GM’s Task Force Series pickup was built from mid-1955 through 1959. The design was shared between both Chevrolet and GMC, with upgrades including available V8 engines, 12-volt electrical systems, optional power steering and power brake systems, wrap-around windshields, Wide-Side beds, and even wrap-around rear windows on deluxe models.
According to the seller, this light blue Wide-Side has only 26,338 original miles, with only a full cab and bed paint job some 30 years ago. It was parked in 1976 when the original owner (the seller’s great grandfather) stopped driving. The 336-ci V8 was the largest offered in the truck range at the time, and this one is said to have been still since the mid-1980s—although it apparently ran fine at the time and appears to still be complete.
Cosmetic needs include a mismatched ‘Chevrolet’ script tailgate, body scratches, no rear bumper, and some tears to the seat. The pictures posted suggest long-term dry storage, which is a huge plus, as rust can be an issue with these. 1955-1959 GM trucks are seeing increases in value, and over the past year, 268 have sold on eBay Motors. If you’re looking for a barn-find classic American truck, take a look at this one.

I have never herd of a 336 G M v 8 chevy engine. there was a 265 – 283-348 in59, Could the 336 be a big block 348? thanks
True, Chevrolet did not have a 336-ci engine, the 336-ci was a GMC V8 in the Task Force Series trucks used in 1958 and 1959. Bore & Stroke: 3.875 x 3.5625.
In 59′, GMC used Pontiac engines in the heavy duty trucks. Engine was painted orange and reverse cooling through the heads. The V8 was a 336. I don’t think it was available in the half ton model though. Only 1 ton and up.
This was a Pontiac V8! Was only offered in the GMC truck. Very nice example that I’d like to own.
