AJ's Opinion; what size SBM do I need

Find where I said a 318 is worth PURSUING. Didn't say that. I wouldn't run out and buy a 360 if I already HAD a 318. That 318 would get built. As for bore size, sure, more is good. Not necessarily better for "everything" under the sun, but more is good. I obviously don't care much for bore size since the bore in my engine is 3.445".
