Can anyone tell me the correct timing for a mild 307.
Its an old one hooked to a powerglide.
Probably from an old GMH Monaro.69-70.
Cheers

All engines are different but a good place to start is unhook the vaccum advance and set it @ 8 degrees. Actual tuning has to be done with time measurements and MPH. That will get you running decent with a mild motor though.
