Dunno yet waiting on the cam master to come up with something. .030 seems like a bit much lash for a marine deal. Who's cam are you using?

Previous cam was hydraulic .721 .721 280 296 @50 idled at 500rpm in and out of gear with Holley Dominator Carb. Don't think you can get that kind of idle with EFI and long duration cams for all the carb haters...

My old cams where 276 284 with .750 after valve lash. these made peek 6700 rpm,

I ran the same cam in my Procharged 598 with BB2Xtra and then Big Dukes, did you run the above mentioned springs with it ?

GPM haven't used these springs yet.
What big dukes did you run? And did you ever dyno it? Looking for rpm range.

Did you know that Bullet does not have any lobes in their master list with more than .020 lash? What's the deal with you cam? Something doesn't sound right...

GPM

The lash that they list is at the cam not the valve

Gotcha

Dynoed with both heads, BB2 xtra made 1372 @6200. I never got a good pull with the CNC 1801 Big Duke only know I gained another 6 or so MPH.
And I was wrong about the cam, it was a Comp Cam 276/284 @.050 .782 lift.solid roller. Crower 68806 springs with the 2xtra's, 68848 and then Pac 1348 with the Big Duke.
