The cam is 262in 268ex @.050 w/ 675" lift.
If the port already stalls at .550 then adding more valve without adding port volume ahead of it isn't going to do much. I don't think shrouding is an issue. Or it's less of one than many think. I am curious tho... with those flow numbers, why such a small duration and huge lift? I would think more power will be made staying in the .650 range but adding another 15°-20° of duration at .050. I wouldnt have specd a cam any taller than .630 for those heads.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
