Mystery Engine
 

I'm trying to figure out what kind of engine I have in myautomotive class at school, but I can't figure out what it is. This is all the info I have from looking at the engine and doing measurements: It's a Chrysler v6 and the displacement is 4 litres(4037 cu.cm.) and it isn't very new, probably somewhere from 85-92(that's what my automotive teacher told me). If anyone might know what it is please e-mail me at superman1752@hotmail.comThanks in advance for any information and help.
