this is not pro-touring but i am building a F.A.S.T. car for drag racing.FAST means factory appearing stock tire.so every part has to look factory and correct part #s.i am doing a 69 chevelle 300 deluxe post sedan l89. first problem was when we dynoed the engine we lock the dist. down and used a pertronix ign. in the dist.we ran into where the timing was moving 20 degrees even with the dist. locked.so we put a crank trigger on it to dyno the engine.everything went well.now i need to come up with something to put in a stock gm dist. where i can have a total advance without any timing retard or advance.for ignition box i have a msd programmable 7 [7531] box. any advice would be appreciated. thanks greg
