440 vs 413

[dw413]

When I first built my 1964 Polara, I had access to a 1964 New Yorker 413 that had been rebuilt, but never used, to replace the Canadian 313 that was in it. Over the years, I picked up a set of used 426 Street Wedge pistons that were advertised in Hemmings. We drove the '64 Polara so much, that the old 413 was eventually getting blow-by. I bought a 440 from a friend, that had very low miles on it since a full rebuild. This engine is in my car now. At this same time, I was restoring a 1964 Polara 500 convertible. I had my old 1964 413 block bored out to fit the 426 pistons I already had, and assembled my engine as a 426 Street Wedge clone. This was all 30 some years ago, and chances of finding stuff (pistons) to rebuild a worn 413 have greatly decreased.

Red engine is 440 dressed up with 426 Street Wedge chrome valve covers and air cleaner. Big blocks of this era were red in Canada.
Turquoise engine is '64 413 poked to 426 with chrome Street Wedge valve covers and '62 300H intake and carbs.

Do you have a source for the oval, gold Air Cleaners?

The ones I had were fibreglass repro's. I no longer have info on who made them, but I believe he was in Arizona or New Mexico. He advertised in Mopar Collectors Guide. Some one on this Forum has real steel ones for sale.

Hello all. I have an opportunity to pick up either a 1965 Imperial 413 or a 1966 Imperial 440.
I want to put one of these in my 1966 Charger. I know that the 440 might be the better choice. But I think the fellow wants a little more for it.
After a little reading, I see that the HP difference is minimum (340 vs 350) in these applications. Hell, maybe I get both.
Thinking simple bolt on upgrades at least for now. New carb, intake, and MSD maybe. Just want a reliable car and a little power for fun.
Thoughts on which motor. And suggestions on what’s the best plug and play carb/intake. Thx!!

Anyone know a quick way to KNOW if this is a 413 or 440? (Motorhome in Alabama).

Thanks to all, and HAPPY THANKSGIVING 2024!

Industrial 413 . Look at the waterpump.

Scrape the grease off the engine ID pad (the flat horizontal machined spot on the top of the block right behind that water pump). Might take some wirebrushing too, but you'll see either "440" or "413" and some other letters/symbols stamped there. I'm 90% certain it's a 413, which is still a great starting point for an engine if you have decent 452 or 906 heads around.
