Wikipedia's got it right (this time!)- '58 336 was a small-bore 370, and '59 336 was a small-bore 389- actually closer to 337 c.i., as Widipedia said. The rest of the engine was pretty much identical to the cars, except for lower compression ratios- I think dished pistons, but haven't actually seen the inside of a 336. Strictly 2-bbl carbs, and I'm guessing a milder cam. Wasn't the '56 engine (cars and GMC) actually 322 c.i.?
My '59 GMC had a 336 from the factory, but it was long gone when I bought the truck. It will go back together with a Tri-Power '58 engine at 382 c.i. My front fender "GMC" emblems were too pitted to use, so I decided it really ought to say "Pontiac V8" anyway! Over on the "61 & Older" forum, there's quite a lot of discussion of Pontiacs in GMCs.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
