It appears that you have two different animals as far as timing chains go. Your 420 is probably a V8 which has unique in this area as compared to the six in your 300. I didn't notice what year your 300 is. If it is an M103, don't worry about the chain. If it is a twin cam six, it may be more like the V8, that is, the rails are the culprits to be observed. On the V8, the plastic rails break and cause havoc. I would expect a twin cam six to be similar. Hopefully one of the pro's will comment for you about your specific engines. Some engines like the M103 you don't worry about, and others like the V8's you stay all over.

Good luck,
