Re: stock 4.3 crankshaft vs marine 4.3 crankshaft

Posting some more pics of Marine versus stock Sy/Ty... marine is much beefier in certain areas. The pointer in these pics is always pointing at the marine crank.







Stock crank


Marine crank

Re: stock 4.3 crankshaft vs marine 4.3 crankshaft

And just so we have a complete set of picks of all the Crank iterations, here are some picks of the "lightweight" SyTy crank...

Distinguishing mark of the lightweight is this hole in the number one journal...


As opposed to these "heavy" cranks (standard left, marine right)...


And more pics of the lightweight with applicable casting numbers...
