What should my ignition timing be set to?
My 71 impala requires 6 degrees BTDC for stock setup. But I updated to an HEI distributor for 75-81 application. What should I change my timing too? Should I advance it to like 8-9 degrees BTDC?
I noticed that that car doesn't fire right up after about 15-20 mins of being parked. It takes it like 2-3 seconds to crank up. But if I turn it off and crank it right back up, it'll fire right up no problem??? My timing is set for stock setup.
Initial Timing set @ 8º BTDC, vacuum advance hose disconnected
- Plugs set to .045", unless you have an early model HEI; Plugs are .060"
