[DeTomaso] engine mounts, engine moved forward or rearward?

[Will Kooiman]

I moved mine down and back - maybe 1/2" each direction.

I didn't bend the ZF frame mounts.  I cut 1/2" off the mount - the aluminum part.  It's a super thick mount.  It doesn't need to be 2.5" thick.

       Note- all of these mods are for later 2-point ZF mouns. I don't think
       the early single-point ZF mount can be so easily modified. If you want
       to shift the whole powertrain backwards just a little, you can redrill
       the lower motor mounts towards the back. Doing this up to about 1-1/4"
       will not require modifying anything else including the exhaust. You
       will have to adjust the shifter down on its support near the left motor
       mount, and on some cars, the upper bay brace bar gets close to the
       external slave cylinder bracket. Our late '72 L mounts were drilled
       with two different patterns so its mounts were not specfic side to side
       like earlier ones.
       For both of these mods, you must bend the ZF rear frame tabs backward
       into shallow S shapes and remove all the rearmost transaxle shims. This
       may reslant the carb so pay attention to your float heights. You'll be
       shocked at how easily those frame tabs bend. Water pump pliers and a
       small hammer are all you need. 3/4" is enough to allow big cap
       distributors to easily clear a stock firewall. To accommodate big-block
       engines, Bob Byars used to slide the powertrain about 4" backwards,
       which caused the ZF to touch the A/C shroud & need a dent. That much
       movement caused lots of other little clearance mods & required new
       motor mounts. There are over a dozen such Panteras- Forest Goodheart
       has one.

         I know this has been asked before, but is the mount location support
       to
         move the motor forward or rearward?
         Thanks,
         Ken
