I have figured out that it is a '56 235.
Is this a truck engine or a car engine?
Would it have solid or hydraulic lifters? | | | | | Joined: Apr 2005 Posts: 345 Shop Shark | | Shop Shark Joined: Apr 2005 Posts: 345 | I have the same block #. Inline says '55-'57 235-261. I'm assuming it is a truck engine. While not original, (I have a 3/4 ton GMC) my truck had been used as a tow truck & needed a lot of low end torque. I'm still trying to get more info out of one of the P.O.'s. | | | | | Joined: May 2005 Posts: 314 Shop Shark | | Shop Shark Joined: May 2005 Posts: 314 | I thought the serial# was the identifier between truck and car...
The block and head casting #'s are for 1956, but I don't know how to decipher the serial#
Thanks | | | | | Joined: Dec 2004 Posts: 452 Member | | Member Joined: Dec 2004 Posts: 452 | The serial number decodes as follows:
0309751=production sequence number T=Tonawanda engine plant 56=model year X=regular production "Thriftmaster" 235 used in the 3100 series trucks.
A truck engine should have solid lifters.
