In other words paper combos? Bennett learned from the best at Oldsmobile!

My C10 truck is a real 1986 v6 Q-Jet stick truck. The only Paper Parts are the title and a record or two.

There is NOTHING paper about these truck combinations. There are laundry list of them left if someone wants to run out and build a 117" plus wheelbase stocker

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]

I've always wanted to do a 90-91 454SS pickup, but that factor of 310hp on a 2 barrel 7.5:1 454 that was OE rated 255hp really takes the wind out of the sails lol

since the hydramatic debacle it was determined since the sedan deliveries were buiult on station wagon platform it was a car no hydramatics (marv ripes throws a party)

the shaw & wong story was determined opposite since the elco had a 117' WB frame that was only used in this platform from 1977-1987 and was by all GM printed info a truck (sales info and EPA compliance) it was a truck (that cost me bending 6 exhaust valves on my 305 with that 430' cam) bummer

i requested from mr Pat a statement saying such >> i have such a official email states ALL elcos are trucks i even replied and re ask so even a 60 would be a truck with curiosity killing me as to how much a 430 cam might help a 60 283 instead of 399 ... hmmmm and reply was stated > ALL ELCAMINOS ARE TRUCKS.

im not gonna be the guy who tells the SS dudes ill let mr Pat hes great at making friends that way (wait till the AAMA stuff hits)

p.s. i have had the HP reduced on the 78 305/145-180 reduced by 3 last 2 years to 174 and it is still listed in the malibu section but i ve been told the cars cant use it ????

i agree the class guide needs to be fixed showing this as fact

captain

gonna run the elco at vegas and it could be purchased if ya wanna get in on this

RJ, I had a 67 Ranchero 390, 4 speed and wanted to run that in Stock but it wasn't in the guide.
