Help me undestand cam timming
BTR specs are, 225/238 .612"/.585" 113+3
Where does the +3 come into play?
The cam card from Comp Cams Says 110 ICL, installing dot to dot I get a ICL of 113, is this the +3?
What I ask is an information request for your intended use ?
What is your intake valve weight ?
The C/L drop to 113 WILL increase engine torque at a HP LOSS OF A 116 C/L.
THEN the +3 Advance ?
You have the Hendrick head with BIG intake ports, good for Cup engines that REV to 9500.

When you say "+3 is deg of advance", what is advanced?
So, is it a 113 ICL advanced to 110 ICL?
BTR is referring to a known grind that is advanced (or retarded) for a given application or maybe as the grind has evolved?
