I am waiting for the dyno sheets showing that a lighter pin will gain torque and the resulting HP.

you doubt my claim of .0001 hp, guess you'll have to build and design a dyno capable of reading it. :lol:

No, I think your claim is reasonable.....if you squint real hard at midnight.

The wicked kool old Hot Rod article posted in the MII/MKIII BBC thread claimed pressed pins were used. page 4 photo caption.

Back in those days losing pin locks was sometimes a big problem, and that cost REAL horsepower.


==========
Vintage info from MOPAR about Side effect of tight pin fits in pistons with full float set ups.

With a press fit set up the results could be dire, as pointed out by others.
