MSD is a great product from my experiences but why not go for the Std or non HEI so you gain room with smaller diameter, remote the coil also a benifit from room and heat soak and more brands of wires available plus you gain a rev limiter in the deal with a 6AL to boot. The MSD has a very user freindly adjustable curve feature also.
What is your manifold vac now and what is historic for your cam/engine? We have slid off problem a bit but still having fun and great bench racing secrets being brought up. What the heck if you throw money at all the stuff we are selling your problem has to be fixed. If it is not the wires as I expect problem to be as a betting man still giving odds of 2/1 . Please post the fix so we know what it was.
