    Not a Degreed Engineer. But have held the title on occasion.

    Spent more time red-lining drawings and pointing out Degreed Engineers screw ups, to the point they should have been paying me for their Job and fired them.

    As stated EXPERIENCE Trumps everything!!

    I've trained Engineers because I have the Experience and all they had was the Degree.

    I'll hit you up when I am back up and running. Will be cool to see the swap.

    Actually come to think of it the Rest of the Aviation world Considers me a Licensed Engineer. But our good Ole USA doesn't.

    I'm a farm-boy with grease under my fingernails - and a degree from the shade tree school of hard knocks.

    I've worked with very many engineers that couldn't tell you what day it was or how to work a soda machine, jump start a car or even change a tire. I've also worked with some awesomely brilliant ones. Titles are titles and not much more.

    Really? Explain that to the EASA and JAA and CAA!!

    To work on aircraft under their Rules you have to be a Licensed Engineer with Type rating for the aircraft you want to work on.

    Which is the same as an FAA A&P Mechanic. Which yes I am!!

    Just saying ENGINEER doesn't mean a whole lot except a Title and maybe a Degree.

    I was an Instrumentation Engineer at one of my previous jobs.

    I'll elevate my status as high as need to make my paycheck FAT!!

    This project really whipped my ass, I'll tell you.

    SO if I drop a Hemi in the next one with the same ease, will that gain any respect? Because all I have seen for years is nonsense about how hard it is. Has anyone ever considered just cutting out the troublesome crossmember and starting over?
    I can see how reading comprehension is so hard for an engineer like yourself who only sees numbers. Where did I say that custom fabrication is "hard"? Does that custom fabrication work take time? or are you just that fucking good? Now, account for your time at the rate of $100 an hour like any other shop. Would you still like to argue that it's cheaper to build a 400hp/400tq, 16mpg Dakota by jumping to an LS swap?

    here. I'll detail my build for you.

    Mopar M1 2bbl intake $400 used
    Mopar mid-length headers, $200 used
    Hughes camshaft, springs, retainers $500 new
    SCT programmer with unlimited tunes $365
    modified stock TB opened up to 52mm $100
    Time to do a cam/intake swap 8 hours start to finish $800
    Time to install headers/exhaust 4 hours $400

    Hp output at the wheels 285hp/325 tq.

    MPGs 14 overall, but it's not a daily driver so when I do drive it, I'm beating the snot out of it. it'll do 17.5 on the highway, so probably an honest 15-16mpg overall.

    Total cost including $100 for an hour of time -- $2765. How much did I actually spend out of pocket? $1100. truck already had an M1 on it when I got it. Can you build your LS Dakota for $2765 including sourcing the engine and transmission, and accounting for the time of the custom fabrication work, and wireharness/electrical work?


    Now, I know that my rear wheel numbers are not what you were looking for, but Hughes charges the same for every cam regardless of the cam specs. For the same money, I could have had a cam that has a higher RPM range and makes your magic 400hp mark simply by moving the powerband higher into the RPM band. 325 rwtq is probably right at 400 ft lbs at the crank.

    Mopar Muscle took the 385 hp crate motor which is nothing more than a truck 5.9L Magnum with a carb intake, headers, and distributor, and a bigger cam, and they made 408 hp at the crank and something like 425 ft lbs of torque with stock heads, and stock long block!

    I have no beef about putting whatever engine you desire in your Dakota or anything else. That's the essence of Hot-Rodding, and I applaud these efforts. Just don't make an ass of yourself by spouting untruths about a platform that you simply don't understand as justification for those efforts. We get it, you like Chebbies, and they don't make a decent truck - so you put something you know into a Dakota. Great. Go drive it and enjoy it. That's what it's for isn't it? Because if it's supposed to be a sales tool to help you be the LS engine disciple - you are going about it all wrong.
    and that's where I think everyone's beef is coming from. not that you did the LS swap, but that you're trying to argue that it's faster, cheaper, easier to do an LS swap than it is to make power out of the worthless magnum engine.

    1) I wanted to see if LS engines might be a feasible alternative to the diesel hybrid magnum motors that I have.

    2) Reading posts and seeing people say "man its too hard", makes me, a former mechanical engineer, look for a solution.

    3) I had design goals of 400hp/400TQ, which would put this truck in line with newer vehicles, at a fraction of the cost. The increase to 16 MPG has not been too bad either.

    4) This particular truck would have been at LKQ being pulled apart, since no one wanted to bid on it.

    5) I wanted to use the experience as a way to gain knowledge about the LS engine, wiring, tuning etc. Primarily because I am starting a Factory Five GTM, which will use the same engine.



