I will agree with the 1977 FSM, listing for both 413 and 361. This battle is getting bloody, I do have a 1979 440 block in my race car, yes a 79 block. Ok, I drank a lot of beer today, close to a 18 pack spead between Hams, and Grainbelt. I seen something I though was interesting today, no it wasn't a UFO but very close. I had a guy stop buy the shop today driving a 1997 ram 2500. That was biult with 6 bolt wheels and even had a non-magum 360 factory installed in it. No air bags, a fancy little bottle jack that a Chrysler sticker on it. Everything under the hood was in spanish, some sort of mexican inported truck.

Motorhomes were built around a truck chassis....Dodge / GM / ??? ....With that being said.... What ever engines were available in the that chassis can be had in what was being built around it. So, IF a 413 was availble until 1977 in the larger Dodge trucks than surely we must believe that A MH could have been built using a 413. I'm not saying they were or not....Just pointing out that MH's are built around existing / available chassis' and their engines - Not the other way around. I "Never say Never" afterall..How many times has there been a car or option discovered that everyone said "Never" existed.

I have a 413 66 and a 361, anybody want to buy em?????????

I see this is an old post but I was wondering if you did have pistons made for the 413-1 ? I have mine torn apart now trying to track down some engine noise , I'm thinking about putting a new cam in it . Not sure if I can find a replacement close to stock, I gotta make some calls I guess, any camshaft in mind that would fit this motor?Anyway, Thanks for any input

Not sure how you thought reviving a dead 10 year old thread that was mostly a pissing contest was gonna help, a fresh thread would have done better, mostly because old Doc flappergasser will fire back up and this thread will turn too poo again.

That said any custom piston maker will make whatever piston you want. Or you could have looked at Summit Racing and see what they had.

Back when I redid the 413 in my 64 300 I ran the old DC Street Hemi grind in it. Basically it had the same specs as the Hemi but n a B/RB cam, P4452993AE is the latest version.

I took a 1972 413-3 short block in trade on assembling a 440 motor for a local customer, I ended up using one of Ma Mopar 4.15 stroke 8 bolt stroker crankshaft in it along with having Racetec make me a set of 4.250 bore pistons of a set of Eagle forged steel H beam street hemi rods I had from another customer who step up to a 4.25 stroke crank with a set of 7.100 long BB Chevy type H beam Molnar rods with the 2000 ARP bolts in them.
I'm going to use that motor in a 1963 Plymouth Fury project car I bought several years ago, tell the local GM and Ford guys it has a old 413 truck motor in it with a set of aluminum heads

I have a 300G and my engine guy has no use for cast pistons and had ross make a set. Not cheap but just what we wanted.

I had no luck finding any good used ones

I've used several 413-3 truck blocks in my racing days in my 1963 M.W Plymouth Belevere in NHRA stock class after breaking a rod and ruining the original 426 M.W. block
I did have them sonic tested and maganflux first, one of them may have ended u p being bore to 4.280 to start with, maybe not CRS I would have the crankshafts offset ground to increase the stroke .013
I'm not sure if the 413 blocks in the early 300 where special or not like the marine, industrial and truck blocks where later
I bought a 1957 300 C hardtop in in 1968 for $500.00 after getting out of the Army, that was out family car for a long time
I had a chance to buy a ready to drive1959 Fconvertible in early 1965 for $200.00 from a local garage in 29 Palms ,CA. I didn't because I liked the Hemi motors

Hay Snoopy .... that’s Duck FlipperMaster !

Reasonable replacement pistons are still available out there

$90 a piston for shelf stock isn't "reasonable".

I can buy pistons for less for my 218.

Snoopster..... 90 beans each ?

WHERE are you shopping?

I’ll sell you mine for 80 clams each and use that loot to put a hefty down payment on a canal lot in da Keys !

Did you click on the Summit link I posted?

No one wants used pistons for $80 a crack either.

Snoopster ... please fOcUs !

There’s a NEW SET on eBay RIGHT NOW for 399 all day long

And the last set I got on eBay was a cast set that was in a rebuild that went bad .... barely 20
miles or so ... a pig fat Berry carb ... among other things. Other than the piston pic - WHAT SPEC would you ask for ? THIS SET -!like 110$ !

Another set of NEW std bore 426 MW 11 to ones ... no pins ... 150$.

To the guy who doesn’t like cast pistons ... they are fine in a NA motor.

IMHO, the best thing to do with an Indust. 413 it ditch all of the guts and add a stroker crank to make a 426 wedge engine out of it. way cheaper than a real 426 wedge or max wedge engine now days.

and I do think it is all over the counter parts readily available today. that block is the [censored] for a cloning 426 max wedges.

0.02 $

You realize a 426 wedge is a .0625 over 413? Not sure anyone makes that tiny a stroker crank to turn a 413 into a 426.

As for the Ebay pistons, no link no exist.
