Hi Ihave a 1976 Dodge dart lite spirit of 76,and I have decided to go bb,I do have all the original parts and motor and wanted to get started on the motor,I wanted a 440 but im having a hard time finding one in my area,I have found a few 440s from 1975 to 78 but nothing older,I did find a 413 wedge engine,what do you think? its complete.and affordable..

but the 440's are not complete missing exhaust manifolds,brackets and have a few broken studs.
 
You will spend more on a 413 due to odd piston size, but get less performance than the 440.why not get both engines and put the forged crank and rods from the 413 into the 440 block. Then you have the best of both worlds.
 
Pistons for a 413 are more expensive and harder to get. You'll need customs for anything really performance minded. I'd use the later 440 myself. Get some cheap hyper pistons, have itn internally balanced, and go have fun.

That was my thought also.The 2 together will be a good build.
 
are you just trying to get down the road or be performance oriented? what about throwing the 413 in it for now and build a 440 on the side for a later swap?
 
I would like to build a good strong motor,it seems the 413 may be a bit more to build,I want it to just be a down the road and have plenty of torque,and want my build to be a bit off the wall as well,seems the 413 block was a stronger block not that a 440 is a bad engine we all know its not but how cool would it be to have a 413 with a mild build under the hood of this dart that's a bit off the wall to start.
 
The blocks are no different than a 440 aside from bore size and I'm guessing there won't be any extra thickness because it's a 413 rather than 440 bore. I could be wrong - I haven't ever tested one but that's my gut feeling.
 
you could get a set of hypereutectics from summit for a 413 for about 350. Not sure how that would compare to the 440 piston price. There is nothing wrong with the later 440 blocks from 75 on and in fact, some have proved that they are indeed thicker. wether that is 100 percent true is up for heated debate sometimes. Any big block in an A body if set up correctly is going to make it into a rocket. However a bit nose heavy unless some time and money is spent on lightening up the whole deal (hedders, aluminum intake, aluminum heads, manual gearbox etc. How about this idea, a 400 block with a 440 crank. Somewhat lighter and just a bit easier to fit. and it comes out to 452 cubic inches or thereabouts.
 
You could also look for a 400 if you are rebuilding what ever motor you end up getting. Same also applies about combining the 413 internals in a 400. Have the journals turned and end up with more cubes than 440 in a smaller package. Good luck with your search.
 
Also remember the smaller bores shroud the valves, hurting performance. If I went to look at a car that had a 413 transplanted into it, I would not be interested. I would think they took whatever cheap BB they could find and stuck it in there.
 
DUDE!!! They made less than 1000 of those cars! Assuming that it is in relatively good shape and has original parts, that car is worth WAY MORE stock.

Before you tear it up, would you think about selling it? PM me.
 
I don't think a 413 cross ram built right is a cheap motor. Shroud valves? do you build engines with whatever parts you find,Build it right the 413 still is a great motor and still used on the street and track today for the bullet proof block.
 
I put my stroker440 (498) in my 1965 Dart GT back in 94 and just to be different I changed it over to a 4 speed. Used mostly stock linkage had to modify the fork.
Made my own headers. 11:40 / 121 1/4 mile, runs on 93. Street driven 98% of time
 
Guy at our track runs a 413 in a scamp. runs 11.60's on a mild build with 3800 stall and 4.56 gears.
 
That Spirit of 76 looks real nice in the photo.
Have you considered going small block. There is alot you can do with a small block.
You could go with a 430 cu.in. from a 340 block or budget build a 390 from a 318
Using a 4"stroker crank
and a pair of 340 J heads. Maybe deshroud the intake valves.
The 430 would require a 4.125 crank in a 340 block.
It would keep the car somewhat more factoryish and you would have something different. Also it would fit better in that A body. Headers would be easier to install.

Other than being forged 413 crank, why the 413 over the 440 crank?

This peaked my interest. You can use a 440 forged crank or a 413 forged crank in the 400. What's the difference in the two if you put them in the 400?
