Does anyone here have a list of engines they can provide that can be used in a 1999 Plymouth Neon? Looking for an engine I can work with, the stock motor isn't doing it. It doesn't matter what type of order you have them in, or if it requires modification. Also, side question. What is dohc and sohc and does my next engine have to be a dohc since the stock motor Is a dohc?

 

A google search would have been faster.
