About this episode

A lively catch-up blends garage talk with road-trip history. Emily and Rose swap stories about ongoing van/engine work—freeze plugs, oil pan/engine reinstallation, and fitting an Astro front clip while dealing with rusty areas and scraping speed bumps. The conversation then pivots to Route 66: its 1926 highway designation, rapid paving by 1938, promotional efforts, and the vibe of rough one-lane stretches and open landscapes. They also mention school memories, convoy plans, and upcoming events like “The Bandit.”

Technical Too Afraid to Ask
Term

fleet

"That was cut in 1985 after his passing. It was in my fleet for a bit. It has since been handed off to members of Riffraff Vanners that viewed him like family as well."

A “fleet” just means a bunch of vehicles that belong to the same group. Here, it sounds like they shared or kept the vehicle with their group for a while.

Term

Astro engine

"...we could have just like in and out of the astro engine. Emily BB19: they get here on Saturday. They definitely weren't like the other astro engine was like, you go try to knock 'em out and just pokes through 'em."

They’re talking about the engine setup in their van. It sounds like they’re working on an engine that’s been swapped in or modified, and they’re trying to fix issues before reinstalling it.

Term

rusty on the backside

"They definitely weren't like the other astro engine was like, you go try to knock 'em out and just pokes through 'em. Yeah. 'cause they were so rusty on the backside."

They’re saying the parts were corroded in a spot you can’t easily see. Rust there can make parts harder to remove and can cause leaks later.

Term

freeze plugs

"Yeah. 'cause they were so rusty on the backside. These were getting there. So it's good to do 'em fresh freeze plugs, that's always nice."

Freeze plugs are small plugs in the engine that help seal passages. If they rust or leak, you replace them to stop coolant/oil issues.

Term

oil pan

"And then, um. Freeze plugs, oil pan engine goes back in and we're gonna try to cut the bolts off the old manifolds and just keep using the old y pipe."

The oil pan is the part at the bottom of the engine that holds the oil. It’s part of the system that keeps the engine lubricated.

Term

manifolds

"Freeze plugs, oil pan engine goes back in and we're gonna try to cut the bolts off the old manifolds and just keep using the old y pipe."

Manifolds are engine parts that gather gases and send them down the exhaust system. If bolts are stuck, you may have to cut them to get the parts off.

Term

y pipe

"...cut the bolts off the old manifolds and just keep using the old y pipe. van. It is gonna be nice."

A Y pipe is an exhaust piece that combines two exhaust streams into one. Reusing it means they think it’s still good and will fit with the new/updated parts.

Term

channeled the frame through the body

"...you've then channeled the frame through the body, and so you've made some kind of channeled section mm-hmm."

Channelling is a custom-body modification where the frame is moved upward through the body to lower the car’s stance without cutting the body as much. It changes how the body sits relative to the chassis and can affect interior clearance.

Term

frame rail

"That allows whatever the shape of the frame rail is to pass through the body, which is an obstruction into the pa, the passenger compartment."

Frame rails are the main longitudinal structural members of a body-on-frame vehicle. When the speaker describes the frame rail passing through a cut/section in the body, they’re talking about how the chassis structure interacts with the interior space.

Term

front fenders

"...He did that on the front fenders. They, they were a full radius. He lopped him off and made it flat across the top."

Front fenders are the panels over the front wheels, and in custom builds they’re often reshaped to change tire clearance and the vehicle’s visual stance. The speaker mentions modifying fender shape to achieve a lower look.

Term

2 inch drop spindles

"is on two inch drop spindles, so my cross member's two inches closer to the ground. And I scrape speed bumps."

Drop spindles lower the front suspension by relocating the wheel hub/steering geometry relative to the suspension. A “2 inch” drop means the front end sits lower, which can improve stance but may increase scraping and alignment sensitivity.

Term

cross member

"...so my cross member's two inches closer to the ground. And I scrape speed bumps."

A cross member is a structural bar that connects frame/suspension components on opposite sides of the vehicle. Lowering the car with drop spindles brings the cross member closer to the ground, increasing the chance of contact with speed bumps.

Term

speed bumps

"And I scrape speed bumps. But the A 67 has a Astro Front clip, and although it's slammed down"

Speed bumps are raised road obstacles that test ground clearance. The speaker’s scraping comment ties directly to suspension lowering and how low the chassis sits.

Term

front clip

"But the A 67 has a Astro Front clip, and although it's slammed down"

A “front clip” is a swapped-in front-end section (often including sheet metal, mounting points, and sometimes suspension components) from another vehicle. The speaker implies their build uses an Astro front clip, which affects fitment, stance, and how the front end is assembled.

Concept

Route 66

"But in a sense it has a very big, anniversary coming up of, its really, its very first thing which means that it was assigned in the numerical designation for the highway system, April 30th, 1926. So we're coming up on a really big anniversary for Route 66."

Route 66 is a legendary road in the U.S. People associate it with classic road trips and American history.

Concept

assigned in the numerical designation for the highway system

"...it was assigned in the numerical designation for the highway system, April 30th, 1926."

They’re talking about when the highway got its official number in the government road system. It’s part of why the anniversary is meaningful.

Concept

commission to promote 66

"There was, you know, there's the thing I read about like some early, um, they created a commission in I think Arizona and Springfield, Missouri, uh, to like, promote 66 and get people traveling it."

They’re saying people created a group to help promote Route 66 so more travelers would use it. That helped build the road-trip culture.

Concept

fully paved

"And the thing is, that by 38 it was fully paved. They did a lot."

“Fully paved” means the whole road got a proper surface instead of dirt or gravel. That usually makes driving smoother and easier.

Concept

one lane wide with gravel shoulders

"But this is another section of it where it's like one lane wide and there's gravel shoulders. But anyway, yeah, the parkway section in Missouri before the S Fudge Factory, it's rides rough, like railroad tracks."

They’re describing a rougher, narrower road section—basically one lane with gravel on the sides. That makes driving more careful than on a modern wide highway.

Concept

liftoff Instagram

"But anyway, it'll be on the, uh, liftoff Instagram. We'll have it on our Instagram and we're going for smoke. And the bandit is on the 26th."

They’re saying they’ll post the pictures and updates on their Instagram page. It’s basically where the group shares what they’re doing.

Concept

convoy

"The first, uh, three. We missed convoy. That was, uh, this week, but there's two more, which I can't remember the names and I forgot to get the pictures."

A convoy is when a bunch of cars drive together as a group. It’s usually for a planned event or meet-up.

Concept

bandit

"But anyway, it'll be on the, uh, liftoff Instagram... and we're going for smoke. And the bandit is on the 26th."

“Bandit” sounds like the name of an event they’re going to. They’re saying it happens on the 26th.
