Yes, I should have explained in more detail about truck 318 cranks. I was mainly referring to heavy duty applications having the forged cranks. Most of the light duty and automatics have the cast cranks. As with all the models I mentioned, sometimes a forged crank was used when a cast crank was unavailable at the time the engine was being assembled. All the trucks I pulled apart that had a 435 or 445 transmission, had a forged crank. The trucks and vans that had the 833 were a mixed bag. Some had forged, some had cast. It may have also has something to do with whether they were a 1/2 ton or 3/4 ton. I didn't pay much attention to that at the time. As for big blocks and specifically the 400, the manual trans applications used a forged crank......basically a 383 forged crank. Just like the 440, Chrysler didn't have a weighted flywheel for the internally balanced BB cast cranks, so they used forged ones so they could use the flywheels they already had on the shelf. The cast cranks in most cases weren't even drilled for a manual trans input shaft, let alone finish machined to accept a bushing.
