First Start 5.3L Powered 1955 Chevy 210 Two Door

First official start up of my 55' Chevy now that the motor is mostly complete. The engine is a 5.3L LM7, with LS1 intake manifold, modified stock truck manifolds, dual 2 1/4 exhaust going into Thush mufflers. I didn't have a MAF sensor hooked up so when I first started it, the idle was jumping around a bit. Last clip is after I added dual tailpipes out under the rear bumper.
