Matt Harwood Posted September 15, 2015 Share Posted September 15, 2015 That engine number doesn't seem right to me. The first digit being a 7 indicates a Roadmaster 320, which obviously wouldn't fit in this car. Perhaps a replacement engine or an engine from another car? A Super engine would have a 5 as the first digit. Can anyone look up sequence numbers and perhaps narrow down a date of manufacture? How I miss my friend Dave Corbin.

sean1997 Posted September 15, 2015 Share Posted September 15, 2015 (edited) For 1941 and earlier the series digit is on the left and for 1942-1956 the series digit is on the right. Taking that into consideration, the sequence number indicates the engine is from an 1953 Special, making it a 263. So it seams the engine is not original to the car. See my post above.

BenBuick38 Posted September 15, 2015 Author Share Posted September 15, 2015 (edited) Thank you for the information , so it sems that the engine is replaced , maybe its an 263engine ?Bt Edited September 15, 2015 by BenBuick38 (see edit history) Link to comment Share on other sites More sharing options...
sean1997 Posted September 15, 2015 Share Posted September 15, 2015 Not a 320, but a 263. The 320 is about 6 inches longer than the 263, which is the same size as the 248 that would have been in the car originally. Link to comment Share on other sites More sharing options...

Matt Harwood Posted September 15, 2015 Share Posted September 15, 2015 Oops, I'm sorry, Sean, I didn't see that you'd already addressed the engine number in your first post. Thanks for the clarification! Link to comment Share on other sites More sharing options...
BenBuick38 Posted September 15, 2015 Author Share Posted September 15, 2015 Thank you it was very intresting about the engine , so its a 263 of 1953 //Bt Link to comment Share on other sites More sharing options...
1939_Buick Posted September 15, 2015 Share Posted September 15, 2015 The 263 ci will have 4 stud threaded holes on the side of the crankcase that were used for the engine mounts. When a later engine is installed in an earlier car these are not used. The 263ci is a better engine. Link to comment Share on other sites More sharing options...
1967 - 1997 Riviera Posted September 15, 2015 Share Posted September 15, 2015 If the 263 I8 engine was introduced in 1950, and this re-engined 1941 model had an I.D. plate that matches that engine and not the original one, does that mean that the newer engine was dealer installed and that they re-badged it when the retrofit was completed? Seems to me that would make this a semi-legitimate upgrade with a warranty to go with it back then. Also, was the engine painted a grey color to siginify that it was a replacement as opposed to the factory red or blue? Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted September 15, 2015 Share Posted September 15, 2015 1967-1997, Sean identified the ENGINE from the engine number on the block, I believe, not the I.D. [data] plate. The valve cover looks to be black, which all post war I 8's I have seen seem to have been primed with. Too bad the turquoise paint did not last as long. The engine picture shown for sure has a ,49 or later valve cover installed as evidenced by the saddle for the air cleaner. Of course that means nothing. The water pump to block connector, I believe, started in '50. A pic of the mounting pads, preferably driver side, would confirm what Sean has said.

BenBuick38 Posted September 16, 2015 Author Share Posted September 16, 2015 More pictures of the engine ,Why is the 263 better than 240, whats the diffrence, and the 1953 was the last year of the straight 8 //Bt Link to comment Share on other sites More sharing options...

In image 1, the side engine mount is clearly visible. These FIRST came in 1948. Just to the right of the pad can be seen a rib on the block. These are ONLY on a 263, which came out in 1950, in the Super. So therefore , a 263, 1950 or later. Sean has confirmed it as a 1953, and yes, last year of Straight Eight, in the Special only.
