Re: OST-050 - A VERY special build

These are 18mm wrist pins... and a bit lighter too ;) http://ost.ebeans.ch/albums/userpics/10005/wrist_pin_comparison_2_panel_w_arrows.jpg I decided along with the new 10:1 pistons, that the light weight wrist pins will work nicely in this engine.

And in that vain I've notice that the block[s] I've worked never looked like they carried paint originally.... and apparently they DIDN'T! From 2 very reliable sources I...
