Big Piston Clearance Issue

[DStan]

So I began to clean the second hand 383 that I bought to do a cheap rebuild on and put in my truck. I began cleaning the pistons and numbering them and when I got to the second to last piston I found that it sits WELL above 0 deck. The deck seems level and every other piston is perfectly at 0 deck. Anyone know what could cause this or what to do? I'm thinking maybe just replace that piston and rod.

Very interesting . I'd like to find out too!
Did you get a chance to measure or compare the con. rod/ piston with the other ones?

I thought you would have had a ton of messages by now helping you out with this. thats very interesting by itself!

Well now that I actually got it appart I feel like an idiot. I pulled the pan to find out that the rod cap had about 1/4" of slop where the po had pulled two of the pistons before.

Don't be too hard on yourself, at least you figured it out without damaging any thing.
Good luck.
