Dan - just stop mate, you have added near on 3 pages of unrelated BS to this guys thread.
This is good advice, heaps of guys are building strokers so im sure you could pick up a 360 crank and set of factory rods for cheap and it allows you to enjoy the car while you plan out & build the engine.
But if your set on re-building the 318 get a set of of KB167 pistons (as long as your not planning on nitrous or boost down the track), use the 360 heads and select an appropriate cam for the application and gears/convertor you are going to run.
