What in the Tarnation is goin' on around here......(for posterity....or is that prostatery ?)

1968 Plymouth GTX Show Car "Thumper" - $105,000 (Tacoma)​

Thumper is a real GTX. I created it in the 1980's under the ISCA Rule Book. It was designed to run for points in the nation. Sadly, when it was finished ISCA at that time was no longer in existence. The car was moth balled for 20 years. In 2003 we statred to finally show "Thumper". Even though the car looks time dated it is like brand new other then there is finally issues with the paint. After 40+ years now there is some checking and a problem with the gold leaf lettering. All the mural work is in tacked. For the younger generation this car is a huge draw.

Below you will find the major modifications I made.
Custom full frame (consultation by Art Morrison)
Velvet blue interior (by Bob Jasper)
Paint and mural done by JR(Milt) Nelson and Gary Thompson
All Corvette independent suspension
1963 348/409 with a 671 blower (Less then 2000 miles on it)
Muncie M22 rock crusher with a Nascar 2nd gear in it
Rear end Corvette 456 with duel Carrera shocks
All aviation aluminum floor
Corvette telescopic steering
Cadillac electric glass sunroof
Monte Carlo swivel bucket seats
AM FM CD Player
Dash board, console and package tray are made out of stained glass lit.

Murals are:
Drivers side is "Thumper" playing in the fall
Passanger's side is "Thumper" playing in the winter
Trunk lid is a huge picture of "Thumper"

It took me 3 years to build "Thumper". If you were to build it today it would cost over $300,000 and long time to build.

I don’t have the words….

Cool engine is the only positive thing I can say about that car…

 

[Cheapsunglasses]

This car represents the 70s customs that went a little too far….but it’s cool

 

[Hey-O]

I was a GM guy and some of these parts are fantastic, but nothing on this car is right. While the swivel seats are unique to a few GM cars from the 70's and I do like them, minus the screwed up upholstery. The Grand Prix door handles are very nice, which I've seen done before, don't belong on this car. The 348/409 is great and the Muncie M22 rock crusher is absolutely great. I've done some extreme things to cars, but it must flow and the engine swap make no sense to me. The man was on crack when he thought this was a combination the world would love to own. He took a GTX and took it's life to create a **** box. I could go on, but why...........

I’m a big fan of the old school customs and attended many World of Wheels shows. I wonder if the stain glass dash and package tray has back lighting. Still it’s odd for interior choice.

The engine does have a badass feel to it but that’s missing in the rest of the GetX. I would want to drive it to experience the suspension.

What’s the deal with the NASCAR 2nd gear?

I’d pass.

I read up on the 348/409's but don't remember much about what I read lol. I know they are a bit on the 'different' side of things with their 'slanted' deck surface....

 

[eldubb440]

nothing against Bambi or Thumper, but that thing is set up for a pride parade

 

[Under Pressure]

In the 70’s I don’t remember that kind of customization, I would have laughed at it then, I laugh at it today.
Unbelievable

It ran from 1961 to 1965, came in a few versions and I liked the scalloped valve covers, but not just unique to the 409. They were on the 348, 409, 396 and the 427. We've talked about this before, the beginning of the first true muscle car, before the GTO, came the 1961 409 Chevy Impala SS.

Didn't the long ram intakes on the Chrysler 300 come out in 60?

Yes, but everyone has to give Chevys the credit for some reason . Who cares about the early hemis, the king ram intakes

 

[bearman]

Nothing to say except alot of time building something that you can't do anything with. I can why it was put in storage.

 

[Hey-O]

What’s the deal with the NASCAR 2nd gear?

The old original "Rock Crusher" was a "close ratio trans, the same as the M21. The new wide ratio, similar to the M20, ratio wise.
Both version will have similar RPM drops between 1st, 2nd and 2nd, 3rd, but the wide ratio will have a bigger drop between 3rd, 4th, hence the wide ratio name.The, wide, also features lower overall ratios in 1st, 2nd and 3rd gears, helping to compensate for higher, freeway friendly gears, and still provide a nice hole shot, but allowing that road friendly gear to be utilized in 4th gear.

Those scalloped valve covers were unique to 348, 409, and a rare 427 Super Stock engine, not available in passenger cars. The shape of their valve covers made the motors to become known as "W" motors. The heads had no actual combustion chamber, as the top deck of the block was machined at an angle to the piston top. Thus, the top of the bore became the combustion chamber. This was an idea that went nowhere.
The 396, 427, and 454 has similar canted valves, but were covered by a conventional rectangular valve cover. This was a separate engine family that returned to conventional combustion chamber in the head.
Chrysler's "Poly" motors also had canted valves and had unique scalloped valve covers to hide them. These motors mounted their rocker arms on a single shaft. The Chev motors mounted their rocker on unique ball studs, with no rocker shaft. Chrysler's experimental "Ball Stud Hemi" combined the best features of the Gen 2 Hemi and the Big Block Chev for a new generation of performance engines. Unfortunately, the Muscle Car Era was ending, and this motor never made it to production.

1957 Chev 283 h.p. 283, with fuel injection. 1957 DeSoto. 345 h.p. 345 Hemi. Both with 1 h.p. per cubic inch.

After seeing those seats one person came to mind…
