Motor Plate Upgrade

The motor plate is made of 1/4" thick, 6061-T6 aluminum.  Hawkeye Weld sheared the plate and drilled the water pump mounting holes to my specifications.  I then fitted it to the frame rail brackets that Mike, at Hawkeye, made up for me.  The finished width of the plate was wider than anything I recall seeing available commercially.  A friend and acquaintance of mine (and moonlighting machinist), Bart, milled the four holes in the plate.
Billet "street rod-series" March pullies dress up the front of the engine.
This picture illustrates the mounting system that I devised for attaching the motor plate to the frame rails.  Three through-bolts attach the bracket to the rail.  The lower one has a 1/2" diameter tube/sleeve that has been inserted into the rail so the frame won't crush when the bolt is tightened down.
This picture shows how the frame bracket fits over the top of the rail pinch weld.  Although not visible in this view, there is a 1/8" plate that is welded to the frame bracket against which the motor plate sets and bolts to.  Mounting bolts at the frame are 3/8".  The socket head cap screw bolts attaching the plate to the mount are 1/2" grade 8.
Here's what the engine sees:  Griffin 31x19 universal aluminum 2-core (1" tubes") radiator.  Mounting brackets were fabricated.  Fan/shroud unit is a Flex-A-Lite dual 12" puller unit, thermostatically controlled.
