Ok, we've had threads on 1971 and earlier 340 engines but things changed a lot after 1971.

Later small blocks are very poorly documented and we need to document what originals remain for the future.

Let's see some pics of ORIGINAL details from your engines (no restored or repainted engine pics please, factory paint only). Any details you have would be great, paint details especially, please post as much info about the cars they came from as possible.

I have a bunch of pics of a 73 340 automatic a/c Duster. Non-california car.

Great pics Steve!

1974 Plymouth Road Runner 318 auto california emissions. Had headers put on it early in life.

I've seen that one on person. Have any pics of the engine mounts on any of them?

Don't forget to leave plenty of casting sand in the coolant passages!

Had more than one '71 block that would overheat due to a clogged radiator because of this...
