[Land-speed] dumb Question # 4856 - Wrist pins

[Rich Fox]

Sort of like my using .990 BBC wrist pins in the Packard instead of .9804
Packard size. Didn't have to rebush the rods, just honed them. Didn't need
special wrist pins, Just bought off the shelf parts. Saved $100 and why not?

pins

Ford uses a wrist pin diameter of 0.912 inches for the little end of the
rod/piston.  GM has a wrist pin diameter of 0.927 inches. I see a number 
of 
Ford products whether pistons or  rods offered with the option of 
using the
GM wrist pin diameter.  I don't know if the Ford pin diameter 
is offered as
an option for GM stuff though. Don't care, lol...

What's up with that?  Is
the GM pin lighter even though it is larger in 
diameter? Stronger for sure
but is that the reason?

So, the dumb question is:  "why switch from 0.912 to
0.927 inch diameter 
wrist pins?

Keep it technical please...
