Making the 1970 Plymouth Crop Duster a Street Machine! | Roadkill Garage

Freiburger and Dulcich take the racecar out of the '70 Plymouth Duster known as the Crop Duster and make it streetable. With its new 440 V-8 and gearing, the car finally ran 10s at the strip. Now the guys attempt to make it slower and quieter for more drivability off the track.

What do you think of the streetable version of the Crop Duster?

[@kcbvids]

love it. The looser converter bridges the gap between too much and not enough

[@mikebrown8065]

Love it!!!❤ One thing I always hated with the Holley was having to change the power valve after it would burp and backfire....thanks for another great video Steve and Dave!!!!

[@craigcontofalsky4387]

Great car! I raced a Super Stock 340 Duster back in the 70s. It ran 11.20s @ 121mph. Can't even imagine running it on the street with the tires back then. 😂

[@ChristopherWhite-ov3wy]

Pretty darn quick.

[@lennyuli9494]

Love the car! Street or race trim is drive it! MoPar or no car!! 🏁🏁

[@emilianocruz11]

We need the full episodes of the crop duster on youtube please

[@joshluna4978]

Yes ! Please do the full episodes, please! From Vespa Squash!!

[@davidgalea6113]

Or at least allow non US viewers like myself to pay for it. I had a paid subscription but you guys cancelled it. You yanks and your foreign policies are bloody mental.

Amen

This is my favorite car you both have ever done...my favorite mopar model...

I really love the "Crop Duster", very cool car, Steve is one of my favorites motortend hosts, And Dave can break things down so anyone can understand what he is talking about or working on. Awesome Content guys. Keep up the great and hard work!!!

Roadkill garage is my favorite show and the Crop Duster is my favorite car!!!!

[@joshholden8561]

This episode was so good i love this series. Steve is a super star.😢

[@NGG1983]

Best car on Roadkill. God i love that body style of Duster. I'd love to see it manual trans swapped.

[@chrishart2064]

The old bodyman says a rubber bumper on the cowl in the center will keep the hood at the correct height. I’ve had the same issue before with a fiberglass hood.

[@albertgaspar627]

funny thing is in the prior century, we'd raise the back of the hood on a big block setup like this intentionally to let the hot air out. so its "period correct" :P)

[@CarsandCats]

That's how I fixed my fiberglass cowl hood from sagging after I had to cut some bracing out.

[@ITSFUNZ]

Sweet 👍

[@jasonlavoie4710]

I love that car it's one of my favorites love the sound the color also the way it pulls out my uncle had a 71 with a 440 back in the day and it was lots of fun to play with 👍👍

Get the fiberglass REALLY hot with heat guns and it becomes pliable … then put it where you want it and quench with dry ice. I guaranty you it works like a dream.

[@karlsanderson8127]

I just want the old ways of roadkill back on youtube

Nice solid Duster.

best friends of rust and gas.. thanks guys. seems easy but I can imagine the hassle...

Favorite roadkill car

[@donparker1823]

I had a 1971 Plymouth duster in 1977 when I got married. It had a 318 with the automatic. Bench seat. It was an ergonomic disaster for me. Drove it from CA to MT when I first joined the USAF. My neck never hurt so much as after that drive.

[@UberLummox]

It might be punched way out to 440, but still sounds like a 383. Good show!

[@lonnieharris6197]

That car is sweet

[@shrapnut7612]

Just watched the full episode on MT Channel, fun time.

[@joebickers893]

You guys are Great 👍

[@steelcitycaprice.899]

Great post and love the direction you took the duster and as a GM lover I must say I always had love for the Dusters and Scamps and always good to see one crusin the streets.👍🏽🔥🔥🔥🏁🏁🏁

[@MotorTrendWatch]

Thanks and both of those are some true classics!

[@kingtut8381]

YOU GUYS ARE THE BEST

[@brianscott9861]

Sweet ride!!!

