Springs and lifters.

if your trying to pinch a little here and there your going to have to do ALOT of research at many places (summit, jegs, local auto parts) a good thing to have is a buddy that works for a parts store or hotrod shop that can get you a discount. but rumble is rite you got to buy them or whats the point in using the 318 all together cuz if you use the old your only asking for it to break.
