    Choosing cam for 5.9 magnum

    I am not sold on reground cams unless you absolutely are having a hard time finding a new one for an odd application. My buddy just got the 5.9 in his 01 ram sorted out after a Hughes regrind failed. It flaked out bad on the ramps and base circle where the material was mostly removed, the lobes...

    Crosswind vs. RPM Intake

    Exactly what I was thinking when I did buy one. It also has an extra coolant hole for a sender/sensor at the rear of the intake which was nice for running a mechanical temp guage along with the factory sender as well. Came with plugs for the holes, seemed decent for the money, fit well. The...

    Crosswind vs. RPM Intake

    I agree, even though I did purchase a crosswinds for one of my engines due to the dual bolt pattern for a magnum swap, didn't want to go with the magnum air gap because of the funky thermostat/bypass location, as I was using the mag heads on an la. I have an rpm air gap sitting on my shelf for...

    Crosswind vs. RPM Intake

    Yes it is smaller. Forgot my measurements though. My 360 had mag heads and had great low and midrang was not built for rpm, so not sure what it would take to bottleneck your combo.

    Mopar purple .520" cam?

    Pulled a camshaft out of my dart's old 318 and was suprised to measure the lobes all were .345-.346" I have no idea how old or long the engine was put together. The previous owner had no info for me. I cannot seem to find much on it, I will check it with a degree wheel eventually, just wondering...

    What valve springs should I use?

    . No regrets at all for my situation, made it affordable. BUT, if I were not building a better engine for it down the road, I would have put better pistons in it. This 360 really performs well on the street, not sure if it would like low octane, never tried, I put a small enough amount of...

    What valve springs should I use?

    Timing is steady with the timing light, that timing tape really makes it easier to see what you have going on. Currently has 15 initial 33 total and starts, idles and goes wot well. I will have to report back after taking a bit more timing out of the vacuum canister, as my distributor I started...

    What valve springs should I use?

    The pistons are stock 1973 360. Head gaskets are blue felpro #8553pt. I measured .048" on a used set I have. As far as wide open throttle goes, it is hard to describe, it seemed to not want to rev as high with 35 btdc, I could try to advance my total again and find a way to better describe it...

    What valve springs should I use?

    I tried both ported and manifold vacuum. At first if I hooked up to manifold, it would stumble at idle. And if I hooked it to ported(passenger side of the edelbrock carb) it would stumble when throttle was applied off idle. I used a piston stop to verify true top dead center and applied timing...

    How it looks in the car, already getting dirty from the dusty harvest air.

    What valve springs should I use?

    Update on this engine. It rocks! Does not seem to like more than 33 degees btdc total timing. Tried vacuum advance, hates it, I even welded a washer on my vacuum advance pod to limit travel, still no likey. I put 2 factory light springs in a distributor that I welded the slots to limit...

    What valve springs should I use?

    Had to set the intake and valve covers on to see how it looks even though I need to install the valvetrain and pre-lube it. Pretty excited, I will need to burn off the 10 year old BFG's and get fresh rubber when it gets in.

    What valve springs should I use?

    Good to hear you are getting good service out of your springs. My buddy has a 01 Ram 5.9 he put the Hughes air gap fi intake on and a towing regrind cam in, along with this same spring-retainer-lock kit and a tuner. His truck has far more power but he plans on headers and a modified throttle...

    What valve springs should I use?

    Opened up the pushrod pinch, blended the bowls, got rid of some casting flash in 2 exhaust ports, smoothed out exhaust port roof, lapped the valves, gave it a wash and fresh paint. Ready for my springs to show up tomorrow. My second budget(ish) build 360 is coming along. I did install a swap...

    What valve springs should I use?

    I would have loved to go this route, but unfortunatly these springs have an outside diameter of 1.494" and both sets of mag heads I have measure 1.440" on the valve seat, I have a new set of Sealed power 340 replacement springs that I tried only to find they did not fit, measured them at 1.5"...

    What valve springs should I use?

    Dang, I wish I would have known about magnummopar before I ordered from Hughes today. As for my cam, it is a Summit 50052 with .454" when used with 1.5 rockers. So it should be around .484" with the magnum heads.

    What valve springs should I use?

    Yes, I checked them while ejoying a Hamm's beer after work. :). In all seriousness, the heads were free, I got 2 free sets for helping clean out a guy's old shop. I did not see any visible cracks or any signs of coolant leaking, just typical carbon.

    What valve springs should I use?

    I went with the 1110 springs and matching retainers/locks from Hughes. Looking foreward to putting this engine in the Dart to test it out:) Thanks for the replies.

    Brainstorming ideas for coolant crossover on Air-Gap intakes

    One thing to remember is even with the Magnum heads, you will have more heat to the plenum on an rpm intake just from the oil splashing on the bottom of the runners even without the crossover. Just not sure what non air gap intakes are available for Magnums. If you can put a tube of some...

    Drill mark on crank journal? Roller 360

    I did find a Magnum engine today with the oiling for LA heads machined in the block. Thought I would share as I was beginning to think it was a unicorn. A 94 casting date 360.

    318 rebuild

    What is nice is you have a roller cam engine to start out with. I would start with exhaust, a crossover of some kind like and H or X pipe is a nice place to start that will give you room to grow later if you go 2.5" or even a little bigger.

    Drill mark on crank journal? Roller 360

    That cam does sound good to a big car. I might get ambition to cam it over winter. Too many other projects going on as well. It is crazy how the prices on the Cordobas/chargers, Magnums, and Miradas have shot up in price in the last ten years, my 76 seems to look better every year, or maybe...

    What valve springs should I use?

    I have a 1973 model year 360 short block out of a camper with 80k miles on it that I put a Summit 50052 cam in. I am using the heads on another engine and got ahold of some magnum heads off of a 98 318 that I would like to use on this 360. The new lifters have holes for pushrod oiling and I know...

    Drill mark on crank journal? Roller 360

    So this engine runs fantastic! Now that I know it is good I regret not putting a cam in it. Pulls to 4500 and slows down around 5k, thanks to the stock truck cam w/.410 lift. Took the wife out for supper, over an hour long trip and it was a pleasure in our Chrysler. LD4B intake(that had bad core...

    Intake Manifold Question

    I blocked off the heat cross over in my Chrysler with an ld4b intake and 1405 eddy carb. Works great and less heat issues in summer. My Dart has an rpm air gap and 1406, works perfect without the heat cross over. I have cut a small piece of steel to shape and hi temp siliconed it in the hole of...

    Remove #5 and #7 plugs?

    You can either buy a short 3/4" wrench or cut a cheap wrench down to clear. The pics I posted were under the hood of my Chrysler, so I was kinda cheating. But I use this method on my Dart as well.
