Just installed a newly built 1987 5.0 in my '66GT. The motor is carburated, not EFI. Running a Crane flat tappet Cam H-260-2 with Windsor Jr. heads. What is a good distributor for this application? Do I need vacuum advance or mechanical only? Are these distributors with an "inclusive" spark box the way to go? This car is for the street, not drag racing. Thanks for your help. GT1966
