I personally feel like my 400 has more than that dyno'd one. Looking up those cam numbers, my cam isn't too far off (maybe it is). I think that 950 carb hurt the power numbers personally. I would guess my 400 is making 370-375hp maybe. I know it's got a heck of alot more tq than 397ft lbs. Even with 3.23 gears, it PULLS.
