ultimate street 318
318; first find a 318-3 truck crank (forged and tougher than a 340 steel crank). Next find a 67 or 68 block with thick cylinders. (.060 -.070 overbore) Some quality aluminum rods and custom pistons (forged Probe would work) all light weight. Bolt on some race W-2 heads that have been ported (by someone who knows what they are doing) Id opt for the billet main caps with the splayed outer bolts. then a complete roller valve train [jessel?] (solid roller). "Rock the block" up to the freeze plugs. full oiling mods, windage tray etc. Build a custom intake and use a f.a.s.t. fuel injection with twin turbos. (I could go on but ill stop here)
