another 747 bin

[Ward]

The ACSU was superceeded twice AKAJ then AMUR.
There is a posability that the two 350 may not be the same engine. 

5.7 L05's in Heavy Dutys have a different compression ratio, cam etc. 

Heavy Duty is ant light truck over 8500 GVW. 

Read the fine print in the shop manual.
