Nothing was attached to them when I got the truck. They're in an upsidedown triangle pattern. The upper 2 are about 9 - 10 inches from the front of the engine and 4 inches above the pan. The lower one is located below these 2 about 1 1/2 inches above the pan.

The holes here were for side engine mounts. I don't know if all blocks got the holes after that time or not. My 1957 Truck motor does not have them. I might hazard a guess that they are only on blocks for cars not trucks. | | | | | Joined: Feb 2004 Posts: 29,851 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,851 | Those holes are for side engine mounts when the block is paired up with a Powerglide transmission in a passenger car. The PG had a rear mount that fit on a crossmember atr the rear of the transmission, and no bellhousing mounts like a 3-speed standard transmission. Hanging the engine/trans assembly by front and rear put too much stress on the bellhousing, so the front mount was moved to a mid-engine position. I'm restoring a 51 2-door hardtop with that mount setup right now.

I think - nothing. 216 mounting holes -Michael | | | | | Joined: Nov 2007 Posts: 98 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2007 Posts: 98 | I felt silly asking, but thanks to everyone for the answers. | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | The '56 Chevy 2-ton I pulled my Yard Dog's engine out of had side mounts. | | | | | Joined: Jun 2005 Posts: 388 Shop Shark | | Shop Shark Joined: Jun 2005 Posts: 388 | I believe that all of the 1952-54 passenger cars had the side engine mounts being discussed. I had a 1953 Chevy 210 with a standard transmission and several 54 261s that all have the mounts. Some were not drilled and tapped. They are great mounts, but they take up a lot of space. 49-54 Shop manual parts manual Hoyt | | |
