How do you set the timing on a 1970 Chevy 350?

Use a timing light and turning the distributor. Timing marks (numbers) are in the crankshaft pulley area and the line is on the balancer (next to pulley). Make sure you disconnect the vacumm line to the advance on the distributor while timing and plug the hose while timing. 4BTDC auto trany, TDC standard trany. If the motor is old & worn you can leave the distributor slightly loose & go for a drive and time it manually (with advance hooked up & up to operation temp) to where it won't ping on acceleration and has decent performance.
