I have a Magnum-based stroker and I will be replacing the oil pump in the coming weeks. I have a engine hoist on hand and two engine swaps for this car under my belt but none since the 4spd conversion (not sure if this is better or worse)... but frankly, I'm just trying to figure out if I can...

My engine is running great and pulling hard but it makes some noises that I don't like so I would appreciate any input on this. I have about 1500 miles on my Blueprint engines 408 stroker. This is a hydraulic/roller engine, Magnum block with Edelbrock aluminum heads and 10:1 compression. It...

Who is running an oil cooler? How did you decide on the size/dimensions/number of rows? Did you mount it to the radiator or somewhere else? Did you ever have leaks or pressure loss issues? Thanks!

The Dart stranded me last night for the first time since 1999 or so when I had a ballast resistor go bad and didn't know enough to have a spare one in the glovebox. My best guess is that this is once again related to the ignition but for very different reasons...I am sure I'll be able to...

Hey guys. I'm hoping someone has a pic on hand and wouldn't mind sharing. I'm sorting out two things and reference pics are a bit hard to come by so far. First, the bolt for the spring anchor bracket for the throttle return/kickdown linkage springs seems way too close to the carburetor. I...

Edit- never mind. I found what I was looking for.

Before my new engine goes in, I am seizing the opportunity to replace the rubber inserts in my motor mounts with urethane pieces. I am working on the '73+ 340/360 style motor mounts that connect the engine block to the K member. It seemed like a very straight forward job and I didn't...

If you were to consider buying a used engine sitting on a pallet, what would you want to see before buying it? I will be selling my Magnum 300 crate engine in the very near future. It runs absolutely great…but no potential buyer can (nor should) just take my word for it obviously...

Currently I have a good running, low mileage Magnum 300 crate motor that is plenty strong but not exactly thrilling in its current state. It certainly feels like all of the advertised 300 horsies are present but that doesn’t go as far as it used to. I’m tossing around the idea of selling this...

Just tossing this one around this morning...and input, opinions, experiences are very welcome. So I think most of us are familiar with the 4" crank stroker build for these motors and it seems like a very easy way to make a 450+hp small block. The downside to a stroker motor is that the longer...

I'm a novice when it comes to tuning so I could use some perspective and advice here. So far, I have ~750 miles on the Magnum 300 that I bought used from a good guy here on the forums. The motor is tight, doesn't burn oil, good oil pressure, no leaks...idles great too. Performance isn't...

Hey, guys. I have always done basic maintenance on my cars, occasionally getting a bit deeper but generally the tasks that I've done were without guesswork. For example, I'm happy to replace brakes, drop the transmission to swap out torque converter, etc. If I know how things are supposed to...

Ok...here's another Magnum swap question...when using the original brackets from the 318, the power steering pulley is off by almost a centimeter from the crank pulley when mounted up with the new Magnum motor. I'm not sure where the difference in spacing is coming from...but is there a...

How critical are these pieces? They connect between the transmission housing and the side of the block...

Stock "Magnum 300" with dual plane Mopar intake manifold, Demon 650, Doug's headers...looking at heads/cam next year. I'm having a custom system with an H-pipe being bent up now...What diameter exhaust system would be best for street (and occasional strip) use? I assume that "bigger is...

I'm back to concentrating on my Magnum swap and sill in the ever-lasting phase of buttoning everything down before hooking up the battery and turning the key. :cheers: I am reusing the stock manifolds from my 318 and I'm lacking some confidence in the original hardware... Can anyone...

Driver side exhaust manifold for my 318 seems to lacking sufficient clearance to attach to my 5.9 Magnum. As far as I knew, there should be no geometric difference between the magnum and the LA motor...do I need to pull the steering column? Or do I just suck? Thanks for any words of...

...and how do you like it? Was it worth the expense/effort? How did you build it to handle the stress? Does it sound good?

I have to confess- I know nothing about this motor! I recently heard a Grand Cherokee with a 4.7 drive past that sounded pretty healthy...though it may have been just a good exhaust system. Does anyone run one of these motors in an A-Body? Are they any good? Are there any advantages...

What is a good source for engine hardware? Nuts/bolts/washers, etc? If you have the original bolt in your hand and you're looking to buy a new one, you can measure the length, thread pitch, identify the bolt's grade from the marks on the head, etc... but is there a source that can help...

After many delays due to personal and business reasons as well as some competing financial obligations, I'm FINALLY ready to actually put the Magnum into the Dart. The transmission is bolted up but the exhaust manifolds and accessories are going to be installed after the motor is in the...

Forging ahead with my Magnum swap after a delay... :blob: According to www.Magnumswap.com, they suggest a mini starter due to clearance issues with the exhaust. Does this only apply to headers? I'm running the stock manifolds off of my 318 at least for now... Any other reason I...

So my 904 is ready to be picked up and installed on my Magnum crate engine. The engine came with the flex plate but It just occurred to me that it might not be compatible with my 904 and that this might be a problem since I believe I heard that the 904/magnum flex plate is no longer available...

Just want to make sure I'm getting the right stuff. Which spool mounts do I need for mounting a Magnum into the old 'Sport? I gather that the LA and Magnum use different mounts. Thanks for any suggestions! -Mike

I just struck a deal with another FABO member for a nice lightly used Magnum 300 crate engine that will replace my old 318. Until I can wrangle up some more cash, I am hoping to run my stock 318 manifolds. What do you think? will I be able o get away with these for a while? Will they...

This motor is sitting in a '73 D100...supposedly running, supposedly a 360 (though I would verify both facts before buying)...Holley carb (unidentified...does anyone recognize it?) rusty Headers, ugly green paint. They want $580...may include starter, etc...would you chance a modded motor...

You guys may have seen this already but it was a big help to me so I thought I would share with the group. A big thanks to the guys (or guy?) at this web site for putting this together.... it's a more complete list than the previous link I had seen. www.mopar1.us/casting.html

Based on previous advice, I'm having my 904 built and I have a prospect for a 8.25" axle...my goal is a reliable 12.9 car... This forum has been a great help so far...but since I'm getting a bit more specific/realistic with my goals so opinions would be very welcome. So how would you pick a...

I suspect it's the starter...but I'm not sure where to begin. This engine with 140k has sat for many years and is destined to be pulled in favor of a 340 or 360 (and possibly rebuilt) but I'd like to get it running again so I can at least move the car around if not drive it short distances in...

Hey, guys! some quick background- I have bounced on and off this forum for a few years now...not being sure what I wanted to do with my '73 Dart sport. The car was my pride and joy when I was 18 (back in the 90's) and I was never able to let it go, even after it was parked as I moved on to...
