On another topic, Andy.... Did you check the net lift with and without lash with the full sping load?
I'm wondering how much flex is in those rockers.
I haven't done that yet but I will try to remember to next time I'm over at the dyno shop. We're planning to do some more carb and intake manifold testing the end of this week. I'd love to hit 700 hp with this combo but I'm guessing that I need a little bigger cam in order to see that number.
Torque peak right now is at 5700 with peak HP at 6300. Cam is 271/.460 lobe single pattern. We'll try a lash cycle and maybe retard the cam a couple of degrees to see which way to go for more power.
