Hot Cam ?
Those of you running an lt4 hot cam, what kind of vacuum are you seeing at idle and what is the best idle speed you can acheive?
I'm just curious as to how this cam matches up to a stock cam at idle.
I posted this same question on the carburator board but I think I'll get more responses here.

14"Hg at 750rpm here. I can dial the idle lower, but 750 keeps my teeth from rattling.

Man, I just can't seem to remember $hit these days.... 
..... But I seem to vaguely remember mine being somewhere around 13-14 inches Hg at idle which is set at 650rpm right now (I like the rattling teeth 
).
