94 5.7L engine and bore it .50 and put a .30 stroke

I want to take a 94 5.7L engine and bore it .50 or so over and put a .30 stroke in what all do i need to replace and have done to have the engine run properly and to max efficiently?
What would a estimated price be as well?

First off, you can't bore the 5.7L/350" engine a half inch(.500"), you'll hit water jacket long before you ever get that far.... .060"(sixty thousands of an inch) is usually the maximum you can do.
I take it you meant to say .050"(fifty thousands)??

Secondly, available piston oversizes are normally .020", .030", .040", .060"...... .050" is not a common oversize, and would require you to buy expensive custom made pistons if you are stuck on it having to be the .050" oversize.

Thirdly, .300" added stroke is not a common size either, and would require you to have a custom crankshaft made, which is big $$$$ to have done.
Common stroke size increases are .270"stroker(the 3.75" stroke crank to make a common 383), the .320" stroker(3.800" stroke crank sold by GM and Eagle, makes 383 on an unbored block and 388 at .030" overbore), the .395" stroker(3.875" stroke crank makes a 395" engine).

What are you wanting to actually build here?? 383" stroker is the most common and least costly, and the simplest for a rookie hotrodder to do, the others get a lot more complicated on clearancing of block and rotating assembly.
