Ok i had a piece of small almuinum that got wedged in between the piston and cylinder wall.it made a small impression in the wall.will this effect anything?Motor is a 383 with zero miles on it!

 

In the area of ring travel or below it?

 

Can you give approximate dimensions of the flaw? It can actually take much more than most people think.

Bout an inch long..if you took a pen and drew a line on a piece of paper thats wat it looks like..its in the travel of the pistons yes i mean its not a big piece is missing just like a little scartch!

 

The aluminum made a scratch in your bore??? sure it wasn't a piece of steel?

Can you catch your fingernail on it?

 

If it were me, I'd run some fine grit sandpaper over it to make sure there isn't a high spot, and run it.

 

If it were aluminum, I would bet that it left material behind instead of scratching the bore. Fingernail test is a good idea. If it truely is a scratch, having it rehoned might not be a bad idea to clean it up. It might take one to two passes to do that. You might want to check the piston/rings for damage, too.
