I need to check my valve to piston clearance in the 360 Mag I am building right now. I was going to use the clay method. If I am doing this with hydraulic lifters, how can I ensure an accurate measurement? Is there a way to ensure that the lifters are fully pumped up before proceeding? Thanks...

Hey,. Wondering if any of you are running the .028 thick Mr. Gasket head gaskets. There are a few bad reviews over at summit on these so i wanted to get a few more opinions. I know their leaks could have been prep or head/block related too. Anyhow the thinness of it makes them attractive, and...

Hey All, Fsm calls for two drops of loctite 518 under the rear main bearing cap. I plan on using it. Anyone know what the reason for it is? Just curious. Thanks, CE

I'm going to start assy on my 5.9 magnum this weekend. I have my bearings from Hughes, prepped block and polished crank. I am aware of plastigauge, but don't have any. What I do have is a full set of inside and outside micrometers, snap gauges, gauge blocks, dial bore gauge, etc (I am a...

Hey All, I've always used aircraft form a gasket on freeze plugs. It has never let me down. The machinist that did my block recommended red locktite. I have plenty of that down in the shop too. Anyone here ever use it and prefer it? He builds some pretty wild dirt track engines. It must...

Hey All, I noticed that the oil hole in my #1 cam bearing isn't quite lined up with the feed hole. The bearing is flush on both sides of it's bore so the hole in the block must be off a bit. Should I try to go down the hole in the block with a long drill and open up the hole in the bearing...

If you are or have, did you have to grind away any of truck motor mount bosses? Thanks, CE

Hey All, Putting a magnum 360 in the 68 Val. The val's original 273 was/is painted mopar red. The 360 mag was black. I was thinking to keep the red, but my engine is going to retain the serpentine acessories and eventually will be an EFI engine. Maybe that'd look better black...

Hey All, Anyone have pictures of how much and what they ground off their Magnum engine, insofar as the truck motor mounts are concerned? Do I grind all three pads down to the block on each side or what. I don't have headers for this thing yet (or heads on it for that matter) so I can't mock...

The engine is a 5.9 Magnum. In another thread a member suggested: "I would also add , 1/8" drill between the lifter pedestals to aid oil return, 3/16"long drill from main bearing journal to lifter galley for more oil volume to the mains (it is step drilled from factory) and debur the casting...

Working on a 360 magnum for my 68 val. I am hoping to do a hone job and use the original rotating assy. Someday I want to do a 408 stroker, but that is 3-5 years off...yadda, yadda... I just measured the cylinder wear with a freshly calibrated dial bore gauge. (I am a machinist, jut not...

Hey All, Got my 5.9 broke down to the bare block today. Took out the freeze plugs I could reach (gotta get the rear ones out when block is off the stand) pulled the oil galley plugs out of the sides. Should I pull the small ones out behind the cam retaining plate? What else should I pull...

Hey All, In the process of getting my 5.9 magnum broken down for a trip to the hot tank etc. The rollers on the lifters feel good. They look okay too. I was thinking about running them until I talked to Tim over at Hughes this morning and found out I can't replace them w/o the heads coming off...

Hey all, I went a checked out some 360 parts for sale near me today. There was a magnum block, but I think the other parts were LA. The crank had a casting # of 418640, ther was also an X and 123 on it in other places. I cannot find anything online for that # The rods were 3418645. I did find...

Hey All, Engine is a 68, 273 w/ the older iron water pump. The books call out a different part # for the a/c cars. Anyone know for sure what the actual difference is? Thanks, CE

Hey all, I just installed a set of exhaust manifolds from fabo member Treblig. I have to reclock my oil filter adapter to account for the new position of the ps exhaust exit. I just want to confirm that thae adaptor will still work correctly when clocked anywhere in a 360 degree arc. I know...

I keep reading about a drip pointer/leg for the timing chain in LA motors. My 273 didn't have one. It does have a slinger. Am I missing something, or did some engines come sans a pointer? Thanks CE

I had to pull my crank to replace a rear main and found this rod bearing. The journal was in amazingly good shape. I just replaced this bearing and let the others eat. What in the heck would cause the weird wear like this? Almost like it got water or something in there and froze and "popped"...

I got a freeze plug kit for my 273 the other day. There are 2 or 3 teeny little plugs that I see no place for on the block. Am I missing something or are they just for a different application? Also found out my kit didn't have the plugs for the heads. Grrrrrrrrrr :banghead: more shipping...

Project creep continues to plague me. I am resealing my original engine, a 273 which is to be a temporary powerplant while I build my 5.9 EFI. So today I was installing the rear main seal. Well I just couldn't get all of it out of there. It kept breaking off so I pulled the crank. MAN one of...

I've been doing a gasket kit resealing of my motor which is a 68 273. My Fel Pro kit came with both steel and a composite intake gasket. The existing gaskets were steel. Do I have to use the steel ones when re assembling? If so how in the heck does the water crossover seal? Does steel on...

Hey All, When I am idling at a red light with a warm/hot engine, my oil pressure dummy light blinks on and off. I have had other mopars do this and haven't really worried about it too much. Engine is a 273 SB with 135K on the clock. I will likely be pulling the engine and resealing it...

Hey all. I am currently doing a 4 speed swap in my car. Old trans is out. There is ALL manner of oil leaking out the back end of my 273. The engine will ultimately be swapped for a 5.9 Mag motor so I don't want to go nuts, but I am thinking all this oil could be bad news for a clutch plate...
