Greetings everyone!

I just purchased an old continental, 1970 model, and had a few questions someone might be able to answer about leaded vs unleaded fuel...

I got this off an old farmer and he was pretty insistent that no work had ever been done to the motor.. I will do a stroke/rebuild or 521 swap but not until next winter. Until then, should I run the normal 93 octane unleaded or run 93 along with some lead subsitute I've seen for sale, or am I going to have to run 100 octane LL all the time? Will I have to pull some timing? The car wont be drove much.

Thanks for any info/suggestions, it's appreciated!

Hi Wewsnu

If the car was mine I would use 95 octane lead free gas straight from the pump and fix any valve recession if it occured especially as you say it isn't going to be used much, maybe knock the timing back a couple degrees if it pinks too bad.
