I know people ask about DCR all the time and I know what it is and understand what it affects. However I got a DCR calculator and crunched all the numbers and I keep coming up with a DCR of around 10:1 with a 228/228 .588/.588 on a 112 lsa cam with stock heads and -4cc forged pistons. Something is severely wrong here I double checked my numbers 10 times at least what am I missing?

 

You have to use advertised durations, not durations at .050"

 

Ah thanks I appreciate it.
