As noted in Jim Butler's comments in my post #3 one would have to run a very big solid roller cam to come near to 200 degrees duration at 0.200" valve lift. The top cam in his list being 282 at .050 with 195 at 0.200". Even a Comp Race hydraulic roller cam with a whopping 276 @.050" isn't close with 185 degrees at 0.200".

But that's observing the ' 200 degrees duration at .200 lift ' adage often mentioned. There is more to consider like spring pressure, and maybe the rocker arm ratio as well. But either way as Tom suggested it's a lot of cam for most street cars here.
