Blown out exhaust manifold (and tach)

So this is the vid of my manifold after its patch blew out and my tachometer at its best (7000 rpm peak)

Long time no Post

Well it's been a long time since I've posted something so i just thought I'd put in a quick update. Two weeks ago the timing went out on the truck so we replaced the ignition coil and points. The ignition coil is a MSD Blaster 2 the truck is running great so far. Next thing on the to do list is exhaust fixing and new mufflers fix up the carb, new steering wheel , paint and interior.
