I hesitate to bring this up again but, can anyone tell me what year engine I have in my '41? On the bell housing this is cast in raised letters: G 11639 59 To the right of the number X 5 is stamped, not cast. Earlier conversations on this site provided some reference articles but I can't seem to interpret my numbers from these sites.

If is says "59" on the clutch housing, it could be a '42, as a few were produced in the shortened '42 year. They reappeared in '46 and continued thru '48. The usual clue as to whether it is a '41 engine is whether it has the old style double cap distributor, or the "crab" type cap of the '42. The "pancake" distributor appeared in '46, although a few have been reported in the early '46 models. Ford had a habit of using whatever was handy between model year transitions. To further confusion, a good many cars and trucks had engine "transplants" when the junkyards were full of engines. The pressure to build cars after WWII was so great, that Ford used anything available to meet the pent up demand, so don't be surprised what you find.

Hi Super. The 42 car engine used the same block as the 41 3-1/16 " the 41 and 42 blocks were 81A blocks. 81A-6110 A had sleeves. 81A=6110B had no sleeves , both were 3-1/16" cylinders including sleeve. The truck engines were 3 3/16 no sleeve The crab dist started in 42 . The crab dist and the pancake dist can be switched back and forth simply by replacing the hooks with a bail or vise a versa. 41 and 42 engine blocks have a raised surface on both intake surface and exhaust ports. See page 5.2 of the ford club 41 48 book. The heads are also different.

Super, my engine does have the double cap distributor. I have the '41 book. I will look closer at it.

I agree with 42, but the only way to determine the bore is to pull a head. Some of the sleeved engines were converted to the larger bore by pulling the sleeves and honing the bores. We have found early blocks with one or more sleeves, probably to repair a casting problem at the factory. Find a vehicle with it's original engine is usually a rare event.

Does the engine have the "pencil shelf" behind the timing gear cover? If the 59 is large; to the left and up towards the oil sender is there a raised "bump" about the size of a dime? These are just two more things to check, but from what you have described, my guess would be 46-48.
