Here is an aftermarket 8000 RPM capable big-block Chevrolet connecting rod used in a 7.4 L (454 ci) engine that uses a MONSTROUS 101.60 mm (4 in.) stroke:
Now, here are our beloved, stumpy little girthy connecting rods used in the, don't exceed 7000 RPM (in the bigger 911 motors it seems the concensus is) engines at a teeny stroke of say, only 74.4mm for a 3.2 (of course the smaller engines have smaller strokes yet down to 66mm!!!!):
I just can't see how we are stressing these things IMO?. Maybe I am missing something, but a stock 911 rod is a beastly little thing!
