help ID my buick engine

wondering if any one can help me with the engine i just bought. its out of a 1950 sedenat suppose to be a 263 the book i have n when i go to team buick the first number of sn means what series it is but not sure. want to know if its a 263 with out removing head yet SN61947324 please help if can

 

post some pics of the drivers side of the block there are some reinforcment ribs cast into the block i dont think the 248 or 320 has them

 

If memory serves, the '50 Specials had 248 on stick shift models and 263 on automatics......'51 thru '53 all had 263. It is the last digit in the engine serial number that has some significance, but it indicates the series in which it was installed, not the engine displacement. In your number for instance, that last digit is ' 4 ', indicating a 40 Series (i.e. Special), ' 5 ' would indicate 50 Series (Super) and so on.

thanks guys i will post some photos, its cool to hear all the years of experience

 

If the starter can be used to turn it over a P&G displacement checker would tell you in a heartbeat. The tech guy at most drag strips and circle tracks has access to one.

 

My previous post (#3 above) has been bugging me since I wrote it. It is in error, according to the Standard Catalog of American cars. The SCoA says ALL 1950 Buick Series 40 (Specials) were equipped with 248 cid engines. The 1950 Series 50 (Super) vehicles ALL had 263 cid engines. Transmission type did not matter as to the engine displacement but did vary the horsepower rating a small amount. 1951/52 Series 40 & 50 were equipped with 263 cid engines. 1953 Series 40 were 263 cid straight 8's and 1953 Series 50 & 70 were 322 cid V8's.

Sorry for the previous erroneous info.........I hate it when that happens!
