After a great 3 days of motivation at the Lake of the Ozarks, I came home and started putting my 948 together so it would be ready when the body comes home from the paint shop. Found out there is no vacuum line to the (Lucas) distributor. Google revealed information at https://www.aptfast.com/APT_Parts/Aseries_Parts/a_Ignition_Components.htm , says "If your compression ratio is above 9.6:1 you may be best to go with the non-vacuum road performance type distributor." My cylinders are running 150 PSI. Anybody have any experience with these? How does it change the spark advance?
