how many miles on your truck's factory engine?

[XRT38]

I bought my 1990 LB Comanche new when I in my early 30's.  I had the motor rebuilt about 15 years ago when it wouldn't quite pass emissions with 360K on it. I'm guessing I now have about 500K on the whole. They had to bore it out 60 thousands at the time because the cylinders were oval. Hopefully will last me till I pass on to the great junkyard in the sky. I just changed the oil & filter this evening on it. I always try to change it about every 2,500 to 3,000 miles. Nothing special, just 10/40 or thereabouts with about a quart of Royal Purple Synthetic added to help keep it clean.
