Mancini Racing just told me that these things were out of production and no longer available...and honestly, the price seemed a bit ridiculous anyway. Can anyone share a source for these? https://www.manciniracing.com/maraenoilfib.html

I realize that I've got three questions running at once on this forum. One on FI, one on head swap and now this...but they are pretty distinct topics and searches didn't quite answer all of my questions. Personally, it looks like I'm going to have to save up for a while longer to do the heads...

This is what I have as a BOM for an aluminum head upgrade...I'm leaning toward the new Trickflow heads as I'm under the impression that the Edelbrock castings really need to be cleaned up before they can be used which adds time and wipes out the price difference... I have to be honest that I...

Which system did you use? How did it work out? Would you do it again? I was pretty psyched about the Edelbrock Pro Flow 4 but they're not available for our Magnums (LA small blocks only).

Just tossing this around in my head this morning...looking for your thoughts and opinions here. So I have to say it; I find the Magnum 5.9L to be pretty uninspiring in stock form. I'm not expecting a big block killer/hot rod motor or anything but it seems to be lacking a "spark" that makes an...

It’s always nice to see what our motors can do. The first one is in the nines on spray...

Have you guys experimented with ignition timing much? While I have gone through nearly every nut and bolt on my Dart in terms of body, suspension and drivetrain, I have never messed with anything on my Magnum 300 crate motor beyond bolting up the headers and changing the oil. It runs fine...

My thought at the time of buttoning up my Magnum swap was to keep it modest. The ~300hp motor just didn't warrant a loud exhaust and I liked the idea that at least with the hood closed, the car seemed totally stock. So I went with an inexpensive stock style muffler Well...that has since...

It sounds like they both perform well but looks like the Iron Rams will save $600 while the Edelbrock heads will save a bunch of weight.... What other pros/cons are significant here? Which do you prefer? Edelbrock Performer RPM Chrysler Magnum Cylinder Heads 61775 Hughes Engines

So it seems like a set of heads, cam/valve springs and the right intake can pretty easily get you into the 12s but how far can you go with this platform? From what I gather, the LA 360 has some advantages at the higher end over the 5.9 and I assume that the same applies to the 318/5.2. Have...

Heyah, guys. My winter project list includes new cam for the 5.9L "Magnum 300" and I could use some help in picking the right one. My goal is for a strong/broad power band as I'm building this car to be more well-rounded rather than a dedicated drag car. I have a 2600 RPM stall, will have...

Probably another noob question-- I have a probe for my water temp gauge and a switch for my electric fans. One should go in the manifold...what about the other? Does it matter? I'm not sure if it matters or not but the car is a Magnum 300 crate motor with LA style waterpump, etc. Mopar M2...

Well, I have been driving my Dart all over the place and the 5.9L Magnum 300 crate motor is running like dream. How high can you safely rev the stock rotating assembly? Where do the stock motors tend to reach their hp/torque peak? I have a 5700 RPM governor in the rebuilt 904 but I haven't...

Ok... I'm back with another novice question for the forum- Is it possible to install the stock transmission cooler lines while the engine and transmission are in the car...or am I just some kind of idiot...or both? :D Because there is a sharp bend at the end that connects to the radiator...

I'm getting close to firing up my Dart with the swapped motor (March deadline) and I'm going to change the oil before turning the key. It occurs to me that this is a different motor and I shouldn't take anything for granted... Which oil types do the Magnum motors like? What weight? Do you...

So far, everything looks like it should match up but I read somewhere that the Magnum motors may use a different water pump that requires a different RPM in order to flow enough coolant. If this is true, does it also apply to the "crate engine" version? Externally, the water pump looks the...

It looks like there are some opportunities with the Magnum 5.9L with head and cam swaps... but how far can you go if leaving the stock bottom end in tact? What are the best options for FI? Do they typically handle nitrous well?
