Yup... The 87 I mentioned is definitely not a paper combo.In fact , quite common. For some reason, it was never submitted to NHRA.
If someone goes to the extra length and gets it submitted, nothing wrong or phony about that.

As the Rounded-Line series were redesignated the R/V trucks for 1987, several changes were made to the powertrain line. The 292 I6 was dropped from 3⁄4-ton and 1-ton trucks, with the 4.3 L V6 becoming the sole 6-cylinder engine; all engines adopted fuel injection (with the exception of the 6.2 L diesel).[2][31] In addition, a "smart" powertrain control module (PCM) was also introduced, which controlled the fuel injection system, fuel-to-air burn ratio, engine ignition timing, and (if equipped with an automatic transmission) the Turbo Hydra-Matic's turbine torque converter clutch.[47]
Following the transition of 1⁄2-ton pickups to the fourth-generation GMT400 chassis, the R/V series was offered with three engines from 1987 to 1991: a standard 5.7 L V8 with the option of either a 7.4 L V8 or the 6.2 L diesel V8.[48]
