318 build

post up some cam #'s and let's see what's what.

with a 318 i'd err toward the smaller cam, especially if you don't have the compression, gears or stall to back it up.

shorter duration and tighter LSA with an early IVC will keep what little dynamic compression you have.

i see 480 lift which makes me think you're looking at a popular 480/280 cam, which is really what you don't want for a 318 unless you're pressing at a true 10:1 and backing it with a 4spd or a decent amount of stall.
