So I am very confused. I have put a lot in this motor and I get a horrible outcome. I have. 3.8 229 CID v6. When I start the engine it starts right up without a problem and sounds great at idle. When I accelerate the engine hesitates horribly. So far I have done just about everything the this engine. New pistons and piston rings, honed the cylinders, new gaskets all the way around. Every gasket there is on this engine is new. The heads were shaved to make sure they were strait and I was told the valves were in good condition. I still have this problem when giving it any gas. If it makes any difference with it being on land please let me know. But in any case everything mehanocal has been done. Any help with this issue will be great. Please help I am at the end of my rope.
