I have a good running Ford 300 6 cylinder engine with an sod overdrive automatic transmission bolted to it that has 188k on it . It's going to be out of a 3/4 ton Ford van that an oak tree got a hold of and squashed it up a bit. Both function as they are supposed to I want 500. For the engine .300. for the trans.750. for both. And I will stand behind them for 30 days. Thanks. (530)983-74one8
