I've seen A LOT of posts about making HP with a 318-So why is it so ???

I'd LOVE to see a 318 build thread that-

A- uses a "reasonable" cam.
Waay too many discussions end up with either "use a .700 lift/.500 duration cam and an 8,000 converter" or
"just use the stock .399 lift cam because nothing else is worth it"

B- understands that there are 2 (really 3) different stock 318 configurations (besides the poly and the Magnum)
with early LA and late LA rollers being 9.2:1 compression rather than the in between years advertised 8:1 and probably lower,
with at least the LA roller probably actually being 9.2.
