Ordered a pull out from Ted's ,should be delivered on Monday.It is supposed to be Navistar 506 motor with less than 40.000 miles.Anybody have any experience with these motors? J.R.

Take a look at the date code on the block.

The first 2 digits are the month followed by the second two digits for the day

06 10 J = June 10th 2002

The 506 casting number has remained the standard casting number since AMG took over the 6.5

The letters are in chronological order with K being 03 and then L, M ,N , O, P AND SO FORTH

Anything with an H or later is an AMG block (H was 2001)

The Navistar logo (Diamond) is cast into the valley
These also have the 506 as the last 3 of the casting ##

See what is on the engine and let us know.
