>>>*The specs on the 270/430 are .222? @ .050" lobe lift and .430" lift, 110? centers, single pattern. The spec should not affect test results.

Pretty mellow actually, about the only times it didn't perform up to snuff was with a very free flowing header setup, then it tended to be lazy at lower RPM.

It is simply area under the curve and really should not affect emissions, locally has been no problem but some States have a lot more rigorous test procedures. I think around here they sight down their thumbnail and cute girls can pass anything.


I would think if a profile was ground wrong it would be really showing up as a drivability issue, besides, they are done on a computerized machine, the operator would need to figure out some way to override the program manually.

So unless they actually misboxed(possible) then a misgrind doesn't happen...*EB
