Someone put a B20 in my '62 544. I need to know the engine year. Here are the numbers on the engine: 4969 13 29832
Then down below is: 1-419303

Anyone have the book to look this up in? Any Help? Thanks, Fran

I have a table from the German Volvo club that lists an engine type
496913. It is a B20B with 100 DIN horsepower, which corresponds to
about 115 SAE horsepower. Some on the table are marked "Stromberg".
This one is not so I suspect that means it came with SU carbs and seems
to be 1969 although it might be very late 1968. I don't have any
serial number info so I can't be sure on the year.

By the way, of the number you gave, 4969 13 29832, The last 5 digits
are serial numbers and the 496913 is the engine type.

I haven't found an engine production information source.

Some info could held narrow it down to the B20B, B20E, or B20F category.

1) Does it have injector ports? I.e. a bolt hold and (covered somehow with carbs) hole on the head between the valve cover and each intake port? If not either some rare late model marine motor (unlikely) or (likely) a B20B.

2) If it does have injector holes look at the metal surrounding the cylinder head bolts in the middle of the head along where the intake and exhaust manifolds bolt on. If the flat surface the bolt connects to is sort of an island, its a B20E head. If it has a small flat machined surface that connects with the injector mount surface then its a B20F.

3) If it's a B20F there is no way to tell if it's early (6 bolt) or late (8 bolt) without looking at the flywheel.

All the above to the best of my knowledge.

Why do you need to know? The engines are all nearly identical - at least as near as normally matters unless being rebuilt.
