The cover plate is 3/16" billet aluminum had a local machinst make and bend it up.The shrouding top,front and
oil cooler surround I did myself with 1/8" aluminum.Made cardboard templates to fit then tweaked after aluminum was cut.Before the shrouding thought I had a problem with engine running warm,turned out the 460 just comes to temp quick with no engine fan then stabilizes at 190.The electric fan does not run as much.
