Engine Mounts for 73 350

Steed93 · June 15th, 2006, 10:44 AM

I just rebuilt the 350 engine in a 1973 Cutlass Supreme. I purchased engine mounts from Autozone and Napa to find that they both do not fit. The holes do not line up at all, not even close. This is the original engine in the car. I happened to throw out the broken original mounts. Where can I find engine mounts for this car? Year One does not carry parts for the 73's. Has anybody else had this problem of sourcing these parts? Thanks.

Do you mean the mounts don't fit on the engine, don't fit on the frame, or both? '73 should't be a specific year for motor mounts, I would be willing to say that any mounts for the small block from almost any seventies Cutlass body style would fit.

The mounts fit on the engine and would bolt up to the frame, but the bolt holes on the frame and the bolt holes on the mounts don't line up. I will try and get a picture tonight. My Dad picked up a pair of 74 mounts so maybe they will fit. Possibly, Olds had a mid-year mount changeover.

Have them double check the part numbers. I know the mounts for the 455 (7.5 Liter) are different from the 350 (5.7 Liter), but I'm not sure exactly how they are different. Also, Olds listed different part numbers for right and left side but the less expensive ones are the same number and may not fit right.

Figured out the problem. I was right, the 1974 mounts fit just right. This car must have been a late model year build as Olds put 1974 engine mounts on it. I got the mounts at Napa BTW for like $20.
