fusion Posted May 28, 2020 Share Posted May 28, 2020 I am putting an 5.3/turbo in my 280z. I am fabricating my own motor mounts and welding them to the frame rails instead of the crossmember to gain space for a downpipe. My frame rails are in great shape. Anyone see any issues with it? I know it's been done before, just wanted to double check. Thanks Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted May 28, 2020 Share Posted May 28, 2020 (edited) With the mount arranged horizontally like that, you are putting a bending moment into the side of the block. The lower bolts at the block are in tension, and the upper edge of the mounting plate is trying to push into the block. Typically, the mount is angled normal to the face of the block to assure that the mounts don't apply bending loads.
