360 timing

i would prefer a drop in with minimal/no wiring changes. and the jegs options are way out of my price range for now. i have no problem with the "chevy" type cap. but my goodness on my 74' to say it would be REALLY tight would be an undersatement. and I can't help but think there is a lot more to buy to get the gm hei cap distributor to work on my 360, is the mechanical advance easily adjusted in that unit?

Wrong. All that distributor needs to run is ONE 12V hot wire that's hot when the switch is on and in the start position. That's ALL. It also requires no ballast resistor. Just ONE hot wire. Caint get no simpler than that.
