LOW BUCK, JUNKYARD DODGE MAGNUM 360 MODS PT 1 (WILL IT RUN?)

[@302hobronco]

I have 1998 1500 sport with the magnum 360. Bought it new in 98 with 60ish miles on it. Still running at 208k miles. Original engine and Trans. I've only had to replace a couple alternators, radiators, one water pump, 4 tune ups, and rebuilt the rear axle once and a muffler. It has been a very faithful truck.

The plate on the bottom of the beer keg manifold is notorious for blowing the gasket and creating a dead hole by sucking oil up into the intake and going into the intake ports making an oily looking plug. Easiest way to check is hold the butterflies open on the throttle body and shine a flashlight in. I've got many of the magnum engines that people thought need rebuilt that are perfectly fine. The new gasket kits have shorter bolts for the plate to stop this issue.

[@jeeptk]

The first sign of the lower plate leaking is the engine pings.

With the engine not running just open up the throttle body and look down and it look like an oil slick

[@konnerkramer329]

you can also put your hand over the oil fill hole with it running. it will have a ton of vacuum in the crankcase when those gaskets fail.

Pull the PCV out of the valve cover and check for vacuum. If it’s really bad it will have vacuum. Otherwise look down the t-body for oil laying on the bottom.

The stock intake looks like half a keg turned sideways. Have a good day

[@carportshenanigans5918]

I’ll be watching! Decent stock numbers, but not too surprising. As a Ford guy, I can say I dig those late model Magnum heads…if I remember correctly, I think they have 8mm valve stems and an exhaust valve in the neighborhood of 1.625”- probably why they sounded so good in trucks with a cat back exhaust. I’m curious to see if the longtube headers can bring peak power over 300. I helped a kid install longtubes on his ‘95 Ram, then I fab’ed up a full 2.5” true dual exhaust with Flowmaster Super-10 mufflers…that thing was L-O-U-D. I also milled, radiused, ported and polished his throttle body. The kid used to “goose” the throttle all the time to get it up on the converter and it would bark, I could hear him leave the shop and continue to hear him (from inside my apt!) all the way to his neighborhood! It was about a 5-6 mile trip and my apartment at the time was about a third of the way through his commute. We had planned to install a small cam with a tight LSA and take 2” of runner length from the intake but he ran out of cash and I got married and moved away. Such is life, I’d like to play with one of those again.

[@lukestrasser]

This was awesome! I hope someone will loan you the EFI M1 single plane intake, and a Dual Plane M1 Carb intake!!!

For some reason my 97 Dakota is very picky with injectors. I had a misfire on cylinder 2 and diagnosed it as an injector. I used 3 different aftermarket injectors from AutoZone and O'Reilly's and the misfire persisted. I was stumped for a while. Thought I might have misdiagnosed it and went through the steps again. Sure enough, I had it right the first time. I moved the brand-new aftermarket injector to another cylinder and the misfire followed. I measured the resistance of the aftermarket injector and compared it to a good OEM one from another cylinder and the aftermarket injector was at 14 or 15 ohms if I remember correctly and the OEM was 8 or 9 ohms so that was the problem. I finally broke down and paid the extra $60 dollars for an OEM Mopar injector and the problem went away.

As a magnum owner I can tell you that those Chrysler EV1 injectors that came on those engines are complete garbage and simply replacing them with anything EV6 or newer even if they are under rated for that engine will greatly improve things.
