Running a locked msd pro billet on my 12.5-1 493 . I have a digital 6 w start retard, but still get starter kickback and hard starting from time to time. Very annoying to say the least, but once started it runs awesome. Contemplating swapping distributor for a non locked version, or perhaps wire a start switch so I can get engine cranking first and then hit ignition. Built as a race car that wants to do some street cruising as well. Any thoughts?
re- check the timing delay and fix that or [ unlock it.] ... with 12-1 comp ratio it will need a lot of starter to turn that. . i have used them both ways. a second switch will let you spin it over but, i have seen them hang up as soon as you flip the power on too... i would put in a curve...
