just lockout the dist you have drop. its not hard to do if its a msd or anything other brand really. i ran my blown 475bbc with lock out dizzy setting at 36degrees, and let my boost timing master msd(6btm msd box) pull out timing when under boost. i didn't need a starter retard, with alittle over 9 to 1 compression, and locked timing at 36 it'd still crank up reallllly easy everytime.
