the little car that could
for 3 900 $ you have a lightly modded 5.9 magnum thats easilly pops 400+ hp and 440 + ft-pd of torque , hands down , here in canada , i dont imagine in usa .. even more cheaper !
Well a junkyard jewel 360 is going to require going into the motor to get 400 HP. The crate 360/380 HP motors have higher compression pistons and a hotter cam. So basically you are talking about a rebuild so you are looking several thousand dollars.

Im sorry my man , but my best friend is an v8 engine builder since the last 21 years , and he s a mopar la engine specialist , and the regular 5.9 magnum in the trucks for example is exactly the same compression and heads than the 5.9 380 -390 hp mopar crate engine ,, so to make 400 or with a 5.9 magnum is really easy , and its the best street strip engine in the small block familly , fiability , low end torque , good hp and its verry easy to modify as so it is so simple ..fuel , air and spark .. thats it
a lot of people dont even know what is a 360 5.9 mopar crate engine ( its a underdog ) or what it can achieve , it is a verry respected engine fo those who runs at the dragstrips ..
and even a 318 magnum , can be verry dangerous if its well done , put some aluminium edelbrock heads , port them ,better valvetrain , and a good set up of cam , carburator , and intake on a 360 magnum and a modded new hemi is just as equal or better ,, theres nothing special about the new hemi , at least you have technology , fuel economy , but still your problems ar not gone ... more you put money , and more you got result ,, thats it .. if you have money.. do it ,, but it changes nothing if you want to save on gas , with all the money you gonna pay to do the swap !
Just wait a couple years. When the prices for new Hemi parts come down to agreeable levels, there won't be a good reason not to go with one. Engine builders are just barely scratching the surface of the new Hemi's potential, and so far the gains have been astronomical. In a little while it'll be cheaper to build a 450 HP 5.7/6.1 than a 450 HP 5.2/5.9. Plus, what about forced induction? I may be wrong, but it's not very common to see LA/Magnum engines with any good amount of boost unless they are fairly built up to handle it. The new Hemis take superchargers like fish to water (as do the Hemis of the past). If you guys are using the argument that they aren't that different than the V-8's of yesteryear, then why not use them if the price is right?

Every thing I have seen about the crate engines is the 300/320 HP unit is a tuck long block. Besides the unique cam and intake the 380/390 HP engines have higher compression pistons. Even Mopar Performance advertises that the 380/390 HP units have 10:1 compression pistons. They come with a 288/292 cam and a 9:1 compression wouldn't be enough to maintain reasonable cylinder pressure for acceptable low rpm torque.
The magnum crate motors are very good and can make a lot of power, they just aren't as good as the new hemi motors and within a few years they will be competitive price wise with the magnum motors.
Not sure about just scratching the surface... I know all the major engine builders that have put out strokers or all kinda and of course the forced induction stuff as well. These guys can get u a balanced rotating assembly for $3500 w/very good parts. Forged everything.. custom pistons, profiled crank, tapered rods, etc.....
Kind of shot your self in the foot on that one. Taking your numbers;
$1500 for a used hemi (for that price it will be relatively low miles not
requiring a rebuild).
$ 200 for a cam that will push the power to an easy 450 HP (been done many
times in the magazines).
$1200 for headers and motor mounts.
$1000 for an aftermarket EFI controller
For $3900 you have a 5.7 in your A-body that is making 50 HP more than your rebuilt 340 and still can go to 500 without much additional work.
good thing , for me a old 392 hemi as it place in the duster better than the new hemi , anyway with time .. its a question of opinion ,,, theres people who understands me and others that doesnt ,,
its your choice ,,, im laughin lound when i ear someone who wants to swap a 3g hemi in is 02 ram ,, and still as a 360 , 5.9 magnum in it ... there is so much potential is this engine but nobodie cares ! ( huge underdog )
me im a too big fan to take the 5.7 or + hemi to do a ( hemi car ) in my mind a 70-74 cuda with a 5,7 hemi will never but never be a HEMICUDA , or same thing with a 68 dart ,, it made history with the old iron , why destroy that .. anyway with time i realise that i have my opinions and you got yours ,, so thats mine , and its better to stop that thread !

so you are saying that the the newest mopar performance catalog is misprinted? and the spec. sheet that came with the 360/390 crate that I just bought is misprinted? If they are wrong, thats great to know. But everything I have on it shows that it's a 9.0:1 compression motor with a 288/292 dur. cam with .501/.513 lift
