Stupid timing chain factoid
Here you bees. All I have is a 440 double row camshaft sprocket, but they are the same offset from single to double row, so that's the same. Clearly, you can see the offset difference between the two sprockets. Also, you'll notice the 440 sprocket is larger in diameter (that could be because it's for a double roller chain). Lastly, the crank sprockets are NOT the same. They are marked differently indicating TDC for each engine, so anyone who says the timing sets are interchangeable between the slant 6 and big block is unequivocally WRONG.
