Was it just the cab or was the whole truck there?

The non-VeeWees
The bike was super cool. It could be turned into 2 wheel drive when needed. It also has reverse. It's Russian...

Many people cannot really conceptualize the speed in which things have to happen inside an internal combustion engine.
This is one of the reasons that plenum intakes are so much simpler to tune vs independent runner styles. It is also why design, style, and height of the plenum is critical. The elastic nature of air in a plenum acts like a reservoir of sorts.
The speed in which an air fuel mixture must accelerate and fill a cylinder is fairly amazing.
Imagine the oscillations felt in this air space. With increasing speed the pull felt becomes somewhat more uniform, but there is always a back and forth of sorts.
Another point to understand is when dealing with more aggressive high rpm camshafts.
In many cases you have an intake or exhaust valve with 250@.050 degrees of duration, as you can see below the valve itself has to be open longer than the intake stroke. This is why with such cams it is required to run richer mixtures. The intake charge is often diluted with exhaust gases and thus will not burn as well on the lean edge of the spectrum. There is also the fifth stroke (of sorts) with these cams, when valve overlap occurs and flow through the cylinder occurs.
A mistake many fall prey to is trying to balance this sort of engine with a 14.7:1 air fuel ration. In many cases a considerably richer mix is required to idle at low rpm. Once the throttle is opened more and 1500+ rpm is attained the mixture can lean out more.
This is also why a stock engine can often have an initial timing of 10 degrees, whereas a more aggressive build may require 18+.
More time to burn a diluted mixture is required.
Understanding valve train events is often the first step to truly understanding engine behavior, and as an extension, carburetor requirements.

The 914 was amazing.
the white riviera was super nice too.
The GN was awesome.
I have not seen an LT1 in a long time.
The yellow grand prix is a friend of mine. He just got it painted again.

My dad had a '76 K20 for about 30 years. We'd completely repainted it, new interior, multiple engine and trans swaps, lifted, wheels/tires, ect.
He sold it just prior to the 'vid for about $9k. He had two other trucks and felt bad only driving that one once a month or so...
I haven't brought it up, but I bet he's kicking himself over that one. .

My buddy Richard Built A VW..
"
Giant VW Built On Dodge Ram Chassis
Richard Tupper built a Volkswagen Bug that’s 40 percent larger than the real thing. “I have a sheet metal shop and one day I just decided to make a bigger VW,” says Tupper, who lives in Gardena, Calif. “It wasn’t that difficult to do because we have really good equipment at our shop.”
Tupper started with the chassis of a 2010 Dodge Ram pickup. He used 3,514 different parts to assemble the Super Bug, which is powered by a Dodge Hemi engine. To exactly size the parts for his giant bug, he used digital images from what he describes as a ‘very cherry’ ’59 Volkswagen Beetle that he dismantled. When he made the parts all 40 percent bigger, they all bolted together really nicely, Tupper says. There’s not one original VW part on the vehicle. They’re all new and handmade.

I remember that poster. I wonder if that is the same car. I bet it is, he has had it like that for decades.
and how did they get the speed limit sign on the wrong side of the road???? LOL.