[@pancudowny]

EFI and overdrive... these are the things that helped make "un-streetable" engines and running big number gears in the drive axle "livable". And who doesn't run a PCV system on a street car? It was the first thing the factory did just to curb smog-producing emissions, and it proved far-better than the road draft tube system it replaced!

[@albertgaspar627]

EFI still likes some vacuum signal, but i'm always shocked folks don't use variable duration hydraulic lifters from Crane or Rhoads. They've been around since the 1960's and go to 6,500 rpm. I have 'em on a 461 cid Olds with a .490 lift/260 duration split cam, and once it's warm, she'll pull away in 1:1 third gear (THM400, switch pitch torque converter with 1,800 or 3,300 rpm stall speed choices) with a 3:1 rear gear ratio and run all day in just that gear. of course it helps to have a spread bore carb like a Carter or a Rochester, and I have an ancient Allison captive discharge ignition that fires through anything. but overdrive is next on the list--probably a Gear Vendors for the price of a THM200R4. And yeah, PCV is sooo much better than the stinky road draft tubes.

[@ChristopherWhite-ov3wy]

Awesome.

[@smilsmff]

I save all of the old spark plug Boots , and keep in the tool box. also You can go into the inner fender above wheel for spark plug access on some Mopars

[@charlielaudico3523]

Great mechanics

[@dbc105]

Dave, uyou and Steve need to look at the A518.

[@MrWoodshoes]

Nice to see a car that isn't all clapped out !

[@albertgaspar627]

agreed, instead of doing dumb things with cars, i'd like to see some episodes where they spruce up some of the stuff they have. i mean, yeah, my own stuff has the "barn find" look, but the rotsun for example really deserves some love.

You already proved that exhaust cutouts don't hurt horse horsepower.

[@christophertaylor9100]

My buddy had an old, crumbling Duster, it was a nice car but he never got anything out of it but daily driver.

[@guest6423]

It looks rowdy. There's something about Duster proportions that I never loved. I think it's that the C-pillars are a bit too far forward, making it look like it has a load in its shorts.

I had a 71 duster with a 383 & 440 crank = 430 cubic inch. Made 525 hp and 550 TQ 3.73 gears, from Dr Diff. car was not all that street friendly, I hated it. I should have built a small block for it. Car was 3100 LBS with the big block and lots of aluminum and glass pin on hood.

[@michaelatkin9649]

I thought Holley stopped making their carburetors and edlebrock was gonna start making the holley style still

[@atf7923]

I see the bangshift cougar has a new hood

[@RSquires]

HOOD FIX. put a couple of adjustable stops with rubber snubbers like they use on the radiator support. Instead of grinding and making a mess, it will hold the hood up in the rear.😂

[@albertgaspar627]

It is funny how we used to think 70mph was pretty good on the highway, but in this century cars have so many overdrives that if you aren't doing 80 mph, you're getting your doors blown off. i remember when 85 mph was automatic license removal if the cops caught you, now you pass 'em and they don't even bother. yay technology.

[@Warrior_Resisting_Colonialism]

3.25 range gears are still "good" street performance gears. They're just not "drag" performance like 3.75 range + gears. I don't consider anything "highway" (non-performance) gears until 3.00 range - gears.

[@albertgaspar627]

agree with your accessment. my olds 442 is running 3:1 and gets 15 mpg, my 86 GT mustang has 2.73:1 and gets 30mph if i coast.

440s can work VERY WELL with 3.23s.

After the guy fixes the hood can you ask him nicely to install a 8 track?

If drivability is the goal... Why not EFI?? Not being a smart aleck, just asking.

[@mickangio16]

Carburetors are perfectly fine if you know what you're doing. If you don't, then pay for a self learning, complicated, unreliable EFI.

[@ReCycledCycler]

Personally the Centerlines were sooo much nicer

[@mickangio16]

Matter of taste. I like the Cragars. Just like when Finn put the dark colored wheels on Blasphemy. Some people loved it but I thought looked yucky even though magnesium gasser day nostalgic. The Centerlines looked period '70s drag on CropDuster but the Cragars look street sweet.
