What I meant by that, is you don't need to slide the clutch at all on an LT-1 cam. No cam burble at 2000 rpm (hence no jerking in a stick car). I can give you the cam part number that is currently in my 327. While I am fine with rough idles, it's not a primary requirement for me.

Here is the 327 I just finished. 10.5:1, pocket ported 461's, Z28 springs. Idle @ 1100 rpm Nothing fancy. Good to 7000.

With it's current cam (which I'll get you the PN) it carries about 400 lbs of torque from 3500 to 5500. It does require me to slide the clutch a bit more and have a bit more initial timing screwed in than I'd like. I am going to get my wide band sniffer on it this week and see if I can tune around it. Otherwise like I had mentioned, I am going back to the stock LT-1 cam. I've built this combination before in a fuel injected 327 and it just plain works!
