just got my 5.0 Main support/windage tray today and i have to say i am blown away!!!!!!!!!!!!!!!!!! it is very nice quality finish you name it. 3/4 inch thick plus the windage tray makes it about a inch or more. any one who is thinking about it dont think twice! i picked this over trickflows 1/2 inch steel model. i feel that my engine will now take 600 to the crank with this set-up.
