Some of the ingredients in the newer 181's may warrant a closer look like the powdered metal connecting rods, will they also fit the 6's? Stronger and lighter than stock and cheaper than aluminum! When they came out in the SBCs' they were the hot ticket at the time. Also the water pump looks pretty good with the newer style seal. , http://www.gmpowertrain.com/Libraries/Marine_Engines/Vortec_3_0L_I-4_Marine.sflb.ashx
