, 03 = Novemember, 09 = 1969, 800 = Service Replacement

Google tells me the 800 code is for an early GM crate motor like a Targetmaster, which was later renamed "GM Goodwrench" or "Goodwrench 350"



thanks for all the replies!

 That could be the date code that would make my 0579 as May of 79 block. Will have to look at the block casting dates and see if its close to this date. You might be on to something there.

 This is from the Americain Parts Book, I would say yours is a 1979 Targetmaster built in Canada
