I just picked up a 1969 jeep J2000 in pretty good condition. I have two questions. First is how do I confirm a matching numbers motor? I was told it has the 350 Buick dauntless motor. Secondly did the 69 come with a factory air option? This truck has A/C.

thank you
Rick

I don’t have those answers, but that looks like a really fun project. Congrats.

You need to contact Shannon Halverson. He knows the old Jeeps very well.

350[edit]

A 350 in a 1969 Buick Gran Sport
Buick adopted the popular 350 cu in (5.7 L) size in 1968 for their final family of V8 engines, the 350, which was produced through 1980. Although it shared the displacement of the other GM small blocks, including the Chevrolet 350, Oldsmobile 350, and Pontiac 350 (although the Pontiac was technically a 354), the Buick blocks were of a substantially different proprietary company design. The Buick 350 featured the same 3.8 in (96.5 mm) bore as the 231 cu in (3.8 L) version of the Buick 90° V6 and retained the 3.85 in (97.8 mm) stroke of the previous 340 cu in (5.6 L) V8. The exact displacement is 349.31 cu in (5,724 cc).

The major differences of the 350 in comparison to other GM V8s are Buick's "deep-skirt" engine block construction, the use of cast iron with increased nickel content, an external oil pump, a forward-mounted distributor, under-square cylinder bore sizing, 3 in (76.2 mm) crankshaft main journals, and 6.385 in (162.2 mm) connecting rods. The Buick 350 also shares an integrated aluminum timing cover, which incorporates the oil pump mechanisms, leaving the oil filter exposed to oncoming air for added cooling. The engine garnered a reputation as rugged and durable,[17] and some of its design characteristics are found in other Buick-designed GM engines, such as the 231 cu in (3.8 L) V6 and its 3800 descendants. Of all the GM "350s", the Buick has the longest piston stroke. This design characteristic made the engine significantly wider than the others — essentially the same as the Buick big-blocks, which have the shortest stroke of the GM big-blocks.

The 350 was used by Kaiser-Jeep and AMC Jeep in the Jeep Gladiator and Wagoneer models from 1968–71;[18] in these applications, the engine was billed as the Dauntless V8.

I have a 68 Buick 350. I think vin may be up around the water pump. I will go check my shop manual tomorrow night. You could also look at the engine block deck just behind the back of the heads. small wire brush in hand.
