I am getting ready to buy an aftermarket HEI dist. and for 50 bucks more I can get a higher output dist. ie. bigger spark. Got me thinkin(ouch) When is too much spark an issue. Does too much spark create a hotter running engine? Is the average HEI spark pleanty of spark? is it the More Spark the better? Anyone have the time to talk "Spark Theroy"? This is for a FI454.
