adjustable vacuam advance?
does anyone know where I can p/u an adjustable vacuam advance for my factory distributor.I recently rebuilt my 258 thanks in part to you guys.I did the tr upgrade and was fine tuning the motor with the machine shop guy who was familiar with speed timing and he said I need an adjustable vac. adv.. Long story short any ideas where I can get one for an '81 258 distributor. Has anyone else had to do this? I went .030 over with the block and 0 decked it ,milled the head , comp. cam, weber 38mm, and borla header.Thanks in advance , you guys have been great!!! Gary
