- "You asked for it, you got it! We're continuing the 360 Magnum revival as we conduct the first run stand test, and you won't believe the unbelievable sound this engine produces!
In this episode, I'll walk you through what I did too get the engine setup and ready for the testing process. From there I'll fill the fluids and check for leaks, and prime the oil system before the first start. Once it's fired up, I'll continue checking for leaks and set the initial timing.
At Montsweag Garage, we're passionate about classic cars and DIY engine testing. If you're a fellow enthusiast, you'll love this content. Watch as we revive this 360 Magnum engine, capturing the essence of vintage muscle cars.

I'm a retired mechanic. Before there was silicone gasket maker there was Indian Head gasket shellac. Permatex bought the company. Why you say are you telling me this? You do not want to put RTV silicone gasket on your engine freeze plugs or any thing to do with the cooling system. That silicone plugs the radiator cores once it gets loose. All of us old head mechanics use Permatex Indian Head Gasket Shellac on freeze plugs. I coat the whole freeze plug and run the brush around the engine block hole for the freeze plug. I have never had a leaking freeze plug and It's my belief that it helps the freeze plug from forming rust. Note to all, If you change your anti freeze every 3 years you will never have rust in the system.
Hello John. Welcome to the channel and thank you for the valuable insight! I will definitely look into the Permatex Indian Head Gasket Shellac. I plan to drain the engine and seal the core plugs just before I drop it into the car. Still have a bit more structural repair to do before I get there though. I will have to do the same when I do a proper rebuild on the 273. Any tops for removing rust from the cooling system of an old engine that sat for 30 years? I blasted out the inside of the 273 with a pressure washer until the water ran clear but it still turns the coolant rust colored after a month. Evaporust makes a coolant system flush that is supposed to convert the rust in the system. I was thinking of going that route.
The engine sounds good! Not a bad run stand for home- made! It will be a great engine for the a-body!!
Welcome back Tony! Thanks for the comment! This just ignited the itch to get the rest of the work finished so I can get the engine in the car. I can tell already it is going to be much more of a monster than the 273 was. It's way more snappy and the 273 never shook the run stand like this one does. What did you think about the lack of music in this video?
Sounds like a happy engine. I always loved how the 360 sounds with open long tube headers.
Welcome back Duke. Thanks for the comment! Hope all is going well with you, and we get to see some more videos soon. The engine is definitely sounding good now that the timing is right. I can't wait to get it in the car now. Still got a ton of work to do before I can do that, though.
Sounds pretty damn good!
I definitely agree. So much more snappy than the tired old 273 that came out. I am super excited to get this thing in the car. Just need to get the torsion bar crossmember swapped out and the suspension back together. Thank you for the comment. =)
That sounds Great! Your engine stand is brilliant, and inspirational! I have never had a run stand...
Thank you for the comment Frank! I would say welcome to the channel but it seems you have been here a while. That run stand is literally built from parts pf a privacy fence we took down when we moved in here. I suppose I could draft up some plans for those that are interested. Would you want a set? It definitely makes tuning and identifying problems easier. Better to find them on the run stand, than once it's in the car. =)
Waste not, want not... Great recycling! I'm intending on welding up a stand... But as a one man operation all my life... In fact I have the metal already... For years now!@@MontsweagGarage
I wish I had he metal to make a stand with. I could definitely use the welding practice. Lol.
@@MontsweagGarage I'd like a set of plans please
@@jamesbehrick9588 Give me a bit to get a set put together. You are the first one to ask so I haven't made them just yet.
Sounds so pretty
Thanks Dale! I can't wait to get it in the car. Need to get my butt in gear and get the floors and the crossmember replaced so I can get the engine in. How's the coffee life treating you?
@@MontsweagGarage 18.8% better!
I can get behind 18.8%. Lol.
Nice job man! One note, never,,,, and I mean never! Tune a dodge to factory specs, that's a starting point at best. Instead tune by ear, you'll know you've got it right when the throttle response is instant and it fires up just touching the key or starter button. I've never used a timing light in over 40 years and most of my friends come to me to finalize their tunes, of course these are carburetor engines with distributors so I am well versed in they way they should run because I know in my memories what a good running one sounds like. From what I van hear on your engine it's a good solid motor and should last you a long time even if you abuse it. So well done👍
Hello again David! Once again, thanks for the comment. I'll be honest. I am still really new at this and I am learning each engine is different. I can tune my 273 by ear but when I tried to tune this one by ear, I ended up with 25* of initial timing. Lol. I will likely stick with the timing light until I get a few more engines under my belt. It also falls in line with my occupation as an engineer. I use a ton of test equipment in my day job and I tend to trust it more than I do myself until I get a feel for what I am working on.
Excellent content!!!
Thank you Bob! Welcome to the channel. Hope to see you here again!
congrats sounds good
Thank you for the comment Stephen, and welcome to the channel.
Nice rumble. Would/will make an A body get along very nicely.
@1080sucks Welcome and thank you for the comment! I am excited to get it into the car but it will be a while. As I dig deeper into the rust, I find more and more than needs fixed. What started as front floor pans and a torsion bar crossmember has morphed into those, plus inner fenders, control arm mounts, quarter skins, trunk extensions, rear crossmember, rear spring perches, and rear bumper mounts. Thank goodness for tax season!
