From what I recall, I think Buick 248 engines from 1941 to 1947 should bolt in. In 1948 they changed the single front engine mount to one on either side of the block. Check on the Buick forum for others such as The Old Guy who can give you a more definitive answer.

Good luck.

Darn near any 248-262 Buick eight can be used IF you pay attention to a few things. You have to use the steel plate behind the timing chain assy off your engine to fit your motor mounts. You have to check the distance between the crank pulley and fan pulley as the water pump went through 2 design changes that changed the fan height so you may have fan/radiator tank clearance issues. Also later engiens with a dynaflow used a different crank than manual trans engines.

This is a swap that has been done often, to the point are you sure you have the original engine??

Pre-41 248 engines have a water pump with a rear cover plate with a dia of about 4" and 41 & newer engines have a water pump with a rear cover plate dia of about 5"
