Are you using the word "solid" as a term of "good cam for a 318" ? Or does it mean you want a "solid lifter cam"? If "solid" is a term word, and you want the rough idle but good street driver, then get a whiplash cam for the 318. If you want a solid lifter cam, then you know you'll need adjustable rockers and pushrods to match.
no, i just meant it as in good I'm looking for something just to liven it up a bit I know options are limited for 318s cause 340s are much better but yes thank you for the recommendation!
