318Guy,
This is what I would do with the 318, I would get a set of KB 167 pistons, a set of roller rockers 1.5 and pushrods to give you a fully adjustable valvetrain. I would get a XE274 cam or the equiviliant from whom ever you choose. I would also use a M-1 intake with a 750VS carb. I would gasket match the 318 heads and bowl blend them useing the stock size valves and do a good valve job on the heads, use 1 5/8 hedders and good set of free flowing mufflers and you should be able to get 400 or so HP out of it. Just make sure when you get your cam that you get the correct springs and parts for the engine. This should give you a good start as to where to get headed to.
