what you ask for fills abook,do your homework. somethings depend on what you are going to put it in? street, strip, 7.50 digger? what experience do you have? what kind of engine build-ups have you done? do you understand Why you adv or retard a cam? if you have to change cam timing much you may have the wrong cam.this maybe over simple but go to max of manuf specs on pistons, better loose than tight. ive seen tune-ups that are 2-3 thous more than that. good luck with the project, advise thats free is worth about that much.

Will you run it with some water or dry ?
I ran many years with trucks tall decks block , fill to 1 inch to the deck with grouth (kind of no expansion cement), dry , 4.310 , JE pistons , fitted at .006 without any problems . but i kept my tune up a little bit on the rich side.
