Okay Im gonna need a few opinions. Im completely rebuilding a 2001 b4c and just got the "slightly modified" engine back together. I wanted to do a compression test on it before I put it in the car. Heads have been milled a little bit and Im not sure what this motor should make compression wise stock. Mine was bumpin the needle up around 225 psi. This seems high compared to my other engines I have built. Is this normal or am I going to need to run high octane in it? It is a stock bore 5.7 completely rebuilt but stock bottom end with milled/ported/polished 241s and a pretty big custom grind comp cam. Any input would be great!!
