I had a 340 short block rebuilt in 2018. I pulled the engine this winter because the rear main seal and the timing cover seal leaked and a bad lifter knocked occasionally, for a few minutes after startup. I thought I might as well get the cam lobes checked since I already had the 340 torn apart...

Sorry to beat a dead horse yet again. In 2015, I read countless posts on the 1969 340 engine color. The vast majority of them stated that the 1969 340 was painted turquoise, therefore, that’s what I painted my 340 in my 1969 Swinger. In addition, as I recall, the 1968 340s were painted red, the...

I live in Jackson Michigan. I had a bad experience with an engine builder/machine shop in the Detroit area and I need to get my 340 short block rebuilt again. Are there any recommendations for a quality and reputable engine builder and machine shop within a couple hours drive (maybe even in...

I purchased a 340 dated December 1968. It appears to be completely stock and doesn't appear to have ever been apart. The pistons and rods have original casting numbers. But I can't find any casting number on the crank. The crank is a steel one and the first and last rod journals were drilled for...

I had my 340 rebuilt in my 69 Swinger. After 600 miles the clutch started grinding when the pedal was fully depressed. It turned out the Bell Housing was misaligned by .019” total and the clutch disc was hitting the flywheel bolts (the builder told me he aligned the BH as I requested). I should...

Has anybody ever seen anything like these lifter bores? The engine is a 1969 340. I'm wondering if this was a really bad engine casting and if this block is junk. Thanks for any input.

Does anybody know where I can buy a reman OEM starter for a 1969 Dart 340. I tried one from Autozone and looked at many pictures on the internet (Classic Industries etc) and all seem to have "ears" and bolts on the solenoid that hit the flange on my exhaust pipe where it bolts to the HP exhaust...

I am going to prime my 340 before I start it. I don't want to take my original valve covers off because I painted the engine with them on and I used RTV on the gaskets because the valve cover rails on the heads were not perfectly level. I think that each head receives oil in only 1 position...

I am having an alignment issue between my damper and water pump pulleys on a 69 Swinger 340. The width of the outside edge of the water pump pulley (at the V) measures 5/8". The damper pulley measures 3/4". So there is an 1/8" difference. Since there is no power steering or air conditioning...

I had my 340 rebuilt. When installing the water pump and damper pulleys I noticed that the damper pulley is slightly closer to the block than is the water pump pulley. It's hard to tell but maybe 1/16" or more. I didn't notice if it was that way when I tore it apart. It's a different block...

On my 340, I replaced the heads with 1.88 valves with 1971 heads with 2.02 valves. I was going to use the Felpro cork gaskets from the gasket kit, but I noticed that both heads seem high in the center, so when I push on one end of the valve cover the other end has a gap. Has anybody else...

I am going to paint my 1969 Dart 340 the original turquoise. Does anybody know what items were painted at the same time as the assembled engine e.g. water temperature and oil pressure sending units, heater and bypass hose fittings, the nut and clamp that hold on accelerator cable. I know that...

I was planning on using the cork gaskets on my stock 1969 340 intake. The machine shop didn't return my front and rear dowels. I purchased 3/16 dowels but they are too loose. Does anybody know if these are supposed to be 3/16 roll pins? Thank you.

I was intending to keep my 340 factory appearing, as is the rest of the car. I had it rebuilt and told the machine shop to install a new stock Mopar Performance damper. Instead they bought an aftermarket damper, with the timing mark and index on the wrong side of the engine and balanced the...

I am rebuilding a 1970 340 for the street, not for racing. My 69 Dart has stock a AVS, intake, 2.02 heads, and stock exhaust manifolds. It is a 4 speed with a 3:55 rear end. I’ve read that the compression ratio should be less than 10:1 to run on pump gas. I wanted to error on the safe side, so...

Can anybody identify this piston and the compression ratio? It's in a 1971 340 and it is at TDC. I thought it was going to be the stock one but I don't think that this piston would yield the stock 10 1/4 compression. Also I've read that a compression ratio of 10 is the maximum for a street...

I noticed a lot of crankshaft end play on my 71 340. It supposedly doesn't have many miles on it since a rebuild. The spec is .002 - .007. Mine came in at .033. Attached are pictures of the thrust bearing showing that the crank was thrusting forward and chewing up the side of the thrust bearing...

The casting number on my heads that are on my 1971 340 is 4343475A, which have 1.88 intake valves. After perusing some websites it appears that they are 1986 – 1989 360 heads. I read that swirl port heads were introduced in 1985, but I couldn’t determine if these heads were swirl port for...

I want to remove the 340 out of my 69 Dart so I can paint it. I have already removed the transmission to replace the clutch and PP. Do any of you folks have any knowledge about the safety of an engine lift plate that bolts on to intake manifold to remove the engine? Also I take it that...

I've checked some websites but can't decode the following crank casting number: 2868393. It also has 26 8393 on it. It is hard to tell if the difference between 6, 8 and 9 though. Thanks for any help.

I am looking into buying a 340 short block as a backup to my 71 340. The guy is going to get back to me on the numbers on the block, but he thought it was a 72 or 73. I believe the compression for the 71 is 10 1/4 and it dropped to 8 1/2 in 72. He didn't think it had the stock pistions, anyway...
