MattyP, I'm about an hour west of you, just south of Rt. 81. I have a customers 318 in the shop right now that I'm building with mildly ported 302s. Just some bowl work and gasket match. I just ordered a custom hydraulic roller cam, and it is along the lines of 209/217 @.050 and .465" lift, on a 112 LSA with a 107 ICL. That is about where you want to be for that combo, unless you are definitely going with a gear change. With 3.55s, you can go up another 4 to 6 degrees @ .050 on the duration.
