I just recently bought an engine for my 05 Dodge
Magnum hemi It came from a 2006 Chrysler 300 I
was told that i would be Able to plug everything up
but I’ve already noticed that my valve cover is
different is there anything else I would have to
Is it the same type of engine? If the engine is a different type, there are lots of issues. There is a large amount of work required when you replace a different size engine in a vehicle. Motor mounts, exhaust system, transmission, emissions, gauges, wiring, etc. All of this needs to be figured out. If you are paying a garage to figure all this out, it will be a very expensive endeavor.
