My philosophy has been that big heavy vehicles need high torque low RPM power. Light vehicles can get away with ricer style high RPM engines.
I am a little surprised the hemi did as bad as it did. The Durango isn't nearly as heavy as a full size truck if I recall, more like a car. But from the reading it sounds like there is a lot of drive train loss. Oh well real life experience tells the truth.
Just my opinion.

Nah, the Marauder had nearly 320#'s of torque..
albeit at a higher RPM.
The Marauder suffered from a TIGHT torque convertor, TALL tires
and tall trans gears, but still had better numbers than the LT1
Impala by a few tenths stock.........though it should have been better considering the Merc was a 10 year newer vehicle.
Realizing it's not stock but 4.10's, a loose convertor, a tuner and
the Merc destroyed the chebby.
I still miss mine....but it would have taken a Trilogy blower, Baer brakes
and the above mentioned mods for me to have kept it.

Hmm a bunch of the guys at NAISSO would dispute that but then that is what modding is all about.
The Car and Driver results from a few years back showed the Marauder as being slightly slower in the quarter, slower in the passing test and since it was goverened to prevent shaking apart(drive shaft vibrations they said), the Marauder stopped running at about 120 while the SS almost as a minimum would do 140 and then some. C&D was not generous with the Marauder and they mentioned that for 10 years newer and on paper it should have killed the SS, but didn't. More of a nicely tarted up Crown Vic more comfortable than the SS I think they said.
Very minor mods like cold air and maybe a chip improved the beast a significant amount. Standard gears were 3.08, a minor change and away they went. Some of the guys liked to play with Porsches on the Autobahn, and more than a few were clocking very good numbers at the track. Pretty good for an all iron, pushrod engine pushing a tank.
My SS was totalled in a rear ender and I still wish I had it.

You guys make me laugh with all the drag racing stuff.
If a Titan or Tundra or Hemi 1/2 ton wants to mess with my V10, all I say to them is "lets go!..right to the gravel yard, load up 4000 lbs of sand and THEN we'll race."
Kinda makes 'em think about squashing their wannabe trucks. It also just proves a point about what trucks are REALLY for.

I'll admit the 1/2 ton Rumble Bee and Daytona can roll, but i love how they got no problem goin after F-150s and heavy F-250 n 350s but when a Lightning shows they slow rite down. I lit up some guy the other day he had some kinda mazda pick up must have been messen with me for 5 minutes till i gave him a length and let my 460 talk for me, that slowed him down. I'll give alot of credit to that cummins diesel, my buddy has one with an intake, chip, and 4 r 5" exhaust n he taught a WRX a lesson. but uh yea Ford gasser motors just live longer make more torque, mine doesnt make much hp but i'll fix that, and that hemis getn better just its not there yet n ford will be right back in the diesel race when they get back with international in 08

I do enjoy seeing that eveyone seemed to ignore your post about the srt-8.

Gotta find that test...........published 1/4 mile times I've seen the Marauder was always a few tenths faster at around mid 15's. And and the track I beat my neighbors SS fairly easily........She was able to more easily smoke the tires I'll concede.
Standard grears wear 3.55's.........but I think the 18" tire and wheel combo took away a lot of that leverage.
Cheap **** Ford........the standard Crown Vics with 3.08's would do mid 130's.
Ford goverened ALL Panther platform cars (including current PI's) with 3.55's to 120
An aftermarket driveshaft (or balancing the stock one) let the car run where it was supposed to.
One HUGE difference between my friend's SS and our Marauder was the squeeks and rattles in the Chevy were horrible..........but the fact it was 7 years older probably had as much to do with that as build quality.
Will always agree that the MM was a weak effort and could have been so much more but Ford...............nevermind.

In 1957...the famous 392 hemi was introduced...it was gone in 1958...but talk about power! The 413 wedge replaced the hemi in 1959..
Hemis were re-introduced in the late 60's by Chrysler...but I don't know diddly about them.
In 1955 Citroen introduced the ID and DS 19...which also had a true hemi...a 4 cyl.
