a stock 90/90 will be plenty for your cam..
if you want room to grow (larger cam) then go with a stock 92..
a ported 90 is better than a stock 92... ported 92 is obviously better than a ported 90..
that cam wont need to breath enough for a ported 90 though IMO... max i could see is 3-4 hp.... not worth the 300 bucks to me..

man i thought i was the only one on ls1 tech right now lol
but time for me to pass out lol
ya i read some where even if the heads flow 300+cfm the fast can still barely flow that so 90/90 should be good

has anyone seen results from the 96 setup before they recommend it over a 90 or 92...i would get the 90 because it can be had for cheaper...the opening on the 90 can be taken to 92 easily with plenty of material left...it is just marketing
