If you had a piston/rod w/a floating wrist pin,
the other w/a pressed pin in the rod in your hands.
You would see & feel the difference that the full floating pin the piston moves so smoothly & flops all around so easily, thus less sticking possibly?
Have you had the two types in your hands @ one time?
The pressed pin will not rotate as easily usually.
In other words if a piston moves more freely on a rod,,there if less friction,, correct?
If it does not move so easily it has more friction thus creating more HP to make the piston move to piston back & forth from the crankshaft turning.
The Mopars I was referring to were the 60's & 70's era V-8's
Maybe this makes sense?
