Yes it's one that you spec'ed and made for me.
I remember you telling me a long time ago to go on 112. Right now I was just wondering what would things be like if it was on 108 or 110. Would it make more he or what.


Thanks

Have u ran it yet?

If you going to be running Douglas track if they hadn't done anything to help traction you going to have your hands full making a full pass. I heard that it is under new management but haven't been there to see how the track is now. But if it is the same as it was like I said you will have full making a full out pass.

Are you sure your dome is 12.5 cc's If it is I'm seeing about 14.3:1 compression if your chambers are at 85-86cc's

Never in my life have i let people not in the know decide if my combo is right or not.

Carry it to the track and wear that bitch out.

Thanks

 Your original statement "looked" like you were asking about changing lobe seperation ( on the cam lobes)from 112 down to 108 and that would be a mistake in everyone's eyes . Now it seems you are only asking about the amount of advance to run on a 114*lsa cam. "To me" the amount of advance that is correct for your application is what ever makes the lowest ET without hurting the MPH. 6*s advance is on the extreme side ( most often it's 2-4) BUT if your car combination likes it that is what you need to run. Just watch intake piston to valve clearance as it will be less by around .028-.030. 69F100 is right , that much advance could make so much bottom end power the track can't handle it.
