I recently purchased a 38 Buick and cant id what engine this is. the number behind starter is 43559793. any help would be appreciated.
Probably a typo, but small [ 40 series ] engines are /were 248 CI. Number behind the starter? The engine # on the 248 is in front of the distributor. The 320 # is behind the distributor. Not sure what one means "behind the starter".
thanks for help guys. this number is to the left of the distributor. directly under side cover plate bolt, so it would be a 320?
Beginning engine number for 1938 (for all series) was 3396937. First '39 engine was 3572652. That would place yours late in the '38 model year. Assuming all numbers were actually built, engine production would have been 175,715.
Buick engine numbers did not match frame numbers back in that era. Buick built more engines than cars and numbered each separately. Beginning 1938 car frame number (for all series and all plants) was 3219848. First '39 frame was 3405088. That agrees nearly exactly with published car production of 169,689. So indications are ~7000 more engines than cars were produced that year.

jeffro, some pictures of the engine will help. Something does not compute. Do this for me. Drivers side. there is a crankcase ventilation intake. About 4 in x 2 in. Is it at the front of the engine or the back.
The number you gave does indicate a series 40 which is a 248. Prewar serial numbers started with series number, in your case a four. Postwar, I believe, this was changed to the last number. I was under the impression all 320 engine numbers were behind the distributor while 248 numbers were in front. Pictures of that number and the location of the vent intake will help.
Not a 320ci. 320's are about 3" longer than a 248ci
