The main reason I suggested the HOR can was that its cheap and has a lifetime 
warranty. Thats my recomendation for a good performance and cost effective for a 
solid lifter motor. 
This is a good street cam, for a solid lifter motor. The word on these was that 
they would flatten the lobes. Im yet to measure and wear on the cam. Besides 
that, if they do flatten, you get a new one for free, AKA lifetime warranty. 


> For Hyd. heads?  I really don't want to loose bottom end.  


The best street cam that I have heard of is the neuspeed 260 deg cam. I've been 
told by a few engineers that this can was made for the 10-1 hyd motors. Now, as 
far as the 8.5-1 motors, I dont know, but I would suspect that it would work 
nearly as good. 
Heres the deal with cams. The more durration and lift you put on a motor, (I.E. 
cam) the less low end your gonna get. It all turns out to be top end 
performance. You also loose fuel economy. Its a give and take proposition. You 
cant have both, but you can have a compromise! You dont really loose bottom end, 
it pretty much stays the same. it just doesnt feel like you've gained 
performance when you hit 3,000 and the thing takes off on you. 
So in that regard, it could seem like you loose bottom end. You dont. As far as 
rough idles with mild/wild cams, I know of a 276 deg cam in a 11.4-1 motor that 
actually idles pretty smoothly. (except when its cold) Then again, YMMV.

A good exhaust is essential in buying a performance cam. Whether it be radical 
or something mild like the G-grind cam. I dont think longevity is an issue if 
you have taken the precautions of breaking in a cam properly.
