Ok so after reading the last few posts about duration, it would seem that I should be looking for a low duration, low lift cam. As Erik said 220. The cam I already have is 242/242 @ .050", So 220 would bring my opening RPM down by about 1000 RPM.

My cam requires 3000+ stall @ 242 duration, would that mean that a cam with a 220 duration would require 2000?

If so, what is stock stall speed for most factory th350 torque converters?

Does duration affect performance more, less, or the same as valve lift?
