what kind of compression am i looking at in my 08 dyna with pistons out of 08 103 police bike .030 hg se 255 cams i think police bikes have a 5 thous shorter stroke than the 96in. is it could i get in the 90s hp close to 100 torque i have thunderheader exhaust if that helps

 

your compresion is going to be about the same as it is now,never heard a the stroke being .005 shorter in a cop bike,wouldnt make any real difference any way,90/100 is very doubtful

 

About 9.6/1.
Much better cams out there for your Dyna application.
That 255 emission 110" cam "hits", then falls flat on it's a$$.

ok thanks

 

police service manuals say they are rated at 9-6-1 won't i have a little more with the "030 hg and cam

 

dyna,
You are not listening. You have posted twice on this subject and several knowledgeable forum members have told you two things:

1. you need compression releases with that combination
2. the cam sucks; better choices out there

Take the advice and come up with a different combination.
