Also, I don't want anyone to think I'm bashing CycleRama. They have called me on may occassions with ideas and whatevers new that they learn. They already have my money. They sincerely are working with me without me calling them.

Pam has called twice in the last three weeks with new information. The ECM download idea was floated to them. They called me. But first they called my HD builders to fill them in on what they had learned. Wes has talked to me a number of times also. I can tell this is getting at him. Good people.

Couldn't agree more.  Wes, Pam and Chuck are great folks....   :2vrolijk_21:

Black Diamond I will throw my .02 cents in the mix.

you say compression tested 185lbs. with 117 jugs and stock heads that should raise comp ratiio, more volume same combustion chamber size, than you put in a longer duration cam which would lower cranking pressure somewhat.

on the acr thread unbalanced had trouble with his acr's and stated normal comp  is 210lbs to 220lbs, it seems to me even with your cams you should be well over 200lbs compression

Jeff noted in an earlier post that the 110 heads had been modified by Cycle Rama....

"CR-Screamin Eagle 110 heads - Port & polish your heads, Multi angle valve job on intakes, radius angle valve job on exhaust. Set valve to valve & seal to retainer clearance, set installed valve spring height, CC chambers, Mill heads. Flow test & Velocity probe ports"
