Wow, I forgot how heavy a SBC cast iron intake manifold can be. My FIL bought a 4bbl intake for the hotrod Camaro so I went over today and pulled the old one. The car is a cobbled up mess, though. I hate wiring/electrical problems so this be a real test for me.
I did impress him with my broken bolt in the head trick of drilling out the broken part with drill bits little by little until it is eliminated.
My back is gonna be tight tonight after leaning over the engine for several hours.
Rick--you have my respect as I doubt I could be a pro mechanic.
