Dale's Demon Returns! Installing The Shed Built 360 To Go Drag Racing In My 1971 Dodge Demon 340

[@matthewb8229]

And just like that, there's a Prius owner sobbing into his glass of chablis.

[@musclecarmitch908]

I had the same thing happen with the clutch disc springs in my 68 charger, I had the Borg & Beck pressure plate too, after researching why the springs were hitting the flywheel bolts I learned that they had a bigger diameter than the original springs that go with the Borg & Beck pressure plate. Really glad you pulled the original engine in the Demon, now you can get nasty with it without worrying about damaging the original!👍

[@DeadDodgeGarage]

Damn right! Let’s see if I can find 6000+ RPM now! 😅 yes they are definitely larger diameter springs, but that flywheel is missing at least 1/8” of material off of the face. That could be a problem.

Great work. It sounds awesome. Nice to see everyone pitching in.

That jam during the fast motion scene was fire. Glad to see the Demon getting ready to race!

Another rainy, rusting, success!

Very exciting video we all missed the demon and can’t wait to see the test drive video. Hope to see her ripping through the track soon!

Nice work Gents 👍🏻 fully looking forward to your trip to the strip 🤙🏻

Proud of you buddy. Keep up the good work

Outstanding work guys. Can't wait to see it on the road.

Very nice. Thank you.

Good to see the demon getting some love 👌

[@randyman828]

Very cool 👍

[@farfromdonemotors6796]

Thanks for reminding me about drag racing. I still need to reset the pinion angle on my Dart

[@DeadDodgeGarage]

Mine has angle shims on it. I should probably at least verify that it’s right-ish. I dropped my snubber to get that out of the floor, hoping that doesn’t result in too much pinion rise. Lots of testing to do here… and a lot to learn.

[@brentforte5950]

She's singing can't wait to see her dance. I bet 8s maybe a flat 7 in the 1/8 mile with the other gears.

[@DeadDodgeGarage]

Has to beat the 9.13 I got the first time out. Haha. It’s kind of funny when you roll up to the line, they ask where your helmet is and you tell them you don’t need one 😅 the car ran high 11 quarter mile times in the 70s. If I can whittle it down to anything approaching a comparable 1/8th time (upper 7s,) I’ll be extremely excited. Ultimate speed isn’t the goal as much as fun, but I know the car is capable enough.

[@rodneybyrd9516]

I know you changed the flywheel with a 360 unit, those things used to be very difficult to find and expensive as hell, so we used to drill the 318/340 flywheels according to the Direct Connection manual. Pretty tricky laying it out (degrees and radians) to center punch, and the depth needs to be precise. Never had vibrations or #5 bearing issues, luckily.

[@DeadDodgeGarage]

Right. I have heard of that but have never had to do it. I actually have a factory one (it’s a rust factory and has some hot spots) as well as the aftermarket unit I used which had a bolted on weight. I also have one of those sandwich weight plates to use with a neutral flywheel if necessary. We have lots of options these days. Haha.

[@rodneybyrd9516]

@@DeadDodgeGarage Luckily I have a KwikWay wet grinder here at the shop, and a bead blast cabinet. I saved a couple of 11" BB flywheels that way. The 10.5s are so cheap, I just go new on them usually. I did score a 5.9 Magnum 10.5" unit off Ebay a while back, just in case!!

[@OrrinCahoone-dd4tm]

Imagine that,340 to 360 and you can't tell the difference, oh yeah,the color.😂 Made quick work out of that with a little help. Nice. Enough talking, back to work on my 73 charger.

[@DeadDodgeGarage]

Fine, fine 😅 no one has called me out for putting a red engine in it yet. Kind of surprised by that, really. But yeah, they essentially look identical. I could just lie and tell everyone it’s still a 340, and they’d never know.

[@OrrinCahoone-dd4tm]

Most of your followers seem not to be so critical. I thoroughly enjoy what you do. Keep it up, good job. Good choice on shitcanning those marine 440 pistons,only 8.5 compression on those motors.

[@DeadDodgeGarage]

@@OrrinCahoone-dd4tm for what we're doing, 8.5:1 would be acceptable. They're going in the scrap pile because they're ruined... We will be putting in a taller (but not domed) KB piston, and hopefully ending up somewhere in the 9.5:1 range.

[@jts9120]

I've had nothing but problems with roller rockers for my 410 magnum. I feel for you

[@DeadDodgeGarage]

I hope they’ll work well now that I’ve gone through them. One just can’t trust aftermarket parts to be good to go out of the box. If I have problems, I’ll put a set of stock adjustable 273 arms on it. The rollers are nice but I’m more concerned with valve float than anything.

