Same Big Block Question, Same Big Block Problem!

[Old Truck Man]

here is a picture of a 454 engine. When I bought this truck the starter wouldn't turn over the starter wouldn't engage just wirred. Thinking that teeth where off the flywheel I got under it and the flywheel was good. All the teeth where broken off the starter drive. Replaced the starter drive and cranked it over . we had to move the distributer back retarded to get it to start and after it started advance it to get it to run. Now this isn't my first rodeo. After about 5 decades you run upon the same problems from time to time.Checked and sure enough the timing chain was very loose. I pulled the pan and front cover this engine was clean everything looked new. it had a cheep import Roller timing chain that was very stretched. I pulled a rod & main cap and looked at the bearings and they looked new. So I replaced the timing set with a $20 GM link belt one that has a nylon timing gear. Now the beast fires right up and idles perfect. and it will smoke the tires.
