External Balance Question?

My balancer is a powerforce balancer and I have a 1999 360 Magnum Engine 408 stroker - cast crank. I took the balancer off today to add some timing tape and noticed the bolt on weight. I checked against the powerforce instructions and the weight matched no 2 below. My engine machinest did the balancing and am thinking he has just made a mistake. Would there be an circumstance whereas he would have bolted in a different weight. He did have my block, crank, rods and the convertor and told me he would balance as well as the machining. I might add this was a couple of years ago so he would no longer remember if I asked him.

-
All 273, 318, 340 and 360 cid V8s including Magnum.

How to Determine Which Counterweight to use:
1. All internally balanced 1967 and later 318 V8 standard and Magnum, all
internally balanced 273 and 340 engines with forged cranks: Do not use any
of the counterweights for these applications.
2. 340 externally balanced 1972-’73 engines with cast crank. Use counter-
weight #91014. (Pt. No. is stamped on weight.)
3. 360 externally balanced 1993-’97 engines with cast crank. Use counter-
weight #91013. (Pt. No. is stamped on weight.)
4. 360 externally balanced 1971-’92 engines with cast crank. Use counter-
weight #91012. (Pt. No. is stamped on weight.)
