41orbust Posted July 16, 2017 Share Posted July 16, 2017 I recently purchased 1942 Limited Limousine. Yesterday i saw that the block had the casting for the later (48 an on ) Engine mounts on the sides. However the engine number is a correct 1942 number. The only difference is that the digit 9 indicating the series is the last digit as seen on the later model engines. For 42 I believe the digit 9 should be the first digit. Does anyone know if you could order a newer replacement block and have the original engine numbers stamped in the new block? Is there any way to find out if it is a later block with hydraulic lifters? Thank you 1 Link to comment Share on other sites More sharing options...
Pete Phillips Posted July 16, 2017 Share Posted July 16, 2017 Before the early 1950s (it varies a little by state), nearly all of the states used the car's engine number as the number on the car's title. This causes problems when engines are replaced, so it is conceivable that an older engine number could have been stamped on a newer engine, just to keep from having to reissue the title for the car. To find out if it has hydraulic lifters, take off the engine's side panel cover and pull out a lifter. Link to comment Share on other sites More sharing options...
41orbust Posted July 16, 2017 Author Share Posted July 16, 2017 Hi Pete. Thanks for your comments . Sounds reasonable. I have experienced title problems with engines beeing switched, I will pull the the side panel cover. Tor Link to comment Share on other sites More sharing options...
ILIKECARS53 Posted July 16, 2017 Share Posted July 16, 2017 Hi 40orbust, what model is the 42. I have a model 90 8 pass with jump seats but no division window. All 1942 Limited's are rare. Link to comment Share on other sites More sharing options...
Dynaflash8 Posted July 16, 2017 Share Posted July 16, 2017 (edited) I'd love to find a good 1941 or 1942 Limited. If the front motor mounts are on the side, about 1/4 way back the block there is NO DOUBT the engine is 1948 or newer. However, in 1949 Buick offered new full engines and maybe short blocks for Buicks back to 1937. All you had to do to make them work was unbolt the front steel motor mount plate from the old block and bolt it on the new engine. I suspect that they did not come with a motor number and the Buick dealer who installed the engine simply stamped in the number that was on the original block. That is kind of obvious in fact, so leave it alone and tell your own story. Edited July 16, 2017 by Dynaflash8 (see edit history) Link to comment Share on other sites More sharing options...
41orbust Posted July 17, 2017 Author Share Posted July 17, 2017 Thanks for the interesting information. I did not know Buick offered new full engines for pre war cars. Link to comment Share on other sites More sharing options...

DonMicheletti Posted July 17, 2017 Share Posted July 17, 2017 I think there is an easier way to figure out if you have hydraulic lifters. Taking the side cover off is a PITA. Remove the valve cover and take the rocher arm shaft off. Look at the adjusting screw foor that goes into the pushrod. Hydralulic lifter screws will have a hole like the one on the left in this photo. The one on the right is for solid lifters. The hydraulic lifters are fed oil via the hole and down the pushrod.

sean1997 Posted July 18, 2017 Share Posted July 18, 2017 The series digit was moved to the end of the engine serial number for the 1942 model year, so a 9 at the end would be correct. Link to comment Share on other sites More sharing options...

Just back off the rocker adjusting screw all the way and it can be checked. Not sure about yours, but my 1950 248 with manual lifters has the same "foot" as the hydraulic. Later that year, per the shop manual, it change to what Don mentioned. Might check your Manual. Ben Link to comment Share on other sites More sharing options...
