Ok guys, come spring or summer its gonna be time for me to start putting my dodge back together and hitting some trails and mud with you all, instead of web wheeling all the time.

Right now I have a 360 in my truck which is going to require a rebuild (Leaking oil from everywhere and has been sitting for nine years), and if I pull the sucker its gonna get some go-fast parts to make it worth my time. [36]

But I've found a 383 for sale, .030 over with about $4500 worth of parts put into it, already built and ready to go, and he said he has the proper bellhousing and motor mounts to drop it into my truck. $2500 for it all and a corp 14-bolt rear, and whatever else I want from a 78 RC :confused0006:

That being said, I've always been a Big block kinda guy, so the idea of jamming a 440 under the hood is always kicking around in the back of my head.The problem with a 440 is I'd have to buy it and start from scratch as opposed to having a complete 360 or 383 to go from. :dontknow:

My budget for the motor build is $2500, So the 383 is probably my best value, but I'm always open to suggestions.

And if anyone can give me some stock power numbers for the engines, I'd be happy too. Thanks.

well, personally I like the 383.

And, i've seen 383's that will outperform the 440.(HAR DO BELIVE I KNOW).

You muar weigh the differencees. Big blocks are HEAVY. Torque,,,, nearly unmachable. But close.

What kind of wheeling are you doing? If you are doing 44 and bigger tires, and deep, snow, mud.. then maybe the 440, but for a trail, all around rig.................... i'd take the 383. (I just like this motor)

no,383 is a small block

Yeah, a 383 is Mopar 361-383-400 family.

:confused0006: I'm really aiming at all around; I like the size of 36" tires, but I won't knock out 38s in the future. I mostly wheel trails, but I do like mud and such too. Truck is still gonna be used for truck duties (Trailer pulling, moving chit), so I don't want it to be completely outragous.

38" swampers or boggers aren't outrageous. a 44'' tire is small compared to todays wheelin standards. Buy a good rebuilt motor, new meats and wheel the thing until it breaks, then upgrade.

I don't want to buy a rebuilt motor, if I'm going to pull mine I'm gonna do it how I want it. Everything is already pretty much where I want it, thats why the engine is next on my list. The only other thing I should do is bodywork.

Well i have gone down this road before the whole how much does it weigh to the benefits if your gonna spend the money get a late 60's early 70's 400 big block and put in the 440 crank with some short top pistons from Keith Black (Not that expensive) you end up with i believe a 472 cubic inch that now really likes to rev .......now you got all cheap parts and big power on the cheap .............Now thats just a thought but it's something i always waned to do

Maelthra
12-01-2007, 10:44 PM
hmm, thats a good idea, I'll look into that too. Thanks.

no,383 is a small block

383 would not be considerered a small block mopar .
smallblocks would be the 273,318,340 and 360 LA engines

the 383 is a bigblock B engine (low deck) and the RB was the high deck big block 413,426 wedge and 440 . they did make a rb 383 but for only a couple of years in only a few cars

If you want lots of torque a 440 is great ( I had one in one of my old one tons and it was great) just remember no matter what you build for a mopar big block it will cost alot in comparison to the ford or gm products.

I had an old tech artical burried somewhere in one of my book piles with the 400 block with a 5/8ths offset ground 440 crank ,buick BB rods (they are shorter) and i think factory pistons for 490 something cubic inches. it was a low buck way to get big power on the cheap(and ya wonder why it appealed to me:) ). I was actually thinking of doing this to one of my Cudas back when i was young.


you you want torque go with the 440 the 383 is a short stroke engine and has less potential for gobs of bottem end torque like a 440

you can use the stock rods on my application the way it works is the distance from the riss pin to the top of the piston on a 400 is huge and the stroke on the 440 is perfect if u use the short top pistons and you get stupid amounts of power and torque . Zoltans got almost 1000 hp with some head work on one

Barracude and Always broke, if you can dig up a little more info for me on the two options that'd be great, thanks.

