motor mahem

[thesmoother]

i have a 08 short bed ive been collecting parts to make it A SRT-10 clone OR queasy version of a viper truck. Its viper red with real viper seats , badges and other bits of interior, so far. i tracked down the panels/ground effects the wrap around the truck so that’s making good progress.


my issue it the motor, I have 2 options….option 1- i have a 4.7, its perky and reves hi RPM so would be good with turbos but at 100k miles a rebuild is in order. Im going to put little on the small side turbos for virtually no lag, maybe A/R 50 or a T1/T3 hybrid. ill study the compressor chart to decide for sure. im shooting for 700bHP and while not going balls daily I will haul ass if the mood hits, maybe a weekend drag for test tune etc. i want fast and show.


Option 2- LS3 or LSA swap, I know boooo but cant argue with hght hp potential and dependable motor. There even a schematic for wiring to keep stock gages working,


now to my point, you guys helped me with my fuel issue hopefully you have more incite on this.

My issue is while striving for 700BPH I cant find critical forged rotting assembly parts I need as well as cam, valves and springs for th 4.7 option. Does anyone have a line on a company that produces quality forged parts,


700bhp is an arbitrary number just something I picked. I welcome input.


Special system lower 5-7” in rear and 3”-5” in front have to see the look. Will have air shocks providing lift for steep drives stc.


Ive located a Mossler 8.8 rear end that’s been shortened 5” each side, allows me to run the 22x13” tires I want. Yes I need to tub and move some suspension over but worth it.

Anyone have a line on a durable rear end with 700 ftlbs torque for decent price?


Thanks julian

Holy poser...it's not really a clone if it has the looks but not the goods lol...think you hit the nail on the head with "queasy" lol. I do like the color though.

You will not find much for the 4.7 because aftermarket parts were virtually non-existent when it was still in production; good luck now that it's been out of production for a few years. Go here: http://airram.com and see what they have, those guys were always the reigning experts on the baby engine that couldn't. Hit them up, if there are any goodies to be had anywhere, they'll know where to find them. Give this a read as well: https://www.dodgetalk.com/forums/showthread.php?t=367696 (I just figured out you need to log in; if you're interested in adapting an Eaton blower to a 4.7, register for the site); might work out better than turbos, just a suggestion (this was done in a 2002).



LS swap = *** and you're a quitter. You'll not only have the SRT guys already making fun of you but the rest of us too lol.

Your arbitrary 700bhp number probably (and be probably I mean you'll detonate the engine first) isn't gonna happen with a 4.7; it was never designed to be a performance engine. A built hemi swap would be the hot ticket here, easy to get a harness made and find the parts to do it, lots of aftermarket support and you can build a 6.1 block to handle well over 1000hp.

Mossler or Moser? I assume it's Moser. Regardless, if you found a rear, why ask for another? Anyway, the Dana 60 out of a real SRT reg cab (if you're undersprung) might be what you're looking for, though you may need to narrow it.

Recommend you talk to Lethal Hemi with what you want to do out back; take a gander at his truck.

Traction. Stock OEM SRT RC springs have snubbers built in plus a wind up shock that attaches to the Dana. Some form of traction aid will be necessary (big power plus empty truck ass end = no weight over drive wheels). I'm partial to the Cal-tracs.

Now for the elephant in the room. Transmission. You haven't mentioned if you have a stock or auto. If stick, count your blessings and get a Viper truck T56 and a good clutch. If auto, well then...you're screwed unless you were intending to swap it out anyway. More than a few members have just because the stock RFE doesn't hold up when you start putting some actual power down (plus they suck up power too).

thanks for the info guy thats what i needed, real info not just articals in a glossy magazine. my issue is i dont know much about Mopar powertrain but want to. i said ls swap cause ive done a few twin turbo builds and they are very dependable. id rather stay true to the platform and use mopar, ill look into 6.1 if it can reliably hold 1000hp. and yes im screwed its a slushbox trans, the worst trans ive ever driven so ill have to fork out the cash for t56. oddly enough the trans from a 300zx turbo can hold 700hp and use to be a common cheap LS swap but this will be a daily driver so need dependable. thanks for info, keep it coming if you have comets

Give this a read, basically they stroked out a 6.1 to 426, put P&P Apache (392) heads on it, a fairly mild cam (for a race engine) with a carb and once dialed in delivered over 700hp naturally aspirated on pump gas with slightly less than 11:1 compression:

https://www.hotrod.com/articles/mopp-1304-can-you-hemi-now-part-2/

Imagine dropping the CR and boosting it lol.
You don't necessarily need to stick convert it (unless you want to), a built 518 or it's variants can be built to handle a ****load of power and still give you an OD gear.

 

[HemiLonestar]

This is what happens when the factory builds an aluminum 426 with a 3 liter blower on it...

i know mopar guys are die hard fans and the thought of a lsx in a ram makes u sick inside. i use to be a brand loyalist when i race motorcycles, but when u have a guy pull 10 links on you on the front straight away that loyalty starts to fade and you start looking at money vs hp. ill just have to do research into the hemi, so far ive read the only motor i believe can compete is the 6.2L and damn it must be made of gold as much as they cost. i want a fast truck but also need it to start every time and you cont contest the LS reliability. either way this cost a lot of money and if i end up using a LSX block guys might be laughing but they will do so while siting at staring line.
im not writing this to start at whos better thread, i thought this be the best place to get info from real dodge drivers

A 5.7 stroker motor will give you plenty of horsepower to put you out front of the pack. At that level you will need a built or swap transmission to hold the power. If you can't afford a hemi, then I say drop whatever you want in it that makes you smile. Just be prepared to be ridiculed.

 

[ST-8]

Dollar for dollar LS wins, for what your gonna spend to make 600hp out of a hemi you can prob make 1000 hp out of a LS. I love my truck but I would personally just buy a Chevrolet or GMC, starting with a better platform.

Hemis are expensive, but worth it. There’s a guy on Facebook and I’ve seen him on a few YouTube drag channels that took a 4.7 truck and LS swapped it, twin turbos, tubbed and caged, it runs low 8’s I believe, 1050 whp. But that is by now means cheap either. Hemis are finally at the point there is a lot more aftermarket support, tuning and knowledge, you just gotta be brave enough to go down the Mopar road. I don’t have any experience with the 4.7 motor or wiring, but I did a 392 Hemi stroker, 46re/A518 trans swap and I’m planning on doing a single turbo project later this year

With that being said, don’t let the dodge guys bully you. Horsepower is horsepower and should be fun for you. So whether you stick with what you know or challenge yourself with the new crazy Hemi world, make it fun.

What fun would it be if everyone did the same thing? If you want power and you have the money, do it any way you want.
