The F0327PL you found stamped on a machined surface aft the distributor should read as follows; F - Flint,Michigan, 03 - Month of March, 27 - Day in March, P and L are vehicle and power train options and I don't know what they mean specifically. Hope this little bit will help. I checked what data I have from a recent search such as the one you are making and did not turn up anything on your casting numbers. Ray
