Thread: 360 magnum carb conversion?

  1. #1

    Default 360 magnum carb conversion?

    Is there any way to run a 5.9 converted to carburated and coincide with the 46re transmission? I know im gonna get a lot of comments to stay fuel injected but its just something im curious about. Seen some article recently that they ran a RPM airgap and a carb and gained over 40hp i believe?

    Just read a article they changed out the heads and cam with full length headers and dynoed about 430hp at the crank on the 300hp 360 crate motor. I haven't seen any fuel injected magnums make that much horsepower with those few modifications. I am just a cheap ass and want cheap hp without blowing it up with nitrous

    Just do a manual valve body on the 46RE...The less the PCM controls the better.

    Id prefer the manual valve body. So thats all i have to do to swap to carburated? My dad is old school and we could easily rebuild this in his garage. Id love the carb setup and remove all heat/ac and interior crap. Kinda like your rig just wanna have it more streetable

    Okay I'll bite , why would you wanna put a carb on it and have to be playing with jet's, power valves and setting floats, setting timing.. blah blah blah..I wouldn't wanna go there if it's a driver. If it's track only or a Sunday toy maybe?...NAH not going there!
    As for the Air gap dual plane, edelbrock has a dual plane and if you wanna save about $500 ebay a "proform Air Gap dual plane for $150.00 fits FI and carb small block with some massaging to get it to work I put one on my Ramcharger it works on LA and Mag motor's. or buy a carb air gap and have FI bung's added?
    Nx isn't your only option to make Hp on this motor, Cheapest yes, only no!
    Blower's work well with the right tune on stock long block just can't blow the heads off with 13lbs of boost (stock) if you want it to last .
    Or a Turbo Im making 310 @ wheels on stock long block with simple bolt on's.
    Heads and cam with same bolt on's should net you close to that power level with the right combo of parts what # are you looking for ET wise? or do you wanna bench race with the local cruz crowd? Come's down to where ya wanna go? How fast? and what do you wanna spend ? Hell for 20k you can run 9's and for 9k you can run 10's LOL j/k

    Mine was streetable, still would be if I didn't live on a dirt road, with the mufflers dumped it's a dust storm, looks like I'm going 50 when I'm going 10.

    If you want a fast street truck, do the 727 swap, 3.55 gears etc...46RE is power hog. IF you're dad is a carb guy who you can learn from do it...EFI is pain once you start modding what it is incontrolling unless you have a standalone.

    What I've noticed is carb guys are all about helping a brother out.

    EFI guys are too....For a fee, it's all about overhead...Screw Driver vs Laptop.

    well chas the thing is my dad knows all about carburated cars with no electronics. I added up the parts list to make that 440hp at the crank 360 for about 4000 bucks. I never seen a n/a fuel injected 360 make that much hp for 4000 is all im looking at is the dollar and cents. If i ever did this it would be a once a week driven ride. Just dreaming over here. Im all for turbos but my dad is not. Stubborn i tell ya. I just can get him to build it up labor free so ill go n/a

    Well said Dave , But in today's world carb guy's are slowly fading away and more and more "Laptop's" are taking their place on the track scene. I see alot more laptop's at our local tracks these days then screw driver's in the lane's and pit's...

    True that. And my redneck dad cant do a damn thing with a computer. give him a screwdriver and he will tune any carburated car. It took him years to get his 540 in his El camino tuned just right. 950 crank horsepower compared to the older 468 he had in there around 500hp scares the shit out of me

    Tell him turbo's where on P-52's back in WWII I was not a big fan of a hairdyer at first either but I also was a kid in the 80's when T-Type's and GN's went 11's with little upgrade's and on the street they ruled the Philly scene every weekend on 61st street and Delaware ave so I had an open mind.

    I had everything to go to a carb...Even rewired my truck for the anticiaption of ditching the PCM...

    Then I snagged a FAST XFI for cheap and sold all the carb stuff.

    In the meantime Chris nailed my WOT AF first time, I just have an idle issue. If I can get this thing running right with the stock PCM I'm selling the FAST. I just want a stout brakcet motor, I'll never be the fastest, but I can be the most consistant.

    Yeah i have it just stuck in my head to go carburated. I remember being a young child and my dad had a yellow 57 chevy 2 door nicknamed "dad and daves race car" By the way my name is Dave as well And ever since then ive had the love for american muscle. My dad is more of a chevy guy but had his share of mopars. He has had the el for 15 years did a entire frame up resto. and re did it a few years back. One day i will get pics on here even tho its a chevy

    Chris @ PIE? It isn't simple to tune with SCT but it can be done. I wanna see a consistant street drive FAST(or any) set up all I hear is talk and no walk around here

    Not many people do. But i dont want to do anything to the truck until i have the funding saved up. dyno and drag the truck stock then go back new driveline and slicks. No offense to anyone reading but I dont feel like adding a mod here a mod there. I want a transformation lol

    I wasted over 500 dollars on a AEM intake and a Mopar PCM. I couldn't tell a difference at all. Only in my wallet because of premium and 5200rpm shift point didnt do shit but suck down more gas. A fuckin dog after 4k IMO

    FWIW, a basic heads/ cam/ bolt-on combo on your 360 will give you about 300 rwhp. I think Robs Lil Orange Furor is making around 330 rwhp. Considering the drivetrain loss through the heavy 46re, truck 9 1/4 rear, and wheels made out of Mallory metal, that normally means 400- 475 at the crank.

    These magnums make power much easier than the old LA engines, but a 4400 lb truck with 28" tires won't run the same as a 3500 lb A body.

    Figure 2k for heads, cam, rockers, pushrods, etc. Another 1k for a 4bbl M1, F&B, and SCT, and 1k for exhaust. $4000 for 450 crank HP is not hard, I only have about $3500 in my combo, it made 290 rwhp with a small smog friendly cam. Since then, I ditched the mechanical fan and the cats, I might be near 300 now, and I left 20-30 HP on the table with the small cam.

    Drops panties faster than any R/T

    How much drivetrain loss is expected?
