I tore my 347 apart after a missed shift and a loud knock at 1500rpm and so far I found 1 CYL with a loose piston...mabey a 1/16 inch or less up or down with a knock when hit the ball of my hand. The rest are quiet. once I get the other head off ill fill you in on that side. Hope I can save the block.....I should be able to right? any suggs? 
thanks
