Today was the day finally I tried to crank her without starting her up but that didn't work out too well, the darn thing fired right up, pretty surprising since the engine has been sitting for about 8 months. Had a ginormous fuel leak so I had to shut it right down and figure out where I screwed up. About 3 hours later I rolled her back out of the garage and she roared right back up. With no major issues this time so I let her run for about 5 mins. I thought the 383 would thump a bit more than it does, but shoot I ain't complaining  The pypes exhaust sounds crazy good from the back, not too loud, definately a good combo with the engine and headers.

Many, many thanks to everyone on here that has helped me out, all the input I've gotten so far has made this project what it is!
