Q:
What's the best amc v8 343 or 360?
Hey, i'm looking for running motor for my 68 amx in cleveland oh. Really just want to drop one in as cheaply as possible for now, maybe look for 390 or 401 later. Found a 2brl 343 good shape and running out of a 68 ambassador with borg warner automatic transmission and also found a 360 2brl with 727 automatic out of a 73 javalin. Is there a diffrence in smog requirments for these two motors. Originality aside which is the best and most powerful engine. Heard the 73 javelins took a big hit on horse power and where only pushing about 190hp. Think the 343 is gen 1 and the 360 gen 2 but don't know the diffrence. I still have the original 68 amx 343 and 4spd but in poor condition, thought I would just switch over 4brl manifold and get a new carb. Probably rebuildable but it's such a hassel. Hmmm what to do. Thanks

A: If you just want to get it on the road for now with minimal trouble then I would use the 343, if you want more power I would go with the 360. There is nothing wrong with the 343, but the heads don't flow anywhere near as well. You'll never get the older style heads to do as well as the heads on the 360. The 343 is just a destroked 360, they increased the deck height in 1970 to get the added displacement (290->304, 343->360, 390->401). Either way don't use an auto trans, keep your 4 speed! If you want to use an auto trans for some reason use the 727, the borg warner is an inferior trans. Yes replace the Carb with whoever you like best, holley or edelbrock.

A: I would go with the '68 and keep things simple, especially if you are looking for a larger cube in the future. I've had two '70 AMX's, both with 390's and it is a tough motor. But, so is the 343 and I would probably be thinking the same thing you are, driving the car now.

Q:
will the transmission from 1968 amc ambassador w/ 343 v8 fit in a 1968 amc rebel w/ 290 v8?
(asked by Amanda K on July 05, 2006)
A: Yes.
The new-generation AMC V8 was first introduced in 1966. It is sometimes referred to as the "GEN-2" AMC V-8. All three engine sizes (290, 343, and 390) share the same basic block design — the different displacements are achieved through various bore and stroke combinations. All blocks share the same external measurements and thus can be swapped easily. Contrary to a popular myth, the AMC V8 was not built by Ford or anyone else. They did share some electrical parts (starter and distributor) with Fords, and some models used Motorcraft (Ford) carburetors, but the engine design is totally different. Bore center measurement was kept the same as the GEN-1 AMC V-8 so that boring equipment could be reused. Other than that, this engine is vastly different from the GEN-1 model. The GEN-1 engine is physically the size of a big-block Ford or GM engine, and is sometimes called a "big-block". The GEN-2 is closer to the physical size of US made small-block V-8s except for the bore centers, which are the same as some big-block engines. There are no shared parts between the AMC GEN-1 and GEN-2/3 engines.
The GEN-2 AMC V-8 was first introduced at 290 in³ (4.8 L) in 1966. It was used exclusively in the American model the first year (some reports indicate a few late production Classics had 290s substituted for 287s, but that hasn't been substantiated). The 343 in³ (5.6 L) came out in 1967 and the AMX 390 in³ (6.4 L) arrived in 1968. These engine blocks were unchanged through 1969.
The head used during this time are the so-called rectangle port, named after their exhaust port shape. The 290 heads use smaller valves, 1.787 in (45.4 mm) intake and 1.406 in (35.7 mm) exhaust, in order to prevent problems with the small bore. The 343 and AMX 390 used the same larger valve heads, 2.025 in (51.4 mm) intake and 1.625 in (41.3 mm) exhaust.
290
The base 290 in³ (4.8 L) 290 produced 200 to 225 hp (149 to 168 kW) with a 2V and 4V carburetor, respectively. It was built from 1966 through 1969. It has a 3.75 in. bore (95.25 mm) and 3.28 in. (83.31 mm) stroke.
343
The 343 in³ (5.6 L/5622 cc) 343 has a 4.08 in. (103.6 mm) bore and 3.28 in. (83.31 mm) stroke. The basic 343/2V produced 235 hp (175 kW) and was built from 1967 through 1969. Output for the optional 4V carburetor version was 280 hp (209 kW) and 365 ft·lbff (495 N·m) gross. This version had a 10.2:1 compression ratio. (answered by 69 FstBck on July 05, 2006)
A: IIRC it should. AMC was pretty good about stuff like that. any good junk yard should have interchange books that will tell you or you could compare the casting #s on the trannies.

Q:
AMC Ambassador SST questions?
I just bought a 69 amc ambassador sst 2 door hardtop with 62k miles on it and 343 v8 engine. where can I get parts at? Also, do the
wheels interchange with other makes? What would one of these in original condition, running and driving and good overall shape be worth? Any other info I might need to know?
