RE: does a few degrees of duration make a big diff.

By Norm F. - 03/13/2002 10:17:34 PM; IP 152.163.194.188

Every 10 degrees of duration shifts the power range up or down about 500RPM , lift is not as critical depending on the flow characteristics of the heads and the exhaust and intake systems . Depending on what you are trying to gain , at 6000 RPM given you have a good intake and exhaust the heads on an FE will have the biggest impact on performance. Getting the head flow right could mean 30-40 HP . Cams within 10 degrees duration of each other shift the power range around but are probably within 10-15 HP of each other.Hope that helps.

This thread, so far...
