Dave the CP pistons have a 1.37 CH and Tim said they were 10.5 to 1 . and yes it is a pump gas deal. It makes things so easy for street driving.
You are real close on the cam. up
The cam is .674 int and exhaust is .657 with the Stage V rockers 1.6 and 1.56 ratios respectively . Lobe lift .421 Duration @ .050 is 264 int. and 270 ex. LSA is 112 * .
This combo works well, and it is a handful on the street. If I were doing more strip than street I might up the compression to 11-1 and a little more cam, but then street and strip is a compromise and I will stay where I am with this for now.
On the strip it revs fast and I am often over revving first gear 1-2 shift. I need more seat time. work
Thanks,
Mark
