Scott, this is the best thread in a long time! Would you want any 69 info posted here? I am restoring a 340S fastback 4 speed and there is an original owner 69 340s 4 speed convertible w-factory air who lurks on here. Other than the lower rad hose, fanbelts, radiator, negative battery cable, plug wires, alternator and carb, mine was unmolested right down to the heat shield and all A/C stuff still intact.

Absalutely! Any year 340 is fair game on this thread, the more original details the better. It's a HUGE jigsaw puzzle at this point, every little piece helps put the big picture together.

* I discovered that most of the hoses that were on my complete 71 engine above are the originals, most stamps are still readable so I'll be posting pics.

Excellent detailed post John!

Thanks. Going over the dates made me think it must have been delivered just in time for someone who had a real special Christmas in 1969!

I added some info regarding the trans and K-frame. Has anyone else had a trans assembly date later than the engine assembly date and SPD? I wonder if they had a reason to wait for the trans? Shortage? strike!

I just took a 340 4-speed factory A/C drivetrain out of a 69 Formula S convertible, I will check the date codes out when I dissemble it and post them!

Thanks Jim....Also, could you note the finishes on the attaching hardware holding the A/C brackets, etc. onto the front of the engine, Black Oxide vs engine color, etc.

Great thread!

Cool thread!

RoadRunnerJD posted about a 69 Barracuda 340S fastback:

"Distributor Hold Down Clamp: Copper Plated"

I have a 69 340S also with a copper plated hold down clamp. But the copper plate on my clamp originally had a black coating on top, maybe paint - not sure. I scrubbed it with a mild abrasive, and the black came off.

Can anybody discuss details about this metal finish? Is it actually black paint over copper plate, or some chemical reaction on top of the copper?

I've seen plenty of discussions about finishes like zinc plating with chromates and dichromates, and phosphating, but I've never seen a finish discussed anywhere that had copper plate on steel with something black on top.

I was surprised too?? Hemi's and A12's with Prestolite dual points are not copper clad. Why is it like that on a 340?

On a 69, is the intake bypass hose to the waterpump painted?

Yes, all 68-73 340 4 barrel's should have a painted bypass hose

scott, when i picked up my 69 340 a couple of weeks ago, the guy was cool, and threw the trans in, with the deal. motor is complete except for the manifolds and fan (blewbyu somehow managed to buy from the motor.... ) and it's all there, including starter, alternator, fuel pump, carb, etc. can get you some numbers when i get it out of the trailer.

will ask the "a" body guys to post in the various forums, to see if anyone has the car for this motor, and if they do, i'd swap it for another 340. mine did turn over, and nothing seems broken/missing externally. mines going into a dakota, so the starter, intake and carb, alternator and brackets, dizzie, etc., may be available, as i wont need them. thats UNLESS someone finds the car to match the numbers, and the person actually wants it.

Cool beans! But trust me, you left the numbers matching car at the junk yard, 1969 was only when the block was cast, it was assembled as a 1971 engine and originally installed into that blue Demon.
