Scary thing is, I understand all of that. LOL
I'm surprised nobody has said "Distributer" or "Coil" yet. Or foot-controlled high-beam switch.
I had a '74 stock Camaro with a 4-bolt main 350. Removed everything vacuum-controlled, Installed Edelbrock headers, manifold, and double-pumper, K&N filter, Mallory Ignition, double-roller timing chain, 0.030-inch overbore with a 3.75 stroke (yep, made it a 383), roller rockers, dyno-tuned, torque bars, BF Goodrich Radial T/A's, and of course, Cragers. LOL
Had the gas-behind-the-license-plate and foot-controlled high-beam switch too.
