'Pop's Engine' another 440 on the dyno.

txstang84 asked how much duration I lost with running solid lifters and lash on the hydraulic cam. His answer was, 3 degrees, the intake duration went from a measured 242 degrees at .050" to 239 degrees @ .053". This was using .005" hot lash with a 1.6:1 rocker.

Yes, solid lifters stabilized the valve train enough for us to wind it to 6100 rpm where I shut it down. The engine combination was losing power so there was no sense to go higher, it had dropped from a peak of 517 HP @ 5400 rpm to 498 @ 6100 rpm.

What Humber Hump?