I'm not looking for absolute gobs of torque, just something that I can use to do some work with when I'm not playing.

A nicely done 383 stroker is quite capable, just look at all those Chev 350s that are turned into 383 strokers.....gobs of power, enough torque but not too much.....that'd be my option plus it's easier to slide a small block into anything rather than a big block.....more room to play with.

a 383 mopar is not a smallblock.

Nor is it a stroker. :D

12-02-2007, 06:11 PM
i though that 383 was a big block because it uses the same exauhst manifold gasket as my 440 and the one from my 360 is way differnt.

its a big block because its block is big:D

oh yea and another thing a dodge 383 is NOTHING like a fucking chevy for fucks sake!!!!!!!!!!!!!!!! not even close it ant no 350 stroked out its a real 383 cid not a stroker!!

Lol easy buddy haha.

I'm thinking harder about the 383...But that blows the shit out of my budget for body panels, windows, and other stuff. Oh well!

For the value with some shopping around you can do a good rebuild with a matched for application cam ,headers, exhaust , internals etc . If the truck is allready set up for the small block stick with the small block. a 360 is a good motor with plenty of aftermarket support. the money you will save by not haveing to buy all the parts you need for the bigblock conversion (and you will need other parts) can be better used elswhere on your truck.

The $2500 comes with everything for the swap, from motermounts to bellhousing for the tranny, etc.

Anyway, I'm still thinking about it. I'm going to try to go cheeck out the engine on sunday.

im with always broke, my uncle did it with edelbrock heads and on the dyno he got 693 horsepower but i think his was overboared to the max too so not sure exactly what the displacement was

Thanks you saved me from back handing my computer screen for the other stupid replies of it's a small block and/or a stroker.

FWIW, if I could spend the money I spent rebuilding my 360 which turned into about $4000, I would do up my 400 block, 400 rods and an 3.75" RB crank for a 451 stroker. I don't speak from experience with this engine combo, but I have never heard anything bad about a 451 stroker.

not sure how a 360 turns into a 4000dollar engine job? unless you have a shop do it start to finish . you can get complete rebuild kits with forged pistons for dirt cheap , the heads are very workable on the 360, intakes are cheap and you can find them second hand, headers are pretty cheap. all the parts for a pre 88 360 are pretty easy to find. you should be able to get it all done for less then 1/2 of the 4000 bucks. but if you truly want a big block getting one is the only thing that will cure the craveing because no matter what you do to the 360 you will probably always be left wanting.

Remember to try and find a pre 1972 400 block to start with it's something about strength in one area (an Engine builder told me) wich will make the engine more reliable

Lurker

Barracuda, yes a shop job for the long block including J heads, plus extra dough for full MSD ignition, and the extra goodies are brand new as well.

It all adds up quickly. Sure wish I had a lordco girlfriend when I was getting this stuff built.

The engine builder was prolly talking about the early 440's with steel crank and no emissions bs. the late model 440's have a cast crank and emissions garbag. the later models are still an alright motor but jus arnt the best. Im pretty sure pre 1975 440's had steel cranks. Oh and for an fyi, i spent about $4700 on my steel crank 440 on just parts. I did all dissasembly and reasembly. It was bored .030 over, forged 10.5cr pistons, hardened valve seats, and so on..

you Like "this motor but dont even know that the 383 is a rb engine=BIGBLOCK

Lucas
02-06-2008, 10:01 PM
the cost to rebuild a 383 or a 440 will be the same and iirc pre 72's have steel cranks not cast cranks so you can run some serious hp

you will not find a pre 440 core for unger $750.........hard to find all the mopar guys buyem up

78bronco
02-10-2008, 08:21 PM
stock steel cranks are good to about 650-700 hp and 6500-7000RPM now the rods are the crappy part

its nice to find one running and with 57,151 org miles on it a 440 in a 75 4x4 with all the goodys[36]
