Mike,

Thanks for your inquiry and the opportunity at earning your business. The Hp rating for longblocks is determined by the fuel system that’s install back onto the engine. For example since GM only produced one marine version of the 4.3L during this timeframe Mercruiser used this same longblock on their 190 Hp 2 barrel carb model, 220 Hp 4 barrel carb model and 230 Hp MPI model. Therefore the Hp you will see on a properly matched longblock will be the exact same as whatever your engine is rated at currently since you are reinstalling the same fuel and spark systems. What is the block code or serial number for your existing engine?  Let me know if you need any further technical information or help placing your order. In either case I will be glad to assist!
