I have a 1950 gmc 1-ton pick-up with a 1954 235 straight six motor in it. The motor mounts dont sit correctly, must be the orginal motors. Looks like I'm going to have to modify, anyone got any ideas?

Front and/or rear motor mounts?

The 1954 truck rear motor mounts are distinctly different from earlier mounts IF you are using the 1954 clutch housing. Do you know what year clutch housing you have?

1947-53 rear motor mounts

1954-84 rear motor mounts

Is it a Canadian truck? If it is it should be setup for a 216 and the mounts should easily adapt to a 235 using the 1950 bellhouding.

Sounds like someone over complicated this swap.


1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more...
It's true. I really don't do anything but browse the Internet looking for trouble...

The 235 must be a 54 or later Chevy engine-- the GMC used a 228 c.i. IIRC.-- must not have put in new mounts when engine was swapped(as Old Sub suggests).

235s were available from 1941 onwards.

gas dude has identified the engine as a 54 235 going into a 1950 Canadian GMC.

Canadian GMCs (especially the small ones) are different from (small) USA GMCs and Canadian GMCs usually came with 216 or 235 engines (depending on the year).

OldSub, as usual, is most likely correct.
