Try this for a THOUGHT........:thebirdm: Hahahaha!!! ;)
But seriously - work with me on this and tell me where Im wrong......
As a GENERALISATION (lets assume factory builds to keep this simple) ,
.......a 360 will generate greater rotational force though the crank than a 318, simply because as a general rule, the explosions in the cylinders are greater, and thus make more rotational torque.
I think Im safe in assuming that anyway.
Now - This rotational torque is tranferred through the timing chain to the cam gear and valve train.
I hope thats a correct assumption?
IF........the rotational force through the chain is greater as the engine climbs through the rpm, wouldn't that mean the chain is subject to greater stresses?
Anyhow - Thats the basis of why i was told 360s were harder on chains than 318s "as a general rule of thumb"
Make sense? - or is there a flaw in the logic?
