Not close enough unless you're really turning the thing! I've been running my stroker since October 1999. No piston problems, and I can tell you that it pulls great up to about 5K with the cam I have in it! I don't so that often, probably only a dozen times since I've had the engine. I run it up to 3-4K all the time though, and never heard a bit of noise. I've got 40-45K on it at least, could be closer to 50K. No decking of the block or shaving of the head. The quench must be in the 0.080" range since I used stock replacement 4.0L pistons (I later increased the dish depth to reduce compression to run on regular with no ping). I could have got another 15-20 hp out of it by cutting the quench close and running a little more compression, but would have cost me $2500-$3000 in pistons and machine work. Around 260 hp for little more than a standard rebuild was good enough for me. I still have around $4K in a good rebuild, $7K was a bit above my budget! I have to say I'm pleased wit
 h the results.

Oops! yeah, that would be bad!! How close does the wrist pin
travel to the bottom of the bore?
