You can get replacements from Mancini and various other suppliers. To remove the broken part, since you have the engine out already and the pan off, use a long flat ended punch to push out the broken piece. You may have to improvise a punch long enough to get into the hole since not all of the...

Cam gear will pull it up and should give you the correct end play. The magnum "stock" cam does not have the snout for the fuel pump lobe, thats the reason its shorter. If you are going to use the magnum front cover check it first as some of them will not clear a long snout cam.

Try http://www.kevko.net/mopar.htm Their oil pans are baffled and have crank scrapers built in.

Should be a bolt in swap except for maybe the electronic ignition. The 273 and 318 are both internal balance so no special flex-plate needed. If need be you can use the flex plate from the 273 on the 318 if the bolt holes in the 318 plate don't match. Hardest part of that swap is going to be the...

I have seen seal failures that were "immediate" where a piece of metal shaving got into the seal and ripped it but only once in my 63 years. Usually when a rear seal goes it does so gradually as the material wears out or is compacted by crankshaft wobble due to a bad rear main bearing. For a...

I know its going to be hard but make sure its not coming from the rear of the intake or the soft plug at the end of the camshaft, or, less likely, one of the oil gallery plugs. 6k on an engine isn't much and for the rear main to suddenly begin leaking that much doesn't sound logical. I'd look at...

I've seen 145 in my Dart for a short period. 408 stroker with an A518 OD tranny and 3.23 gears, 27" tall tires. Still had plenty to go but I was running out of empty interstate....

Oil pressure sounds ok to me. The groan/moan could be power steering pump, alternator bearings, water pump, or maybe even the front pump in the tranny. My 98 durango moans when I first start it if I leave it in park because the tranny doesn't pump in park. If I start it in neutral no moan.

Look at the Crosswinds brand of intake. They are relatively cheap, have dual bolt pattern for both LA and magnum heads and have the bosses there for the injectors. Then al you need is for the bosses to be drilled for the injectors. No need to weld in bungs. I know that Crosswind is a chinese...

On mine was easy since I am using EFI and the shaft is fixed. With a normal dist I imagine you could pull the plate out of it and wedge the mechanical advance and then see if the shaft moved.

Pull the dist cap off and move the rotor back and forth and see how much play you have. I had a problem on my magnum 408 stroker where the slot in the intermediate shaft was too large and sloppy, allowing the dist end to move around. A new intermediate shaft cured the problem.

Usually the cam card gives a generic spiel on how to do it. There is a book named "How to build big inch small nlock MOPARs" that has a whole chapter on how to degree a cam. Well worth the $20 or so just for that.

Should have gotten a cam card with the cam. Degree it according to the specs and it should work fine. Can't depend on the old align the marks stuff with an after market cam.

Did you time it with the vacuum advance line off and plugged? Is the vacuum advance line on a ported port (above throttle plates) as it should be?

I like the kevco because it doesn't have any clearance issues with the k-member, tucks up nicely so it doesn't drag, has a built in crank scraper and trap door baffles so your oil stays where it belongs. You will need one of the LA main bearing bolts with the stud for the windage tray to mount...

This is what I am using. Would not go back to any other brand... http://www.kevkoracing.com/

Don't think so but if you have the rods from a magnum the whole set will work.

Nope, it doesn't. But I thought thats what electric pumps were for.....

You can use the pullies from an early 90s Magnum engine but in order to drive the water pump it needs to be reverse rotation so in addition you will need a magnum front cover.

Yep, those will work. You will need the dogbones and spider to hold everything in place though. Because the roller rides over the cam lobe differently you can get a cam with a steeper ramp and longer open time allowing more cylinder fill. So any cam designed for a flat tappet cam is hard to...

If you can get a 94-96 Ram, B series van, or (if you are lucky) a Dakota R/T with the 5.9 and A-518 OD tranny COMPLETE then the swap isn't too hard. Lots of wiring to interface between the EFI and the old dart harness. You will need to have an electric fuel pump that will put out at least 40...

All of the 92 and up trucks use the bosses located in the side of the block about halfway back. When the Magnum 5.2 first came out it was basically the roller LA block from the late 80s and the castings still had the front bosses like the LA. For some unknown reason MOPAR did away with the...

If you want to go with a 5.2 (318) look for a pre-95 model because I think 95 was the year that the motor mount bosses disappeared on them. The 5.9 had them up until end of production in 2003. Tranny depends on your skills as a fabricator and willingness to cut up the floor of your car. The...

That gasket will work without any mods on a MAGNUM PAN, not an LA. Problem is the magnum pan is different at the front ends where it goes around the front cover. The LA pan has a notch at the end of the rail where the wrap starts around the front cover. THe magnum pan DOES NOT so if you use the...

No one makes a center sump for the magnum (without the notches in the front ends) but you can use the LA pan and the magnum one piece gasket. Get the front end seal from an LA pan gasket set then at the top ends cut the notches off and fit then and use RTV to keep them in place while you put the...

Don't think anyone makes a one piece pan gasket for an LA but the one piece from the magnum 5.2 will work with a mod. The LA oil pan has notches on the front end where the pan rail meets the part that goes around the bottom of the front cover. The magnum does not so naturally the 1 piece magnum...

If you got the flywheel with it then pull it off and look at the back side. You will see where metal has been removed to properly weight the flywheel for external balance. You should be able to tell by looking at the front damper on it and see the same thing unless someone has put an aftermarket...

You can use the 273 forged crank and depending on what pistons you choose may be real close on baslance. Ther is plenty of area on the counter weights to add mallory metal to balance if needed. Just be sure that you choose a good machine shop. As for using a 360 crank, I did that years ago but...

Is it oil or tranny fluid? You said that you ran it and didn't see any leaks for a day or two then all of a sudeen its pissing oil on the floor just sitting there (like a new Harley). A rear main seal will not leak just sitting, neither will an oil pan gasket unless you have so much oil in it...
