What pistons can you use for a 302 bored 050 over can you use 040 over pistons and 010 over rings?

NO, the pistons and rings must be correct for the bore size. Example: Your 302 Ford bored .050 has a 4.050 bore so it would need a piston ofapproximately 4.046 (forged piston) for a clearance of .004 your piston being .010 too small would cause .014 clearance and massive blow by, oil fouling of the plugs, piston noise, scored cylinder walls, poor performance, and VERY short engine life. Get the right parts, do it right the first time, it is cheaper in the long run.
Also if .010 over rings are used in a .050 overbored engine your ring gap would be HUGE! You cannot "add up" the two spec. You need +.050 pistons and +.050 rings.
Please note if you are using cast pistons you can run tighter (smaller) clearances than in the above example. The best method is to have the block bored after you have the pistons, so your machinists can measure them and bore/hone to the exact spec. If your block is already bored and you know the EXACT bore measurement, order them from a reputable piston manufacture as most are pretty accurate now days, just make sure you double check the specs when they arrive.

How do you determine how much to over bore engine?
You determine how much to bore an engine by how much wear is on cylinder walls if wear exceeds .003 thousands over factory specs then it must be bore to the next .010 thousands over cylinders are only bored in .010 thousands increments and every measure is using factory specs as reference point
What is the difference between an 010 350 Chevrolet block and a standard one?
The Cylinders Have Been Bored Ten Thousandths Larger Than When It Came From The Factory. My answer: I don't think the question is about oversizes, few 350 engines are bored .010" over. I believe the questioner was wanting to know about the famous 010 blocks which used to be searched out by the racers. The 010 comes from the casting number of the block. As in 3970010, or something similar. These desirable blocks were reputed to have a bit of added tin to the cast iron mix for a harder stronger block. Many came with 4 bolt main bearing caps. 010 and 020 cast on the front of the blocks is rumored to be alloying metals added during manufacture by GM.
Can you bore out a 4 cylinder engine?
Yes. Boring is simply the process of removing material from the cylinder bore, usually measured in hundredths of inches; .010, .020, etc. However, there are downsides. Stock engine blocks often don't have sufficient material and boring may weaken the cylinder walls. Boring will also require new oversized pistons and rings.
What is thicker 005 or 010?
.010 is thicker than .005
Which number is larger .011 or .010?
.010
How much is 010 of one percent?
Since 010 = 10, 010 of 1% = 10 of 1% = 10% or 0.1

can be both ,i have a 350 010 2bolt main
What should the bore size be on my rebuilt 1997 Chevy silverado 350 engine?
It all depends on how the cylinder walls looked and how much it took to clean them up. I've seen some that needed only a hone, but typically most take at least a .030 over bore. Pistons are usually available in standard, .010, .020, .030, .040, and .060. Anything more than a .060 overbore will be hard to keep cool and really should be sonic tested.
