i recently installed a rebuilt passenger car 235 in my 54 truck. i also used a new motor mount in the front. it looks as though the front of the motor is sitting about 1/4" higher then it should. ie the motor is not sitting exactly horizontal.

has anyone else had this problem? i guess i could grind some rubber off the motor mounts. am i missing something?

The engine is not supposed to be level but if the carb base is pretty level then it's OK. The rubber pads deteriorate in time and it's possible that the spacers weren't correct before. This applies to the timing cover mounts and not the later side mounts. Could you have placed the little metal cup that the rubber fits into upside down? Just wondering.

Tim will be along and offer up his one his illustrations before long and that will explain it all.

it has the timing cover mounts. i dont think i installed the cup wrong. it is sitting like a cup with the rubber mount in it and the other metal peice over the top like a cover.

I did the same thing to my '54, I had to clean out all the sludge from the mounts to make sure it sat flush.

Does your new motor sit a bit more forward, that is what seems to be happening to mine.

Good luck.

If the motor is mounted to the original bellhousing and mounts it cant be foreward. I'd compare the front mount 'plate' to the truck type mount. As mentioned, check the carb for level, that's the best check. These motors changed in the early 50s with regard to how they sit in the vehicle as the bodies styles changed.

it has the old bell housing and the new motor.

i suppose it is possible that the timing cover is what is causing the additional height in the front. it looked to be the same shape as the old one.

i'll check the carb for level.

the motor mount is all cleaned up with no junk.

Timing covers are all in the same place on the motor, the 'mount plate' that's behind the timing cover and gears could be the problem. However these mount plates can be drilled for different mounts if needed to fit your truck and can be swapped to another 235 but quite a job, so i'd try to make what you have work.

Nice straight truck btw

i ment to say mount plate, which is behind the timing cover. i did infact drill the plate on my motor so it would mount in my truck.

the carb sits level. i see that manifold is designed to level the carb. so the motor is designed to sit with the front higher. seems odd to me.
