I'll get a 3000 or 3200 stall converter to best suit my needs.

This is my daily driver for another year so street manners has to be good and of course, must have performance...I will be tuning this personally from the moment it goes in but wanted some information about the camshafts characteristics before I buy it.
-Comp 280XFI(230/236 with .550 lift w/ 1.52 rockers and 113 lsa)

What I need to know is:
1) How is the idle?
2) Will it pull enough vacuum at 750rpms to run the ABS brakes?

This is for my 1990 Chevy C1500 2wd truck by the way.....I already have this combo in it for reference.
Here is the old combo:
-383
-9.5 compression
-218/224 flat tappet
-AFR 180cc heads
-Pro Magnum 1.52 rollers
-Holley StealthRam induction(stock)
-700R4
-3.73s
-Long tube 1 5/8" headers
-Intermediate dual 3" mandrel bend pipe
-Custom Corsa 3" exhaust
I don't think it will even idle at 750 rpm's.
You don't need a 3,000 to 3,200 stall.
I would think 2,500 to 2,800 would work well.
