Anyone have an opinion on this cam in a 327, 291 heads, 600 Edelbrock, TH350 w/2200 stall, headers, 3.73 gears, 9.5:1 daily driven '67 Camaro?

Isky 256/262 Supercam (http://www.iskycams.com/timingchart.php?product_number=201256&timing_chart_id=90)

It's similar to the XE268 but has a bit more torque down low than the XE.

CFunk.I got the 270 280 Hyd mega from Isky.It's one of the better cams I have used.It has very good vac. no problems with power brakes,it has a nice rumble,and It comes alive from 1500 to 7000.I also have a 600 3.73s with a 700r4 no stall!If you want I can post the spec.for it!Nick

Thanks for some input. I have actually been looking at 2 of them:

The 256/262 and the 262/270. I am curious as to how they idle. Vac. should be much of a problem as I have 12" now at idle.
