More torque (displacement is torque).
Parts actually, you know, AVAILABLE. (Nobody makes 413 pistons anymore.)
Better heads.
Most had a ThermoQuad from the factory, saving the trouble of changing over.
Crank is a wash, unless it's a 440-3, which uses the 6-pack crank & rods. A 440 block (any 440 block, from the 60's to 1978) is plenty strong for any street engine. Give me a 440 over a 413, every application, every time, no exceptions. Heck, I'd rather have a 400 than a 413.
And yes, shrouding (or clearance, on some aftermarket heads) IS a factor with big-valve heads on a 413's smaller bore. The best thing about a 413 is you can sell it on eBay and bolt in a 440 with no other modifications. There is no Earthly reason to use a smaller-displacement engine with identical packaging.

You are WRONG ...in so many ways. And WHERE in the heck do you get your info ? .....
No pistons ? .... there are many sets of NEW pistons available.
Better heads ? .. the 413 ? --- YES. They are MUCH better heads for the RV application. ...... better cooling capacity, valve size and quality, seats, angled plugs, valve rotators - ETC. The 440 head does not hold a candle to it... PERIOD.
The TQ carb ... it is a bolt-on deal.
The normal 440 block ? ... is in no way comparable to a 413. The 413 is a TRUCK block -- compared to a 440 "car" block ? ....what have you been smokin' ? You would rather have a 400(that are famous for thin-wall-blocks) to a 413 ? ...THIS just SHOWS how much you know about Mopars.
And you can just BOLT-IN a 440 ? ... in a 413 RV application ?? .... WrongO again Ford guy !
STICK with your Ford school-bus .... we are talking Mopars here.
Your blow-by special with worn-out-heads needs some severe Rx.

Your oil-burner needs help badly. My worn-out 2.5 in my Caravan gets 2500 miles per quart !
Run circles ? .... PUT your money where your MOUTH is !
he-he-he ....... so your Ford Escort is faster than that 440 of yours?

WHY do you avoid the Q's at hand ?
But I will answer YOUR Q..... the 440 was a way CHEAPER motor to build ....by a bunch.
And in NO WAY is the 440 a better RV/truck motor.