    6) Sorry, no. Not putting a Magnum in the GTM.

    7) Turns out, it was really pretty easy. Its turned out to be pretty nice truck. But as easy as it is to throw a turbo on, tune and make 750-800 hp is awfully tempting on this motor. Even though that was not my intention.

    8) Bottom line: 400 reliable HP with 87 ocatane and 16 mpg goal was achieved on day 1. SO now I am bored.
    doing the swap because you wanted to is one thing. doing it because you claim that the magnum platform is worthless and won't make good power is poor excuse. I did a custom build with a Chrysler 383 block stroked to 438, edelbrock aluminum heads, TKO-600, and made a streetable, reliable 505hp/535 tq. but the time and effort that went into that, I could have just done that with a Magnum block and a 4" crank kit. so why did I do it? because I had the 383 and I wanted to, not because I tried to tell everyone that the small block Magnum was worthless and couldn't be built.

    Now, will you please understand that you did NOT gain anything over that which has already been achieved by a Magnum motor setup. From your video where you show the Magnum motor on the floor of your shop, it is quite obvious you didnt do nearly as much research as you thought before deciding that the Magnum was not usable. If you would like to discuss specifics and maybe learn something from someone who has made their living as a machinist and building engines, as well as a lifelong Mopar guy, let me know. It was great that you set out to prove that an LS swap isnt too hard, now how about you take that same zeal and apply it to actually proving that you "cant make more than 300hp reliably out of a Magnum". There are multiple ways of doing it, just ask around on this board. You will not find a better resource on the internet than what you find right here...

    But tone the engineer arrogance down a bit, you arent going to impress anyone here with it. We may not have the book learning, but we have something even better. Experience.

    Danno
    Exactly! you did what you set out to do, and built something different and unique. that's cool, and earns respect. but your arrogance and attitude are what is earning you the shit storm being flung in your direction.

    I thought about mentioning that Engine.

    But that's like stabbing someone and twisting the handle for a Chevy Guy!!

    For those that even remember that engine.

    There has been so much done with the MOD Motor that many race sanction bodies have even gone as far as writing the class rules to eliminate them.

    Look at the after market support for the Mod Motor. Vast and wide as long as you don't need heads. Trick Flow finally released some heads about 2-3 years ago. Other than that most everything is stock offerings.

    Unless your willing to fork over the money for Mozez heads for your LS. It's just going to be another Chevy LS like all the rest.

    I've said it in the past and will say it once more. Anything that can be done with an LS can be done with a Mopar Small Block. Maybe not a Magnum Based only deal, as the Magnum Engine was never meant to be anything but a Truck Motor. But when you open up and look at all Mopar Small Block offerings, different story.

    Want to compare Oranges to Oranges: Compare an LS to a Gen3 Hemi.

    Comparing an LS to a Magnum is like comparing the Ls to a Gen1-3 Chevy. OUTDATED!


    Even though the pre-Gen-3 Hemi Small Block Mopar is outdated Technology. I have still had Chevy and Ford guys alike all but short of begging me to sell them my R3-W9RP combo to put in their Mustangs and Camaroes.
    1)Maybe not a Magnum Based only deal, as the Magnum Engine was never meant to be anything but a Truck Motor.

    I never compared them, I contrasted them. You chose to compare them.

    2)Comparing an LS to a Magnum is like comparing the Ls to a Gen1-3 Chevy. OUTDATED!

    Thank you. You prove my point exactly.

    Man you guys have been busy. OR not, I guess.

    Yup,

    But when you cant refute facts, you turn to the aforementioned monkey like behaviours....

    Facts are so DAMN annoying apparently. Funny stance for an engineer....

    Same here. My engine is around 400hp at the crank, still running with the factory pcm and SCT, and I have 4.56 gears. I got 17.2 mpg average on the last NATS trip, with the best tankful being over 19mpg.

    There you go. 400hp, 17 mpg, reliable daily driver that can make a 4700 mile trip in one week. Total money in my engine is about $4k.

    He can talk Shit on the 5.9 all he wants, but the problem is he is arguing inaccurate facts. He has his facts wrong but will not realize such.

    FWIW, once upon a time I made 592rwhp with a stock bottom end, including stock cam, mildly ported heads and 18psi, without a tune. Only went 11.3@120 with that setup on 15psi, but that was lifting on the topend cause it was going lean. With enough fuel and more stall that would have been a solid 10sec setup. The potential is there, just like with any engine out there, and boost definitely helps level the playing field.

    How far you from Belvoir?
    LOL Already did 9 miles today, running in the snow is great, definitely a good workout, kinda like running in the sand, but colder.
