6 cyl or V8 and 55 TF?
There is only one precedent that I can think of. . .
The 53/54 Corvettes were all 6 cyl 235ci with 6vdc electrics. For 55, the
265ci V8 was introduced and it used 12vdc electrics; however the 6 cyl
version continued thru 55. . .with the old design 6vdc electrics. I would
suspect that in the vette case that it was a matter of using up parts already
on hand for a design that was phasing out as 55 was the last year for the 6
Maybe GMC was also just using up existing stock? They also didn't seem to be
too bound by model years either from what I've heard from you and others on
58/56 Chevy Suburban
66 Corvair Monza Turbo
86 Chevy Silverado
86 Corvette Indy convertible

using 6 volts? I just pulled in a totally rotted out GMC 300 TF that had an
old 6V battery in the tray. A tail light bulb was 1154, the 6 volt equivalent
of 1157. The inspection sticker says 1969, and son of original owner says
his dad got out of farming then, so parked a good running truck. I'm
baffled. Can't be a retrofit.
