The Service Manual should have all that information...

PS. I found this online which may be what you're looking for 'std' journal sizes. You also might need the min/max bearing clearances, etc.. which will all be in the service manual.

283 - 1957 through 1967
The 283 crankshaft was basically unchanged from 1957 through 1967 although different materials were used, nodular iron and forged steel, based on the application. All were a 3.00-inch stroke and have 2.00-inch rod journals and 2.30-inch main journals.

A 57 has a forged crank and a 63 later cast will not clear block.
