Pin diameter is .927, comp height 1.115, rod 6.125, stroke 4.0, bore 3.780.These work in chevy LS (LM7/L33/etc) motors but require aftermarket 6.125in rods with .927 (floating) pins AND an aftermarket 4.0" stroker crank. The pins and clips are included in this kit along with rings.These pistons are for someone building a 359 stroker out of a 4.8 or 5.3. If that's not what your doing, don't buy this part #.That being said, i haven't installed these yet. They do appear to be high quality pistons that i look forward to using. they are ICON brand / UEM pistons (same company as silv-o-lite but their performance subsidiary i guess). I deducted 1 star because of the fact that the description is inaccurate/incomplete and it led to me purchasing the wrong part. I probably should have noticed the 4.0" stroke but it says it's compatible with my motor on Amazon and they could have easily said they were designed for a 359 stroker.
