Need help deciding what to put in my SBC350

Here is what I am looking at putting in it, what should I change or do differently?
8 Silvolite flattop 4-valve relief pressed pin hypereutectic pistons .040,
Hastings piston rings to match pistons
Clevite 77 rod bearings .020
Clevite 77 main bearing set. .020
Dura-Bond cam bearings
Brass freeze-plug set
Melling High-Volume oil pump with new drive and oil pump pickup
Cloyes double-roller Speed Set timing chain with steel gears and multiple keyway system (to allow cam timing adjustment relative to crankshaft)
SET OF 1010 GUIDE PLATE COMPATIBLE BLACK OXIDED PUSHRODS 5/16"
Full Fel-Pro gasket set
PBM Performance Parts camshaft kit not sure which cam to go with
Also need to know what crank I should put in this.

This is for a temp engine in the Plymouth until I can get a 318 or 360 for it.

LOL Streets I am the kind that keeps the engine with the car. This "mouse" will stay in the ply until I finish the "rat rod" touring car, I call it a rat rod as this will not be a show car, but a daily driver as the body is too rusted and bent to fix up too nice. I do love the 350 but want to keep the ply all mopar or as close to it as possible.

these parts come with the kit I am looking at buying thats why I put in the high volume pump.
and how would I build for " build for 0.035" piston to head clearance" shave the block? or go with a bigger crank? I have only rebuilt engines to std specs. nothing really major with the rebuilds. just using standard specs only replacing the pistons to fit the bore. So I am a little lost with the build for .0035 thing.
Thanks for the help guys.

as for the crank if your not doing anything to drastic with the car just run a plain old cast iron crank, they do a good job on most mid performance build ups and more than 1 high per output motor as well. Its just your rod bolts that you worry about. :)

Sounds good to me, only thing I would add is new rod bolts and resize the rods. Cast iron crank should be fine.

Thanks everyone I understand it now. Tech that explanation is chrystal clear now, The 2 books and the video I have on rebuilding a 350 don't say anything about doing this they talk about bore size and a little about deck height but not much and not really explained to well.
