Guys, I'm trying to settle a disagreement. What years were the magnum 440's built? I am figuring 67 to 71 is about right. Have a guy with a 1980 motor home with a 440. I have seen other motor homes with 440's built and registered as late as 80 or 81. This guy is convinced that he has a magnum just because it's a 440 and I'm trying to prove that is not the case. Chevy guys should not reproduce.

I agree with 67-71, it was the hi po version that Dodge labeled the Magnum

And...any Magnum will be stamped HP, something his bedroom barge motor certainly lacks.

A 440 magnum was just a 440hp. They made the 440hp until the end of 440 production. Magnum didn't signify anything specific, it was just a marketing term, one that they stopped using once the emissions rules forced the smogger era pistons into the 440's.

Yeah, but I seriously doubt they installed an HP engine in a motor home.

They didn't.

Correct, that would have been counter productive. The base 440 would have been better cammed for a motor home. You just found one of these guys who thinks he's got gold. A lot of em out there it seems...

It's probably the same guy that previously advertised a Max Wedge 413 from a motor home.

its marketing term,

same as 440 tnt Chrysler 440 super commander plymouth

it's about like every goober with an 86-93 mustang gt swears on his mothers good name that it's got a BOSS 302 in it?
