Kade, you seem like a nice young man and I'm sorry I gave you a bit of a hard time.
Just to further your education, a very narrow Lobe Separation Angle (LSA), also called Lobe Displacement Angle (LDA) will give you the rough idle you're looking for, although a cam ground in this manner will peak early and have a very short field of power. 104 degrees is absolutely nasty with very little vacuum (won't operate power brakes), 106 is fairly nasty with little vacuum, 108 and 110 are lopey with low vacuum, 112 is fairly smooth (with decent vacuum) and 114-116 would be a factory (grandma goes to the grocery) kind of a cam that would get you 22 inches of mercury easily.
The cam that Pat suggested is 224 degrees @0.050, 0.483" lift and ground on 115.5 degree lobe centers for a smooth idle and outstanding vacuum. I'm sure he has run this cam before and that's why he recommended it because he knew it would do the best job for you.
You say your father ran a blower, yeah, well, a blower will cover up a multitude of sins in the choice of parts. It's a little more difficult when you're running naturally aspirated.
You may have to call those guys to inquire about the cam.
Again young man, my apologies.PLANET EARTH, INSANE ASYLUM FOR THE UNIVERSE.

I bought the 76 in August , but haven't been able to work on it. When I get a chance I'll post some pictures.
