I'm getting a free 413 engine for free
is it worth to build
is parts hard to find ?

My parents new 1962 Chrysler New Yorker station wagon came standard with that 413 motor, never had a problem. Don't know about parts availability. From Wiki: The 413 RB had a 4.1875 in (106 mm) bore and was used from 1959-1965 in cars. During that period, it powered all Chrysler New Yorker and Imperial models, and was also available on the lesser Chryslers, as well as Dodge's Polara and Monaco, and the Plymouth Fury as an alternative to the 383-cubic-inch B series engine and/or the 318 Poly. With a compression ratio of 10:1, it developed 340 brake horsepower and 470 lb-ft of torque in 1X4-Bbl trim.

nice car
rare
Summit carries Speed Pro hyper pistons for the 413.

Many of the parts are interchangeable with the 426 wedge & 440.... (Except bore related....)

413 - 426 wedge - 440 all have the same stroke...
You can interchange cranks, oil pans, oil pumps and pick-ups, heads, intakes, exhaust manifolds/headers, timing chain, timing chain cover, water pump, valve covers between them... Like I said - everything but bore related parts... They all have 3.75" stroke and same deck height...

thanks
Be careful it is not an industrial or motorhome engine. They have hermorphadite heads that you will not want to use.

This is easy to tell, "high mount" water pump, and usually instead of the center heat riser passage being hooked to exhaust, it goes to coolant, and they seem to use "Ford" huge 18mm thread plugs. Some have 6 bolt, others have 8 bolt cranks. Other than the water pump/ heads/ intake the block and crank are OK. There are both 413's and 426's made this way, I don't know about 440. One nomiker is "426-3"
High mount water pump
See the water temp probe in the middle of the exhaust? That is COOLANT there, and those ports are different. The intake heat crossover is also coolant
Pistons are expensive.
Rest of the parts are standard big block, if the motor is out of a car.

My brother was running a 413 in his Dart Sport with a 4 speed, ran great
IF it is the industrial engine, isn't the block the same as a standard engine?
Yes.
Summit has them for 339. See the link I posted above.
Thanks Bobby. I figured as much BUT you never know. With that said, I'd follow the Summit link for the new slugs and start in right away.
The best thing about a big block are really nice head/intake choices that work really well with the increased displacement over the small blocks.

wonder how far a guy can safely bore a 413 .???on the average? put a set of cnc`d alum. heads on it, a stroker crank, you have an over square stump puller.
Try this
Well, there was this gawd awful thing in the early sixties called a MAX WEDGE 413. I "hear" it set all kinda records. lol
Check out Falcon Global. They offer the flat top. It's cast, but it's high quality and has coated skirts.

Before Ebay and forums/internet, I used to strip 413s for the heads (516, etc.), crank and rods, and scrap the bare blocks. Wish I had saved them now for some quick (local pick-up only-lol) ca$h!! The concept of paying $500 (back then) for cast pistons to have a tiny-bore 440 just didn't appeal to me. Doh!!!
I like the idea of a 413 build. It is nice because they can use the bigger valves that even a stock head offers over the small block. And Lord knows small block guys can use all the port and valve they can get on there 4.00 (and bigger) arm strokers! Truly more the merry for those engines.
The newer intakes available are just great as well. Trick flow top end and a roller cam equal high rpm screamer ... if so desired.....

OK, with all of that said, here's my 413 tale. Back in 1978 I picked up a motorhome 413 for cheap money with low miles because the motorhome burned down around the motor. I thought it was a real good deal. HOWEVER, I found that the motorhome 413 was the industrial\truck version with the cam that ran off of a big gear backwards. No timing chain. Anyway, I tore into the engine and the block was real tight with zero wear and damage. Good? Well... The pistons had massive dishes so compression was like 7:1 or something close to that. They got junked for new standard bore flat top 413 pistons (available from the dealer at that time). The heads were no good so those got tossed for junkyard 440 heads that needed rebuilding. In fact, the only thing that didn't get tossed were the block, crank, rods and a few nuts and bolts. Everything else I had to salvage from junkyard 440's. That included things like the oil pump, timing cover, balancer, flywheel, oil pan, dipstick, pulleys, used intake, new timing chain and proper gears, camshaft, lifters, pushrods, rocker arms, distributor, drive gear, valve covers, water pump, pump housing and a LOT of other stuff to make it work. In the end, I had a nice motor that was down on cubes but if I'd done my homework, I would have passed on it and went for a 440. I still have that motor though.
If I had to do it again, I'd walk away from the 413. If it's free, I'd just use it for parts.
I also notice someone has posted a link to new 413 pistons, BUT, those are the dished low compression industrial\truck motor pistons which means if you use them with the larger chamber 440 heads you're going to be down in the weeds compression wise.
