I have been trying to decide on what style of mounts that I wanted to go with. This is what I ended up with.
Very similar to what I did when I built a 29 sedan back in the mid '90s. Worked great. Kinda hard to see in the pic though.
Not being en Engineer, you seem to have a lot of stress on the top of the frame with just a little square box that is not under the motor pad,holding up, what 600 pounds? I would think you might need a gusset going from the 'pad' area down to the inside of the frame. What is that called? Shear forces?
Yes, shear forces. In full dress, (cast exh/intake manifolds, etc.) the listed weight is 765 lbs. A single gusset running from under the mount 'pedestal' down the boxing plate would spread the concentration of weight equally across the beam (rail) Good suggestion. Also, 'cosmetically correct'!