Is this Dead Deboss Garage? I kid, good video!
Hello Clay and welcome. Thank you for the comment. I am just a new guy working on his first project car. While I do watch a few car channels, I have not seen much from Dead Dodge Garage or Deboss Garage though I am aware of both of them. I actually have been watching a whole lot less of other car channels lately. More interested in working on the Dart. I would love to get it up and running again for the summer car shows. Not hopeful but one can dream. =)
@@MontsweagGarageKeep it up! I’m getting ready to swap a 360 Magnum into a 87 D150 so I appreciate the content. I’m in Maine myself, so maybe I’ll get a chance to see your car at one of the car shows when you get it running!
That would be awesome! My goal is to be able to hit Darling's All-Mopar Car Show in Augusta this September. I was there the year before last but the car was apart last year so I didn't make it.
Great videos man! Real stuff for real people and I'm gonna make more mistakes than you did LOL
@langstonjones69 Welcome to the channel and thank you for the comment. I am glad you are enjoying the videos so far. Mistakes are normal for anyone starting out. Part of the reason I built the 360 is due to mistakes made rebuilding the 273. It's been a really fun learning experience so far and I am trying to share what I learn so others don't have to learn the way I did. I hope to see you around. There are plenty more videos coming own the pipe.
Engine sounds great and I love the engine run stand. Did you come up with the design?
Hey Chumley! I haven't seen you in the comments in a bit. Welcome back! Thanks for the comment. I am loving the sound of the engine so far. Still needs some carb tuning but we'll get there. As far as the run stand, It is literally built from left over fence materials I have laying behind the outbuilding. I hung the 273 from the engine hoist and built the stand to fit, right under the engine.
@@MontsweagGarage Nice, that is what I like to do as well - come up with some backyard engineered tools making use of materials on hand at times. Hey it saves a lot of money and works just as well. Keep up the great work.
It worked great for the 273. The 360 has a good bit more torque so the stand rocks a lot more when I rev it. Let's hope it holds up. Lol.
When Initially Installing Distributor,Top Dead Cyl One..Compression Stroke...Why Did You Use '10 DEGREES Before Top Dead ????Should Be Zero ??????
Hi Gary! Welcome and thank you for the comment! What I did when I dropped the distributor in is set cylinder 1 at 10* BTC to set the initial timing for the first start. That is why it snapped off so quick and idled well on the initial start. It ended up at 25* because I am a dunce and advanced it there trying to set the timing by ear. I don't have enough experience with the 360 to do that yet so I'll stick with the timing light for now. 😁
When you pulled the distributor out, did you have to remove the gear before inserting the Allen rod?
The intermediate shaft was left out during the initial assembly, as I knew I wanted to prime the oil pump, but yes you do need to remove it if you want to use the allen rod to prime the oil pump. I probably should have shown where I installed it after priming the pump.
Did you run a line from the trans cooler back into itself for test start ? Asking cause I’m putting my 360 back in and I ripped the lines and need to make new ones
Welcome, Sam. Thank you for the comment! I used a short piece of fuel hose to connect the two trans cooler ports. It works well enough for a test run. I wouldn't drive it that way, though.
Thought you had to use break n oil for new rings
Welcome back Thomas. Thanks for yet another comment. I was under the impression break-in oil was for flat tappet cams. I am the first to admit that this is only my second engine rebuild and I don't know all the ins and outs. My 273 ran fine after breaking though I used a high zinc oil as well as a zinc additive for the flat tappet cam that was in it. I'll definitely keep an eye on this one. It currently has between 160 and 165 psi static compression across all the cylinders so I think the rings have a pretty good seal. I don't really want much more than that with the cash iron heads. I appreciate the info. I will definitely look into it more.
@@MontsweagGarage idk if it true I didn't think u had to but I've had people tell me that an that u not supposed to use synthetic but idk I never rebuilt the bottom end of a engine yet an my starter been turning pretty rough wen i cut it off think im gonna try backing the timing off
Backing the timing off sounds like a good plan. Too much will make the engine sound like it is struggling to turn over, especially once it's warmed up. What is your initial timing set at?
Idk
This not letting me send messages but I haven't checked I'm running a hei Chevy style an I run out of adjustment
Oil pan doesn't leak? It seemed a little sketchy the way you did the oil pan gasket. But if it seals, it seals.
Welcome back Charles and thank you for the comment. The oil pan does not leak. Not yet anyway. Between the pan being bent during shipping, and the gasket graft, I was a little concerned about it. I found the process on magnumswap.com. They detail how to use LA parts on a magnum to keep the engine looking more original to the car. We'll see if it holds up once it is back in the car and under load.
She sounds so mean.
You Aren't kidding! I can't wait to get her in the car. I anticipate it will have about twice the horsepower of the 273 and a ton more torque. I still have to finish the control arm mounts and inner fenders, get the front suspension freshened up, then I can drop her in. from there I plan to install a Holley Sniper EFI and drive the wheels of of it!
