[GMCDAC]

Well I'm jumping back and forth between GMC's but it was warm enough today to have the shop door open and fire up the '72 to find out if rebuilding the Holley was going to do the trick. I was kinda paranoid that I had an intake manifold vacuum leak on the underside but that was not the case! It seems to run great, and I even took it down to a gas station to treat it to a nice tank of non-ethanol premium! That was a little risky too since there is a come-a-long holding the the old mufflers in place. Nothing fell off so all is good.

I re-routed and shortened the vacuum advance hose and electric choke wire since I took the pic earlier today. The third pic shows the stuff I gotta weld together to build a new header-back exhaust system.
