    A body big block cam specs

    67 and 68 383’s are very different. 67 383 had closed chambered heads and a small CFM AFB with the narrow bolt pattern. A bodies had a one year only left manifold with the most restrictive dog leg. B and C bodies all had log manifolds on 383-4bbl 68 383 all had 906 heads with a 2806301...

    Usable power for the street?

    I think that 55hp increase is a smokescreen because it's without accessories, an air cleaner and with headers. That's the only way he got a 300hp crate motor to make 300 hp. And don't forget that a JY 5.9 with the same setup but with the beer barrel intake and EFI made within 1 hp of the crate...

    Stock 1989 318 w/ 48k Miles - Rebuild Recommendations

    Those Magnum manifolds should work in a truck, although you might need to be creative with the PS pump and brcket if it has that.

    422 dyno fail

    I’ve tested a few real duds over the years. But the ones that come to mind had some pretty notable deficiencies. Here’s one...... 396bbc. Oval port heads, Comp 280 Magnum cam, ex manifolds, Ede 750, and the big problem...... an SP2P intake. I don’t remember the tq, but it was low 280’s for hp...

    Engine & Transmission Compatibility

    A '90 is not a Magnum, it's a roller LA. It's neutral balance, so you may be able to make the flywheel work- I'm not 100% sure, but I recall the 273 having a smaller crank register (OD). You may be able to have your flywheel bored to the later diameter or find a later 273 flywheel to bolt up...

    Jeep exhaust Manifolds instead of headers, are these the large opening manifolds?

    Right I didn't word that great, more like 20-30 lb-ft across the board and 30hp PEAK gain. It seems to run out of breath somewhat around 5800 RPM. I have the shorty headers currently and not only are those mediocre at best themselves but I feel like the tiny 2 1/4" head pipes that snake super...

    Magnum Heads

    I am running those same manifolds on my MP R/T heads and I had to get some plates cut to run them. The material around the port on the head was too small to seal the port in the manifold. I've seen OEM Magnum heads where there wouldn't be an issue, but I've also seen one's with the same...

    magnum manifolds

    I have a set of manifolds off of a 2000 ram 5.9. The opening is 2in. The motor is a stock 2000 5.9 other then a carb conversion..... Reading on this site, dual 2.5 in. exhaust seems to be the recommended size. My question is, are most of you converting the 2in to 2.5in at the manifold? If so...

    I'm wanting to ditch my OLD low hanging headers, are these manifolds worth it?

    You could source a Magnum manifold off an early Jeep Grand Cherokee for the right side locally. If it has the big 2 1/8" outlet, they say it flows as well as a right HP manifold. And that is the hard to find (i.e. expensive) one too. Left side you need any HP manifold for an A-Body. The...

    5.9MAGNUM EXH MANIFOLDS

    On a 300hp crate 5.9l magnum, they did 318,360,340 manifolds and made 311hp, 314hp and 315hp respectively they didn't have magnum but there around 340 output. headers they had shorty, 1 5/8, 1 3/4, tti and made 321hp, 319hp, 319hp and 327hp respectively. other than the tti there's barely any...

    HP gain with multi angle valve/seat

    Redo the heads. Depends upon how far you go. 5 angle valve job with 70 degree bowl cut and bowls opened to about 88-90 percent of seat size, chambers unshrouded and last seat angle cut blended into them, and heads decked to raise compression, then 50 hp may not be out of the question. The...

    LOW BUCK, JUNKYARD DODGE MAGNUM 360 MODS PT 1 Richard Holdener

    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.

    My way of a mission impossible 318 budget :)

    ...from a 72 scamp , i bought another set of open chamber 318 heads and another 2bbl intake to rework them a bit , i have a couple of magnum manifolds laying around too , im planning to remove a bit of weight on the fury but not much , its huge but nkt that heavy , i really want a cruiser...

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

    You shouldn’t have any trouble with codes unless the heads have valve seating troubles. The stock magnum EGR feeds from the exhaust manifolds to an EGR valve in the kegger manifold via a stainless steel tube. The biggest issues I know of are first off finding a set of magnum heads available...

    408 Stroker in a Dart

    ...Rick Ehrenberg ran 340 manifolds on a rip-roaring Ray Barton-built stroker. Cost some power, sure, but it still ripped. I think that early (92-3) Dakota Magnum manifolds flow even better, though I have no idea how the packaging would or would not work on an A. (I know they can work on an...

    Ok fellas...318 help needed , Mpg , reliability and enough power ***for a big boat !!!

    I would pull the heads for no other reason than to get hardened exhaust seats installed and a valve job done. While they're off, I'd have 'em milled just enough to get 'em flat--not looking for a compression bump, just an excellent gasket surface. New valve seals and a set of fresh springs...

    Headers

    So I'm running 2004 dodge ram magnum 5.9 stock exhaust manifolds on my 360ci barracuda gasser and my steering column is hitting the left side on the rear of manifold and I was wondering if running headers will fix the issue or should I run a different set of manifolds. The manifolds I have are...

    Magnum vs LA block...differences...preferences

    The magnum blocks still use the out dated 2 piece rear main seal. The cylinder heads use flimsy rocker arm design, limited intake manifold selection, cylinder heads that are known for cracking. I don't know if this is true or not but I've heard that a 0.040" over bore is pretty much the limit on...

    340 Vs 360

    Very well put. I don't think anyone will argue that "stock" as factory delivered a 340 will out run a 360, all else being equal. It wasn't until 74 I think that there was a hi-po 360, a friend had a 74 Duster, 360 four barrel that ran decent for what it was. What the 340 guys (yes, I have one)...

    318 and 360 small block question

    From my experience in rebuilding both engines, a bunch depends on you, the car it’s in and what is expected from the engine/car combination. While you did state some practical and honest goals, I’ll take that description and run with it. For mileage considerations only, the 318 wins and will do...