[@jts9120]

@Dead Dodge Garage Yup gotta inspect everything now twice. Bought a new hughes roller cam, and it had a huge gash in one of the lobes.

[@dantupper1784]

Just post-intro: VrroomVrrooom!! (camera keels over, stares at the sky..OK, shop ceiling, was funny though....) 273 stuff, after nearly 6 decades- to the rescue!

[@DeadDodgeGarage]

Yes I liked that accidental ceiling shot a lot. Haha. Hell yeah! If I have any problems with the roller rockers I will go right to factory 273 rockers too. I actually considered putting a 273 in the Demon - I thought it would be really fun to dress it with edelbrock heads (valve clearance in tops of cylinders probably required) and other great parts to see what it can do. That could happen eventually. Or heck, maybe that goes in the Barracuda to be era correct and SEGA legal…

[@brianandglendaharkin9457]

727 T/Flight you will be better of an not miss a gear easy an your motor will love you for it .👍🏻💯🇦🇺⛽️

[@DeadDodgeGarage]

If all I wanted was to go fast, I would go automatic. If I wanted to have fun and challenge myself, on the other hand… this is a real four speed car, and it will always have one - unless I lose a leg or something.

[@gregloy5790]

You will get better at being a drag racer. More importantly have fun.

[@DeadDodgeGarage]

That’s all I’m in it for! If I wanted to be fast I’d have a big block, boost and an automatic. Haha.

[@staceyrenner5418]

Huzzah!!

[@AverageJoeBuilds]

Also I do not need this style of motivation to keep the Dart and make it cool because... peer pressure man. It's real!

Dang good thing you didn't "Decide to put in the gabage can" that "spare" 4 speed, hahahahaha

[@jumpinjojo]

I’m surprised you didn’t drop the engine with the K-Frame.

[@DeadDodgeGarage]

I would have if I were overhauling the suspension, but you have to disconnect brake lines, unhook upper arms, and remove torsion bars and steering column, which is a whole lot more than I had time for and would basically start the setup on the front end over at zero. I’ve done the dance pulling it out the top of an A body so many times, it’s kind of my happy place. Notice we didn’t remove or so much as kiss the hood. Haha.

[@jumpinjojo]

@@DeadDodgeGarage Good point!! A little jockeying, but I guess it’s less to dismantle. My Dart had a 440 in it, so there was absolutely no way it was coming out from the top. I replaced it with a 360. Omg, so much room now!! Lol!!

[@rinscoe]

What cam did you end up with in the 360? Do you even know?👍

[@DeadDodgeGarage]

I do! 🤣 I even have the cam card, if you can believe that. It’s a larger Thumpr I’ve listed the cam part number and specs in one of these videos but don’t have the info handy. Recall lift is split, something like .515/.525 with the 1.5 ratio arms.

[@rinscoe]

@@DeadDodgeGarage Cool thanks. Now get back to work you

Ohhh so that's what my idler was supposed to look like mounted up 😅😅😅 shhhh we just pretend I bought the correct part since it steers lol

Great job! Drag racing (especially with a manual transmission) takes lots of practice. But you can do it. I got my reaction time down to less than a tenth of a second. Can't wait to see you on the track with this demon. Those 4.88s will jump like a jack rabbit on crack! You're gonna need some drag radials.

[@DeadDodgeGarage]

It’s wearing some Mickey Thompson ET Streets. But they’re getting a little long in the tooth… I may be tire shopping in the near future. I also definitely have a lot of practice in my future. I’m hoping the 360 will hold all of the magical cooling and lubricating juices in for a while and I can get some runs in. I love shifting gears, and I can definitely get better at it.

[@majortwit]

AdmIt it. You named this engine in a previous life, didn’t ya? “Plymouth SonoRamic Commando” Look it up, it’s real :P

[@DeadDodgeGarage]

I don’t have to look it up, haha. It had shiny gold stuff on top! I will do a cross ram big block some day… it’s on my bucket list.

[@jesusavila7955]

What cam and the head any works?

[@DeadDodgeGarage]

It’s a thumpr around 515/525 lift if I remember correctly. The heads got matching springs, a mild clean up porting job, port match, and a three angle valve job. There are more details on the engine in the build video - the name is something like building a 360 in a shed - and in the last video on the “Garbage Can Cuda.” I can tell you it definitely seems to have more poop than the 340 I took out.
