I would like help decoding the vin and engine size on my GMC truck.
Although the grille has a 350 emblem, it has a 6 cyl.
Flatbed dually
Tag reads as follows:
Vin:353 c t 1014
Gross hp:140 @3600
Net hp: 127 @3400
Gross weight:16000
Combination weight:32000


Any help would be appreciated.
I just bought it.

What engine options were available?
Thanks for any help
