ultimate street 318

318; first find a 318-3 truck crank (forged and tougher than a 340 steel crank).
Naaaa, a standard forged crank is capable of alot of power. No need to find a special crank that is not any better than the rest.

Next find a 67 or 68 block with thick cylinders. (.060 -.070 overbore)
While thicker is better, some newer blocks have been found to be as thick, if not thicker. Sonic check it!

Bolt on some race W-2 heads that have been ported (by someone who knows what they are doing)
W2's for a street 318? Whew!

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)

LOL, the more I read this, the more I say 4 inch stroke (or more) in a 4.1 bore (Or more) and lets go budddy!!!!!
