I finally dug into my misfire on my 96 Ram 5.9 Magnum. As I suspected from leak down testing, I have a burnt exhaust valve on cyl 1. I got the drivers head off yesterday and can visually see. Going to do the intake plenum block off plate as well. Since I am going to be this deep in, considering a new cam. 93K miles and bottom end is in good shape. I use the truck a lot for towing camper and car trailer, so for me a towing cam would be good. I do have a SCT tune, but will keep the stock intake and heads (assuming they are not wasted). 3.92 gears. In talking with Comp and Hughes they are saying these cams. http://www.hughesengines.com/Index/...arch=0814&submit=Go&partid=30212and https://www.compcams.com/xtreme-ene...ulic-roller-cam-for-chrysler-magnum.htmlAnyone have feedback in towing use? Side question, on these engines, when the crank damper is at TDC, should the distributor rotor point exactly at the “Cylinder 1” marking on the plastic inner cover? Mine is slightly before and unsure if this is correct. I do note a tiny bit of timing chain play if I reverse it, but not that much.

Go to utawesomeperformance.com Marty knows Magnums. I have his UTP 500 cam in my LA 360 with stock magnum heads and this cam pulls really well. Send Marty an email an he'll get in touch with you. You would need a tune with this cam because of the 108 LSA but it's worth it. What I don't like about the Comp and especially the Hughes cam is they have too much lift. Stock magnum heads quit gaining air flow at about .450 lift, anything over that starts causing turbulence. The UTP cam gives you more duration than either of those cams and the tighter LSA improves the lower end torque.

Guitar, do you have any experience with the plenum plates Marty sells for the beer barrel intake?

I misspoke. Not plenum plates, I already have those. These things:

Got a reply from Marty and I guess based on my specs he is recommending a custom grind. “ I would suggest if you are using stock heads, stay with a 212/212 114 lsa. Keep the lift at 0.456 so you can use stock springs and rockers. If you decide to order that cam from me, I will send you the tune for free in unlimited and any octane you use.”

My engine is carbed with an air gap intake, 650 carb and long tube headers. So I don't have any experience with the plenum reducer plates. I was going to keep the engine injected and use the plenum reducer plates along with the oil shield but I didn't have a 5.9 short block, only a 5.2. My 360 LA was a reman .040 over block so I decided to keep it, put the magnum heads and front accessory drive on it and use a carb. I also used the Hughes valve springs, 1110? I think and their retainers. I originally used some 1.5 SBC roller rockers because the original plan was to use a solid roller cam, but later upgraded to stainless 1.65 rockers for SB Chevy. They work just fine since this isn't a race engine. I still want to put the solid roller in it but I think it's just too big with 246/246 duration at .050 even though with the 1.5 rocker it would only be .498 lift. I may still put the solid roller lifters on this hydro roller cam though as the Morel retrofit lifters have been nothing but trouble.

Sorry but those plenum reducing plates are worthless. There is no fuel to keep suspended so no issue there, they may help throttle response but those engines have no issues there either, they are very responsive, also with a smaller plenum volume the cylinders will have more effect on each other than when they have a larger volume especially those cylinders breathing from a corner, what are they supposed to do when the cylinder right befor it in the firing order just sucked all the air out of that corner right before it started trying to pull in air? The large plenum reduces that effect, so in my opinion they are a waste and actually counter productive. If you wish to increase the rpm you can cut down the runners some but again you would actually be increasing the plenum it pulls from witch is not a bad thing. A bigger plenun volume helps smooth out the flow through the throttle body making a small throttle body seem just little bigger. That big plenum is not hurting a thing. Maybe, but maybe not. I know Marty has tested them. Those engines do have good throttle response in stock form probably from the small camshaft and higher velocity ports. With a bigger cam and higher flowing ports they may indeed do some good. I know what a difference too much plenum volume can do to slow the velocity in a race engine. Might be one of the reasons Indy's mod man intakes don't work to well on some applications.
