1986 305cid ?

how many miles at 60 mph can i drive with a timing chain that jumped and its running under its own power (missing under load). it's a 305 4bbl 700r4 with 212000 miles on the clock was a sound motor before this. yes i should have changed it at 100000 miles. but now its going to cash for clunkers. it think the car is mad at me :lol2: after 24 years 7 months of sole ownership. i am thinking i should just trailer to a block from the dealer ship and drive it in. yes it's a sad day to see her go but cash for clunkers has a $3300.00 discount off the 2010 cadillac srx that is ship and will get in about feb 22.
