'64 WC 401 - timing question

Quick Question:

My 50 year old 401 has 75,000 miles on the clock. After a new prop. shaft, radiator, carb rebuild, and numerous other repairs and replaced parts - before hitting the road come Spring, how much urgency should I place on replacing the the stock timing cam sprocket with a new steel set to protect against the old plastic coating deteriorating and jumping time? How commmon is this occurance in an engine of my vintage and mileage?

Thanks to all.

Jim, just do it. There is no guarantee how long the original will last. But many of my Buicks gave up the timing set in the mid 90K to 110K range. Like you said, you now have a 50 year old set.

Back "then", 75k miles was getting to be "prime territory" for timing chain replacement . . . much less the added age on it now. Consider it "peace of mind" to go ahead and get it changed NOW . . . much better than "then". Right now, doing that "maintenance" will be much less expensive than getting it done + the tow charge, at a more in-opportune time.

If its been sitting for a while, might also consider a new fuel pump, too. Maybe even a fresh fuel filter and ignition points, too?

Enjoy!

The problem with doing this though, is getting the blasted bolts out so you can take the timing cover off. After 50 years, they are going to be a bear. Be careful tith those little ones and take your time. When putting it back together, use plenty of anti sieze.
