I just bought a 1994 Chaparral 1930 SST with a Mercruiser/GM 305. When I bought the boat the current owner explained that the boat was winterized and the engine block still cracked. Upon looking at it it is more than a "crack" I have since purchased a long block to replace it. The company I purchased the long block through sold me on upgrading to a 5.7 from the 5.0. I upgraded some of the internals to give me a little more HP. What do I need to do for the fuel system in this case? It is the mechanical fuel pump with I believe to be a 2 barrel carb. If I upgrade to a 4bbl carb where do you recommend me getting the intake and carb? Also will the stop mechanical fuel pump still work or do I need to find a high volume one? Thank you and stay safe.
