Tech Question
Rory Groom, Silverton, OR, 1975 Dodge w200 Power Wagon 360
I am about to drop a 1966 440 from a Chrysler 300 in my 75 Dodge Power Wagon which is currently a 360. I was wondering if all of the electrical connections are going to be right for the bigger engine? Is there anything that I will have to change for this 440 to run properly in this truck?
Thanks so much for providing such a valuable resource for us do it yourselfers! Very much appreciated!
Rory-
Other than the usual cooling, exhaust, mount, transmission issues, it should be straightforward. Assuming you'll use a stock mid-'70s 440 electronic dist., the electricals will be a cinch. You'll also want to swap to a '70-up isolated-field alternator; if your '75 has the same style alt., that should work.
Overall, this swap is of questionable merit though. The 1966 440 was high compression (requiring today's pump 93 plus some octane booster or a dollop of race gas), doesn't have hardened exhaust seats (meaning the exhaust valves will pound in pretty quickly), and has a very mild cam and the worst heads ever put on a 440 (which might be fine for true for truck uses, EG: towing, plowing, schlepping, etc.)
