karen,

As noted in PvtMail, need the dimension as you lay a straight edge across the frame rails of the chassis measuring vertically to the "bolt hole" on the motor mount plate for the engine. That will give you what was intended to be installed in the chassis.

The bolt thru the mount is 5.25” above the center of the 4” dia main chassis rails, less the 2” top the top of them you will have 3.25” where the mount will bolt thru the mount. That is for the FE, and 2.375” for a 351W small block.

For a big block they mount holes/slots are 17 5/8” across and off centered in the rails by 1 1/8”. A 351 is 18 5/8” for this dimension and uses a different mount. You will have to alter this for a small block and use motor mount PN 2727-DPEA, which is 3.610” in “new condition”, after age and compression, that will be closer to 3.30” in dimension.

Installed the center of the crank should be 3.12” from the top of your main frame rails at the damper bolt point and approx 2.95” at the centerline intersecting at crossing centerline thru mount location.

Cannot go much farther without input or a eMail address to send a sketch of that geometric layout fo the Contemporary.
