Eric's cam challenge
Turk,
Post #286. I didn't miss anything blatantly obvious, this time or any other time.
Apparently, you learned NOTHING from the Crane chart I posted.
Cam 1: 354* adv duration, 264 @ 050
Cam 2: 332* adv duration, 289 @ 050.
So you think cam 1 is going to make more HP....& at a higher rpm....because it has more adv duration, 'because that is what the engine sees', your words [ 'your logic' ].
At some point of valve lift there is going to be meaningful air flow that shapes & defines the power curve for a given cam. Some very smart people, before your time, determined 0.050" lobe lift is about right. It has been in use ever since, & while it might not be perfect in all cases, the duration #s used with 050 lobe lift give a better idea of the power range the cam & peak rpm the cam will have....rather than using seat timing.
