Gen 3 vs Gen 4 timing chain set differences? Hey guys, I have a gen 3 block and crank, and swapped over a set of gen 4 rods and pistons from an alum block.
When I pulled the gen 4 block apart, I noticed that the timing chain set was much cleaner and looked to be in better shape then my gen3 gears. I am replacing the timing chain itself, but I was wondering if I could use the gen 4 gears with a gen 3 crank?
I'll snap some pictures of the slight differences that I noticed that made me think this might not be a possibility.
Thanks
Ryan

My shop is a mess right now, I need to find both sets so I can snap a picture, but when I was looking at them and comparing the two, it looked like possibly the timing marks in relation to how it was mounted was different between the two?
Physically they looked the same, I was just curious about the timing marks or if anyone has ever tried swapping. I don't need to swap gears, I just thought it would be better to use the ones that were in better condition.

Gen 3 vs Gen 4 timing chain set differences? You can use the Gen4 sprockets on your Gen3 engine (the crank sprocket is also the oil pump drive)...
the Gen4 cam sprocket's 4x timing reluctor marks are of no consequence since you're getting the cam timing signal from the ruluctor at the rear of your Gen3 cam.
