Here's a couple pics of the piston and sleeve from my 3.3. I leaned it too much a while back and lost its pinch. It would idle nicely when cool but once it warmed up it stalling. Still had good power all around and the temps were in check, but that stalling issue bugged me and it was easy to spin the flywheel when the engine was cool. So when I tore the truck down for its annual clean-up, shot off $23 via Paypal to Ray A Racing to do a repinch and mailed the piston, sleeve and rod last Wednesday. I've heard he has good turn-around time once he receives it so I'm eagerly waiting for the email saying it's on its way back. I'll post photos once I get it back and since it is going to get cold here--no "warmer" weather in the foreseeable future--I won't know until spring what the results are. He's got good reviews from others in the past and I hope to at least get a few gallons more out of this set. If I do, then it is worth paying 1/2 of a new set (which I have sitting in another block right now).
Here the piston is even with the top of the sleeve. Didn't take much effort to get it to this point.
