More running the LT1

[artful dodger]

Another short video of my LT1 running.  I put a temporary exhaust extension on the muffler.  Am I missing some cylinder cooling tinwork that should be over the cylinder fins on the camshaft side of the engine?   Or does the engine mounted fuel tank help with directing the cooling air toward the injector pump.  Seems like most of the cooling air comes out on the side facing us in the video and its cold, ie not really cooling the cylinder.  If I put a space piece of metal over that and direct the air toward the injector pump, its nice and warm, so doing its cooling job.   Gave her a good throttle up a couple times.
