I have a 340 (year unknown) with a 727 trans. I have a 650 cfm Edelbrock Performer carb and headers. Other than that it's stock. I plan on using it as a daily driver. I currently have an aluminum manifold that has a MOPAR marking but no part numbers. This manifold has only one source to measure water temperature. I want to add an electric fan and fuel injection in the future. I don't want to cut into the hoses to add an adaptor. Also, I couldn't find an adaptor that will take a 3/8 inch temp sending unit. Does anyone have any recommendations for good performance and provide the temp ports I need? Thanks

Post a picture someone might know about it.
Non T/A block 68-73,2780930-340.
The casting date is above or below the casting number on the side of the block, which is at the back side of the block. Secondary codes are also on the block at the front drivers side below the head. You will find a number like this:
F340P0018 10 16.
340 engine decoder??
Can anyone please help deciphering this Cuda 340 engine..I knew it was not numbers matching but was asked what year code it was and couldn't answer, what I think is a pertinent question if I decide to sell this car. There is the casting number on driver side which tells it's a 340...

Just drill & tap a hole into the water crossover or weld in a bung
According to the casting marks and the numbers on the heads indicate it's a 340. I took a photo of the casting numbers but I can't quite make the numbers. Thanks
According to Summit racing and a member of this forum, this part won't fit. It's designed for a big block and I was told that the big block thermostat housing is different.. Thanks.
Here I are the photos of the casting numbers and numbers from the head. I bought this ca about 2 months ago. It was originally a 383. It was converted into a AAR clone. I'll try to send some better photos. Thanks
The big block and the LA engine use the same thermostat housing, I have a hemi and a 74 318 and both have the same size thermostat housing. It's the magnum engine that uses the smaller thermostat housing. The bolt hole CL is 3 1/4" on both therm housings. Unless you have a magnum manifold on your 340, and it has to be one drilled for LA and magnum then maybe you are SOL.
