Sun - February 17, 2008This is hard.It is difficult to work on a truck when there is
no covered area, the parking area is grass, it rains every third day, tornadoes
are near, it drops below freezing for a few days a couple of times a week, and I
have been sick.
I am trying, believe me. Posted at 10:41 PM Tue - January 22, 2008The formula behind carburetion(CID x rpm x VE)/3456=cfm
CID-Engine Displacement in Cubic inches rpm-maximum revolutions per minute, or redline VE-Volumetric Efficiency, how well the engine breathes. Most engines range from 75%-85%. cfm-cubic feet per minute. How much air the engine pulls through the carburetor. The closer the engine cfm and the carburetor rated cfm, the more efficient the engine runs. So, the truck starts here. I know the displacement but I have to guess at the max RPM and VE. (250 x 4500 x 75%)/3456=242. The one carburetor, a Rochester Monojet, originally on the truck has a cfm rating of 210. So even with the conservative estimates on max rpm and VE, the truck was under carbureted. After replacing the old exhaust manifold with tube headers and the old intake with a more efficient design, the truck does breathe better. I do not know an exact amount, but I will assume at least 5% better then before. The engine was bored out .030 in. when rebuilt, so now it has a displacement of 258. Using the formula again… (258 x 4500 x 80%)/3456=283 If I use three of the stock sized carburetor, the rated CFM needed will be 630. To achieve this cfm from the engine, I will need to improve the VE to 122% and build the engine to withstand 7000 rpm. The only way to achieve above 100% VE is to install a supercharger or Turbo. Since a both improvements cost a lot of money, I will choose another route. The Monojet carburetor has a smaller version that is rated 160 cfm, so three of these carburetors handle 480 cfm. Seemingly easier numbers to achieve. To come close to these numbers I would need to…. Increase rpm to 7500 at 80% VE Increase rpm to 5500 at 105% VE Since this is not an exact science and there are factors that I have yet to apply to this formula (actual atmospheric pressure, true increase in VE, temperature of air entering the engine, etc.), I will allow for a margin of error of around 32 cfm. Increase the rpm to 6500 at 80% VE or Increase the VE to 100% at 5500 rpm Now I am off to find the redline of an inline Chevy 250 with stock internals. Posted at 07:16 PM Fri - January 11, 2008the truck is back!Would you rather have a fuel system that delivers
fuel and air when you stomped the gas pedal or would you rather have a system
that sends fuel to the cylinders in order for the cylinders to pull air in
faster, thus sucking fuel into the air being pulled into the
cylinder?
Or Fuel injection or Carbureted? I personally think that the carburetor was used by the Man to keep us down! Posted at 11:02 PM Sun - January 6, 2008The TruckActually fired up and ran after sitting for a
month. My goal this month is to draw up what needs to be done as far as body
work. If you have any ideas, let me know.
Posted at 10:23 PM Sat - August 18, 2007Northern Migration, Part 3I order to unload the truck the boat needed to be
unhitched. SO I made the decision to put the boat in the garage and leave room
for a car. I ran into one big problem. The driveway does not go straight into
the garage. In order to put the boat to one side, I had to push it up a slight
incline and push it sideways against the front wheel. Now the truck is unloaded
and I have all but my truck at the same address!
Posted at 01:00 PM Northern Migration, Part 2, Chapter 3 and 4As the sun dropped below the horizon, I glanced
in my mirror at the side marker on the boat trailer, only to find them not
working. I debated with my self and Booda if I could make it the last 75 miles
before the light vanished. Booda said no. With that I pulled into a parking
lot and investigated. What I found was that the connector on the Uhaul had a
short inside the plastic. I attempted to fix it, gave up and called Uhaul. As
the gentleman was trying to talk me through re-wiring the trailer, I managed to
get a connection. However it ranged from all lights flashing, all lights on,
all lights dim, to all lights off.
With the randomness of the lighting situation, I stopped again a little further down the road and found that the Left hand turn/brake light was not functioning. By jamming a wire in the connector, I was able to get lights and the right side brake lights. Good enough and I really did not want to wait for Uhaul to show up. Posted at 12:56 PM Northern Migration, Part 2, Chapter 2This is a fact that all drivers need to remember:
If you are able to drive 70 Miles an hour with the parking brake applied, your
parking brake needs to fixed.
The parking bake on the Uhaul has a buzzer and auxiliary light to remind the driver that that parking brake has been applied. However, neither of the two worked on this truck. Needless to say, I drove many miles with the parking brake engaged. As a result, parking became an issue. Posted at 12:47 PM Wed - August 15, 2007Northern migration, part 2In an attempt to complete this journey we rented
a 14' Uhaul truck. This vehicle will be able to handle all my belongings, pull
the boat, and transport some of my mother's supplies. However, the
Service Engine
Soon light was on, and the engine was running
rough. Around to the service bay I went only to find out that one of the plugs
and the coil were bad. A little over an hour later, I was at the house in
Conway.
