I am continuing my quest to document as many original 340 engine details as I can. I am starting with 70-71 engines and will work on other years as the opportunities present themselves. This thread pertains to documenting known original parts that are from the same engine, correct casting numbers, part numbers, date codes, etc. I have been studying and recording as many as I can before the most original examples are no longer around for reference due to restoration or replacement parts,etc. The most complete/survivor cars offer the most complete and most accurate information but those cars are exceedingly rare so I've been breaking it down to sections (engine/trans/rear end, etc.) in hopes of gathering more good detail and date code info.

Below are the known original parts found on one particular 340 engine I recently aquired as a complete and mostly unmolested original engine parts package, I have photos of all details mentioned and others as well. I have a second even more complete example I'll be documenting and posting on as well in the next few days.

If any of you wish to duplicate my efforts by submitting similar info. of your cars/engine/trans/rear details and wish to add it to my data base I would welcome it. Please feel free to contact me, I'll help you out if you need it. I will keep your cars/parts info private if you so desire.

Thanks!
