blower
i cant help on cam but on crank i cant think of any way to tell whos crank it is without taking the pan off and that still might not help. I use to have a dyers blower and to fill you remove the top bolt on the trangle little cover if it has one and then remove the other bolt on trangle cover that is down alittle and off to the side on the same cover and fill till i runs out that is how they use to do it, as for the spring i had a dyers intake and a bds intake and they both were set at 1 1/2 inches from bottom of spring to top of spring, now i do know that some set spring at a certain hieght to get a certain pressure but not sure anymore what it is, been awhile since i used them but maybe someone will get on and give you better advice on setting them good luck
