the reduced base circle cam is the same price,so use one if you are worried
I know! I did read somewhere on many forums discussions that the afr 195 flow enough to go with single patern and that a 400+ sbc should be at least with 225. That's why my the other choice was the Howard's 110885-10 but, most part told it opted for the lunati for many street use reasons and Lunati suggested this to 383-400. The 110 lsa will probably not produce vacuum enough for my power brake so, i would install a Vacuum Canister.
Howard's 110885-10 specs:
Basic Operating RPM Range: 2,000-5,800 Intake Duration at 050 inch Lift: 225 Exhaust Duration at 050 inch Lift: 225 Duration at 050 inch Lift: 225 int./225 exh.

I wrote to Howards Cams Online Support and they suggested me the small base circle version of that cam part #119995-S but, i can't find it anywhere.
