I just changed out the ORIGINAL chain and sprocks on my 1991. The stockers all lasted 11,350 miles! The sprocket teeth look like shark fins and the chain bends sideways almost as well as it bends around the sprockets but it still made it over 11k.
The chain size is a 428 and the oddball thing about it is that you need 124 links... The standard 120 link chains are too short for stock gearing. If you change to "street" gearing and run a 45 tooth rear you can get away with the 120 link chain.
