I have my '56 210 HT with 2pc frame mostly torn down in anticipation of a new floor pan I'm installing. Since I'm waiting on some supplies to be delivered to make more progress on the floor, I'm revisiting my McGaughy's side motor mounts which I've unbolted and am going to weld in. Part of the reason I did this is because my engine didn't sit level from side to side. I've got the mounts clamped into position and I've manipulated them some to have the two engine mount bolts to run parallel front to back, and they are just a smidge over 16.5" inches from center to center. I'm wondering if someone who has side motor mounts in their tri-five, with no motor currently, can offer me a measurement of how high above some common point on your frame, those two mount tube centers should be. As I manipulate the mounts into a better, level position I want to make sure I haven't raised or lowered them enough to cause other clearance type issues.
Thank you in advance,
Gotta56forme/Scott

A couple of comments.
There is no substitute for using an engine block to mock up the required fit rather than working to dimensions.
Also the McGaughy mounts usually fit rather poorly. A better choice is the Earle Williams mounts.

The 16.5 (actual 16.488 by print) inch dimension is correct for an SBC. Now, remember this is based upon an SBC with the short tabs (1-3/4" Hole Center to Block) Energy Suspension #3.1114 which, for all practical purposes replicates the early GM mounts. You didn't mention what motor mounts you were using.

Hmmm... I have to admit, I wasn't aware there were significant differences in SBC motor mounts. There are mounts already on my motor, but I can't say anything intelligent about them. Anything specific I should I know about sbc motor mount designs/specs?

A picture, is worth a thousand words. Are they an original OEM GM brand or an aftermarket unit? Something like an Energy Suspension brand.

My apologies, lost track of this over the holidays. I had forgotten I had removed the mounts from the block and it took me a bit to find them in a box. Here are two different angles of the mount I'm using. I can't be certain as it was quite some time ago, but I may have specified something like a '70-72 chevelle v8 side mount when I ordered/bought them.
just realized I may not be able to share a pic. I don't have a photo hosting website. Does CT still not allow cut & paste of photos into postings?

Not certain on the C&P. You can email me - nick_prime@sbcglobal.net
According to Energy suspension, that mount is the tall and narrow one.
Center of hole to backside of support (block) is 2-3/16" which, if you are using them will spread the aforementioned distance further out.

Pic received. Stock replacement style for the year Chevy. With it sitting on the board in the picture, measure from the through hole bolt hole center to the board. That will tell me what needs to be known relative to your issue. I will add, what Rick_L mentioned regarding the units from McGaughy's are in many cases the real issue. I'm assuming your units are for the "2 Pc" frame. Are they 3/4 forward units or a stock location as it were?

Yes, 2pc frame, and stock position. I can get the measurement you requested later today.
Thanks!

sorry for the delayed response. Due to how the metal is embossed on the back side, I'd say the bolt centerline is 1&7/8" to 2" from the backside.
