While I don't know a lot about HEMI engines I wouldn't use that one piece valley tray unless you REALLY need to Biggest mistake I made when I built my 493 I like your progress so far it should make some nice numbers. I hope it stays cool with your pulley selection because I had almost the same setup for pulleys and mine would run hot after a while of cruising.
