Changed up the intake a little bit, threw a free throttle body spacer (since it was free it couldn't hurt right?) on the vortec, re-routed my amplifiers power wire, played with the hood latch, and drove her 130 miles at 80mph with 3.73 gears and the stock 235/75's... It acted like it didn't mind too bad. May need to get a new throttle body gasket or two to make sure the intake isn't leaking...
Edit: No TB leak, just the whistling sound made me think there was one. Found out my computer thought I had 3.42 gear ratio, no wonder my speedo was off and no cop ever bothered me when I was doing even 15 over the limit... Fixed that, and now I need to fix my windshield washer nozzles...
