+ inertia?

So I have been doing some research, I found another continental heavy duty rod that is the same dimensions as an O-200 connecting rod but it weighs about 140 grams more than the stock rod, way more stout...Tim

Per the TCDS

The Model O-200-D is similar to the O-200-A except for special crankshaft flange, overall engine weight reduction, oil sump assembly, and higher compression pistons. The O-200-D does not have provisions for a vacuum pump or the diaphragm fuel pump The Model O-200-X is similar to the O-200-D except for engine dataplate identification.

Does the o200D can any certification?

ok, been digging and found the piston pin height for the different piston that could be used to up the compression in an O-200
stock.......1.591-1.596.....7.0-1 compression
GO-300...1.611-1.616......7.3-1 compression
C-85.......1.698-1.708......????
O-200D...1.745-1.750......8.5-1 compression
So if you want to up your compression, the O-200D will provide the highest compression and is a factory item...I just wish I had some pics of each piston to compare....

Ok, so the Performance Aero pistion is 1.870 ....... 9.0-1 compression
