    Damn good info

    Magnums are the ****, 9 to 1 compression better heads bigger valves better stock camshafts 1.6 rocker ratio, roller camshaft, no exhaust manifold stud coolant leaks. We put a stock magnum 5.2 in my brothers plymouth just swapped on a intake carb and manifolds, hauls ***. Also delivers decent...

    70 Dart S6 to 383BB conversion - Cast Iron Manifolds

    Yes HP manifolds. I believe the driver's side is 2843992-2 which would be 68-69 B body 440 magnum and 68-69 383 magnum.

    Backfire on deceleration?

    usually, if you have open headers or manifolds it will pop out of the exhaust after running at a constant rpm; say 4000 after a little bit. I have a '73 318 in my duster with a carb. However, these pops are pretty small and wouldn't blow out a muffler like that...

    Cheaper than dirt 318 build

    some of what you're saying here is running completely contrary to "cheaper than dirt" build. first, i'd get that motor running and establish a baseline. compression, cylinder balance, leak down tests. check the plugs while they're all out. visual inspections on everything-- gaskets, seals...

    [FOR SALE] Stock 318 engine manifolds

    I just tried to PM you & got the same "error" message after 3 attempts. I would like to sell all three manifolds at once but make me an offer on the exhaust manifolds, as long as it's not a ridiculously low offer. I also have 2 exhaust manifolds from a 95 Magnum V8. PS, It says your in box is...

    Cheaper than dirt 318 build

    Your right I was getting ahead of myself, thank you. I know a guy who knows a guy sorta thing as far as the machine shop, and I'd get it dome cheap. How hard is it to swapp a 318 magnum compared to that 85 318. Is it as cheap and just as simple compared to it with the added bonus of power...

    5.9MAGNUM EXH MANIFOLDS

    ...the steering tube. Mine was a manual steering car with a floor shifter. Very costly thing to do with the price of 340 manifolds these days. I was going to replicate that car with the exception of using a 360 and magnum manifolds on the swiss-cheese Valiant :p I wound up giving to RustyRatRod.

    273 Rocker on 340

    Which cam? IMO; running just 160 psi with the alloy heads, would be a gross unfairness to them, as would running less lift than at least what the Edelbrock springs are capable of. As to the 718001 cam; Installed with an Ica of 68* the V/P ratio is predicted to be 126, about the same as a 5.2...

    Best Top 10 Bolt Ons For a 318

    ...and you probably have to replace or repair these items anyways is as follows: 1. exhaust. 340 hp manifolds or more affordable 360 magnum manifolds, 2.5" dual exhaust, good sounding muffler and depending on your budget H, X pipe . As a near stock 318 $150 each mufflers aren't necessary nor...

    Budget cylinder heads for a 318

    there are solutions. there used to be a drill jig floating around, to drill a set of Magnum heads for an LA intake. If you buy EQ heads you (used to be able to, anyway) get them in either configuration, depending on which intake you were wanting to use. "318A" or 318 B" The 1st set I bought...

    Magnum head swap in factory ECU 2003 5.9 engine? Any Codes/EGR?

    exactly what I needed to know. thank you. I didn't want to over-complicate my original question. I have a line on a 2003 5.9 Dakota with a cracked head, into the water jacket. I also have a set of edelbrock magnum heads. I also live in an E-check county. So, I really have no plans of hot...

    273 Exh Port MisMatch

    And whatever you do, don't try to grind the extended port flange on #7 to get clearance, there's a water jacket right under the surface. I trashed a perfectly good 308 head that way. The only safe way I've found to do it is to mount a bare header flange as a spacer between the manifold and the...

    Junkyard 5.9 for my 72 Van

    You will need an intake that will bolt onto the magnum heads, straight down vertical holes. Can use your distributor. Your exhaust manifolds should bolt up as well. Professional Products 55026 Professional Products CrossWind Intake Manifolds | Summit Racing

    5.9MAGNUM EXH MANIFOLDS

    There's not a big difference in power its up to you. Manifold and header shoot out, magnum are similar to 340 manifold performance, there another shoot out somewhere shows the best pair is one 340 and one magnum, forget which ones. Installing Exhaust Headers Into 300hp Crate Engine - Mopar...

    1964-66 A body Gen 3 motor mounts

    Gen3 Mounts have never been available for the first of Abodies. I have just built a set of mounts for my 62 lancer 6.4 swap. After making a cardboard model, and actually bolting them in place. I was able to cut the pieces from 3/16 plate and weld them together. I used rubber mount insolators...

    5.9 magnum cam in a LA318(roller)

    ...I'd stick with the factory cam. Doesn't sound as fun or cool, but it may be your best choice. I like the eddy streetmaster for your purpose, along with the magnum manifolds. To add more, I'd suggest curving the distributor and put in some initial timing to help part throttle response.

    360 Magnum Build

    A LOT OF MISSINFORMATION HERE..... HERES RIGHT OFF THE TRICK FLOW WEBSITE. NO YOU DONT NEED TO MESS WITH THE MAGNUM OILING. YOU CAN STILL USE LA STYLE INTAKE AND VALVECOVERS. JUST NEED TO USE HARLAND SHARP ROCKERS. Magnum engines must use Harland Sharp S72025K (1.5 ratio) or S72026K (1.6...

    1998 360 Magnum or 1965 273 cu in

    Id keep the 273. You can perk them up but won't have the tire shredding torque of the 360. Your wheel arches are pretty narrow for any tire back there and the 273 with its manifolds sits nice in there. You can go magnum exhaust on the 360 and clear most everything under there but you still have...

    1964-66 A body Gen 3 motor mounts

    Been reading a lot but still can't come up with a solution for motor mounts. Is everyone making their own mounts.? Seems from older threads some outfit used to make them but no longer does. I'm building a 66 barracuda using a 2007 5.7 with a Ford T56 Magnum on 17" magnum 500s. Using SRT 300C...

    Stock 360 Upgrades for Crusher Cuda?

    If you have 360 exhaust manfolds You may want to consider just porting them as well or find some cheap truck or magnum manifolds since you’re already planning on grinding out the heads anyway. It would save you a chunk of money, not to mention the hassle and frustration of installing headers in...

    MPG build 360

    I ran a stock ‘79 - 360 in a heavy-ish B body, specifically a ‘79 Magnum w/a 904 & 2.76 gears on 235/60/15’s. Stock camshaft. Then I added a OEM iron 4bbl. intake and a 600 AFB, ignition was a MSD, junk yard distributor, dual exhaust @ 2-1/4 off of the stock manifolds, the air cleaner was a ‘72...

    B & C body 360 manifolds

    ...Spitfire headers on my '66 race car and they fit great, but, there again, manual steering. I never got around to trying the later Magnum manifolds. Some models are supposed to work good, but, someone else with first hand experience will have to comment on them. I guess to answer your...

    Magnum dyno videos

    The Base is the 300hp crate engine which is a stock 5.9l Magnum with a 4bbl intake M1 dual plane and 750 holley and headers. Seems about right with his 288 hp with beer barrel and manifolds. 300hp with headers imagine 4bbl intake for another 10-20 hp. (The mod is eddy heads air gap and a Comp...
