what did you say your cmpression was?

Hey Wyrmrider, Comp is 9.6-1 from memory but id like to get it up over 10 if i could.

Have you measured the lobes? I couldn't find a master lobe list from Crower to see how big the they really are. The adv durations on the crowers are a little long for the total lift so I figure they aren't very agressive. I have a 282 HDP on the shelf i'll try next but I need to get the new carb sorted and some runs in the current configuaration.

What Spring did Mike Jones spec for that cam he ground for you?
