crank still good?

i recently had new motor run without oilpressure and fried the top end. my question is their is some slight scarring in the brass bushing in the crank. its not much and you cant feel it but you can see it. the wrist pin is still tight but it worrys me a little. the crank is a 3mm and it only has five minutes on it. the lower rod bearings and the main bearings are still tight and good. im just a little conserned. ive got a new cylinder and piston comeing but dont want the crank to fail after i put it back together???
