I decoded my 283 SBC. It's a '59 model purchase as a bare block. My question is: Were all 283's running the short style water pump? I bought some pulleys and the one for the pump seems too "deep" to fit. Also, what style of started would I need to go with? I know that they used the 153 tooth flexplate, but the block is at the builders and I cannot confirm if the starter is the staggered bolt pattern or parallel.
