You need a 1942 or later flywheel to fit the 1957 crank.
There is also a slight issue with the exhaust manifold. 1939 head pipe dumps straight down. A 1957 235 dumps at a angle.
216 manifolds can be adapted to a 235, or change the head pipe. If you’re truck still has the splash pans between the engine and frame, this would mean the pipe will not go through the original hole for the pipe.
I usually used the 216 manifold on the conversions I did. This is best done with adapter rings in the head to accommodate for the size difference between 216 and 235 intake ports.
