Ok folks,

    Fired up the engine with the new intake with the polyurethane resin
casting plenum/throttle body - Fuel injector mount using Paul's manifold
casting.  The good news is that while I don't appeared to have picked up any
performance at static (didn't really expect to as I put on shorter and
bigger tubes which should have raised the rpm for best torque over the old
system), but on the other hand the plastic plenum didn't blow up either
{:>).

    Static on runup was 5400 rpm with air temp at 80F and 100% humidity.
Idle would not come down below 2200 rpm indicating an air leak.  OR the
3/16" dia hole in the throttle plate needs plugging.  I stuck my thumb over
it and the rpm did drop, couldn't tell how much as could not watch the tach
while doing that, but it sounded like a couple hundred rpm.  I'll use some
JB weld to plug the hole and then see.

   Here are a couple of photos.  One of my objectives was to reduce weight
and  I have shaved off 12 lbs off the old intake with the new one weight 11
lbs with manifold casting, tubes, plenum, throttle body, fuel injectors and
fuel rail.  .  Another objective was to clean up the exhaust side of the
block for later putting a turbocharger there.  As the second photo shows,
plenty of room for the turbo now, note how snuggly Paul's casting bolts up..
Note the oil on bottom of flange from cutting and refitting oil pressure
sensor line.
