Works out to be a 1949 248 from a Super. The last digit [ 5 ] designates 50 series, Super.
So the engine number is 5,519,225. 1949 began with 5,220,975. 1950 Super began with 5,628,+++, which was the first 263.

So I am finally getting started on the Buick again it’s not locked up!. I know this is a long time to ask a follow up question lol.
Would you happen to think that all component parts are all 49?, or would they work with the 40? Like distributer, coil, starter etc.? I want to get it running!
Looked at the H.EI. For strait 8 on summit. But if I type 40 special it says it’s not a fit. But if I type 49 special it says it fits?

Hello again, Eric.
So glad the engine is not locked up. I believe all components will interchange. I can see no reason for the fit/no fit thing. The only difference, I think, between 1940 -1949 might be the advance curve. Are you going to go 12V?. If so, I have a suggestion. Where are you in MO?

That’s my first step. 12V conversion first thing. I figured since I need a battery anyway might as well start there.
Iam just outside Perryville Mo.
 
There will be a lot of naysayers on the 12V. I am not one. Did my 1950 10-11 years back and never looked back.
I will be happy to offer advice if you need any . I don't know all there is to know, but do know a little.

Decades ago I dropped a 6 cyl flathead from a '53 Plymouth into my '56 Plymouth Savoy (with a 12 volt system). Left the 6 volt starter in place. That starter spun the engine like a dervish, such that it would settle into a slower idle after it fired. My advice: when you do a 12 volt conversion, leave the (presumably good) 6 volt starter in place.
 
Seems like there was a lot of that craziness going on 35 years ago (we're gettin' up there, guys). That's about when I did the conversion to 12 volts on my still unfinished 40 Special. When I earlier converted my 53 Catalina, I used the 6 volt starter, too - it didn't seem to care about the extra volts. Neither did the blower motor. And just this morning, in order to get a fairly good glove compartment out of my parts 40 Special, I removed the defroster motor/core assembly. Surprised that the blower wheel turned freely, I connected it to a 12 volt battery, and it spun merrily away. Neat little setup, I think.
