360 engine vibration

From what I can tell that engine looks Like a carbureted LA 360 with Stock cast iron heads, mopar stamped rockers on one main shaft, with basic early mopar electronic ignition with the small brain box, and ballast resistor setup and early 12 volt ignition coil that bolts to the intake manifold.

And the front vibration damper is the little bit later style damper or a replacement damper and is the correct one for the external balance 360 engines. I like that style damper better than some that came on the 76 360 engines with the lopsided weight hanging out on them just behind the pulleys.

Although the placement of used AC brackets at the alternator could suggest a later style 360 just before the magnums, or suggesting that the brackets came off a magnum short block to begin with. The front balancer looks later 360 or magnum too when considering this.

Hot rodding cars anything is possible, It could be a magnum short block (black in color) and the silver unpainted water pump makes me wonder the year too. Possible they took a magnum short block and put early style mopar cast heads on it, like the J heads. This way they can go Old School Carburetion and Intake and heads, on the newer generation Magnum style short block.

(If it were a magnum 360 with magnum heads, the heads would have rocker studs coming out of the head for each rocker.) Hope this helps lead you in the right direction
