In May I re powered with a rebuilt 454, 7.4 had lots of power but could not get it to stop pinging no matter what we done after about 10 hrs on engine we called the rebuild shop and he said "use higher octane gas", we was using 90 octane the highest the docks sell, so I got octane booster and still pinging somewhat, with engine hatch closed and running you could not hear the pinging.
At 20 hrs #4 piston blew a hole in it.
After research the pistons installed they were a high dome made for a 1/4 mile dragster, the engine had 10.2 compression.
The builder knew it was for a 2859 Bayliner boat and should have known better than to build an engine like that, IMHO
After getting it redone with flat pistons I have lots of power and so far after 50 hrs no problems.
I ask the rebuilder if it was under warranty he said "no because it wasn't his fault", even after not telling us this engine needed to burn aviation gas.
I'm don't know anything about engines except they produce power but I had my grandson with me and he is a very good mechanic he had knew something wasn't right. He jetted the carb and even drilled the jets out to get more fuel, still no solution. He was on the phone with his machinist in Spokane and the final word from him was Dragster Engine not boat engine.
Does anyone thing I have any legal recourse? It would sure be nice to get some $$$ back.
Thanks
