And do this I set the timing light to 32-34 degrees and set the balancer degree tab to 0? I apologize for the basic questions but I have read so much I am kinda confusing myself,lol. I have read 10 different ways of reading the timing and curve with different lights and different ways of going about it.

you can do that to a point were to much initial will make the engine buck you put to much load to fire the engine and on big CR engines you can end up with a busted starter and it on the floor so you want to try to put is much as you can in the dist really no need to make this to hard for you set it at 32 drive it see how it feels then try it at 34 if it feels the same you can set it back if it start to rattle pull it back . all the vacuum lets you do is pull more timing at no load so the engine runs cooler and you may get better mpg? so under a load the vacuum drops out so will the timming you do not metal the pistons in the oil pan.i use dammper that are degee or tape .so you know were you are and the pointer is @ O so it you rev it to 2500 rpm and its 32 thats what you have you can watch the curve as to when and what rpm it stop at .liter spring make the curve come in faster this is best tune in on the road .what ever you do with the spring s and timming you must make sure the engine stop pulling advance curve or you can blow head gaskets and metal stuff it better to have a bit less then to much so if you run it to lets say 2500 thinking every thing has stop it better to go past that so you know you total timming has stop or she still could be pulling timming and be at 40+at WOT .i would not worry to much about this engine to much if it a driver set it were it run the best .the damper ring can be off you could have the timming right on but not were it needs to be. i do not trust timming lites with curve worked in to them with a button or knob