Posted at 11:57 AM Tue - August 14, 2007installation Rear Springs that lift the rear end up 2 1/2
inches
New distributer and wires resulting in a BIG increase in power Posted at 09:40 PM Northward migration, Part 1After spending two days loading the truck and boat,
I made it about 5 miles before the left rear wheel sheared off the lug bolts.
If you have ever changed a tire, you will remember that the bolts and nuts are
vitally important to keeping the wheel secured to the truck. With nothing to
keep the wheel attached, it took off on it’s own trip. Moreover, the
truck continued in the same direction while the other cars went several
different directions. The sparks were
impressive.
I made it to the side of the freeway with only three wheels. The results, including the damage from the tow… Bent exhaust tip Bent trailer hook Brake drum with a flat side Brake backing plate with a flat side Two remaining lug bolts No lug nuts No wheel spacers Missing brake pieces Dented rear quarter panel Broken rim Split tire The impressive part about the entire incident occurred after I had stopped. The wheel stopped in a lane on the freeway. Everyone was seeing it and able to avoid it, until… A tuner/ricer hits the wheel head on, and becomes airborne. Pieces of the car blew off as it struck the tire and when it landed back on the pavement. He did make it to the shoulder with his engine making all kinds of weird noises. A LRPD showed up, set my tire down flat, the tuner knocked it upright and it rolled to the inside shoulder, and drove to the car. I guess a truck with a wheel on the other side of the road is not a real problem. Two State troopers showed up to help him. Today, the truck sat at Sears waiting for them to tell me one part was missing and it would have to wait until tomorrow to be repaired. Next attempt will be made possibly Thursday. Posted at 09:37 PM Sat - July 28, 2007Cross my fingers and knock on woodThe truck has been running strong and no new
issues have arisen. With that accomplishment, I am able to turn my attention to
cosmetics and upgrades for the Northern Migrations. In route to me at this very
moment, is an electronic High performance Distributer. I already have the new
wires and plugs. This means that more energy will be delivered to the cylinder
resulting in more gas being burned quicker.
Waiting to be installed are new coil springs. The original suspension springs have taken a beating from Daddy Teague's business, several family members using the truck to move, and general age. I know Dina and dupes used the truck to move out of state. I think Lee used to head to college in Louisiana. I have used the truck on a few occasions for my moves. Any body else have assistance from the truck in their move? Posted at 08:15 PM Wed - July 25, 2007FREE CATSWhile the truck was been sitting in the carport,
The neighborhood cats transformed the gravel under the truck into a community
litter box. If you are interested I will be glad to box up a cat or two and drop
them in the mail for you. Just let me know.
Posted at 07:18 AM Fri - July 6, 2007An Advertisement for Dremel ToolIf for some reason you have not experienced the
pure power of a little device called a Dremel Tool, then you have not
experienced a true power tool. Ginzu knives have nothing on this device. I
have one corded and one battery operated Dremel tool. For power, the corded
cannot be beat. I have ground out splines for a transmission, sanded down
bottle dryers, polished stainless containers, and sharpened a lawn mower blade.
For the portable, I use it mostly on my hiking
stick.
This tool put the truck back on the road. Since lengthening the splines, the clutch works as smooth as it ever has allowing me to drive around the city of Little Rock. Additionally, it has opened up carburetor jets to allow the metering rod to slide through, thus eliminating a backfire and overheating in cylinder 6. Posted at 12:56 AM Wed - May 16, 2007Study in Rochester M/MV carbs in a multiple carb set up on an inline Chevrolet six cylinder (250 ci) As promised, the studies of the linkage system
for the 3x1 setup. Soon, I will be able to post the final results. But if
anyone has ideas to improve the setup, please let me know.
Pictures and studies of the Carbs have been moved to this site. CARB DRAWINGS Posted at 01:18 AM Tue - May 15, 2007The Truck in a magazine centerfold.Or it just might be a side picture
somewhere.
The Hot Rod Power Tour will be ending in Little Rock, AR on June 8 & 9th 2007. My goal is to have the truck ready for the last leg from Memphis to Little Rock. Ideally, I want to drive the entire route, but with the outdoor pool opening, I know I will not be allowed any time off. Just think, Daddy Teague's truck just might be gracing the pages of Hot Rod magazine! I am charging the video camera and gathering up the tripods for both cameras to record the event.
