'80 442 Vortec swap won't run...

The 442 is finally resemblng a car again... Cool...
I'm impressed how much brighter tail lights, markers, and parking/signals are with LED replacement bulbs... Twice as bright, as they were, before... Easily...

In the process of working out the bugs, discovered the reason for the hissing while running... Turns out I didn't get donut in passenger exhaust lined up right, causing a loud hiss, which I thought was vacuum from intake, until I stood next to it, while running... So glad I don't have to pull intake again....
Also trying out the 14x3 moroso/edelbrock air cleaner....
