Subject: Phoenix Systems Bleeder

Well, I guess I need to watch the video again :-( I tried the
injector last night and it did what I expected and worked as expected
but it didn't get the air out. The video that came with it is a work
in itself and covers every possible situation with good schematics,
glass cut away videos of the location of bubbles etc. and is very
informative and eye opening. Apparently it's not a no brainer or I
would have got it right the first time :-(

They recommend depressing the brake pedal about an inch but I
discovered it's more like 7/8 and very specific to be able to get the
fluid up through the master cylinder. The other problem is the
bleeders themselves whick let more fluid out around the threads than
went up through the lines on occasion.

Even with the cap on the resivoir it sprayed fluid all over the
garage so I suspect I was a little too ambitious about squeezing the
handle............

Then they recommend after feeding you "burp" the bleeders to get the
bubble out near the bleeder and I found there was a fair amount of
air there after pushing solid fluid in and taking off the hose even
when I tightened the bleeder while under pressure so it's a whole new
science to me.

I'll watch the video again and try it again and when I finally do get
it right I'll let y'all know and give you a happiness (or sadness)
report :-) I see in the instructions they have 4 different levels of
sophistication including two made mostly of metal and each level is
more expensive of course. The one I have is the V-10 and is very
simple and made of plastic so it will have to be cared for if I want
it to last. The V-20 is somewhat better quality with more
sophisticated check valves etc. so might actually be a better bang
for the buck depending on price. The case is nice and has real
hinges and real latches so should last a life time with care but the
injuctor internals are very simple and may not hold up. Only time
will tell...........Maybe simple is better in this case??

Subject: dies at idle

Howdy!

Good morning everyone. I have another question for the list. I
have been having a little trouble with my truck (63 F100 w/ 292) in cooler
weather. It seems to die at idle in the mornings when I am driving to
campus. For example today it is about 40 degress (F) outside, the truck
started fine and I warmed it up to about 100 degress and took off. About
a mile down the road I stopped at a red light and it died, it started
right back up, but at idle it sounded like it is at really low RPMs. It
died a couple of more time down the road. By the time I got to school
it was at an operating temperature of 160 degrees. When I parked it, the
truck at still a low RPMs at idle but slowly it started to recover power
and get back to it normal RPMs at idle. The rest of the day it should run
fine without any problems, for some reason it only dies in cool weather in
the mornings.
I have replaced the points and plugs wires, I even put dry gas in
the gas tank to get rid of any possible water. (the fuel pump is also new)
Any suggestions?


Thanks.

Gary, how does this thing attach to the brake system ?

I have a EIS power brake bleeder. I've had it for about 10 years, paid
about $250.00 bucks new. It connects to the master cylinder, then you
just go from bleeder screw to bleeder screw opening them and letting the
fluid run till there's no more bubbles coming out. Works great. Its alot
more costly these days I'm sure, but was well worth the investment
if you do alot of brake work.

Subject: Speedometer Problem

I am the proud owner of a 1963 F-250 pickup truck and this weekend the
speedometer died on the way home from school. (I go to school in PA and live
in NJ) I took the speedometer cable and housing off and removed the cable.
It was not frayed or broken so I greased it and put it back in. Now of course
I tested it first by putting the back up on blocks and hooking the cable back
up. The speedometer worked when it was not in the dashboard but once
reassembled it does not work. I don't know if there is a problem inside the
tranny or what. If anyone has any possible solutions write back here or to me
at: tdnovell devalcol.edu

I'm assuming you have a manual choke. Find where the choke
cable hooks up to the carb (just get someone to put it a
few times while you watch. It should be on the right hand
side. You'll notice that the arm it's hooked up to rubs
against an adjusting screw which, when pushed moves the
throttle just slightly. This is the fast idle. When the
engine is cold and the choke is pulled you need a faster
idle setting.

If its happening after you no longer need the choke to
start and run, then try adjusting the idle mixture
screws 1/4 turn. These screws are at the bottom front
of the carb.

Yo Charlie:

The 351C intake manifold will not work as a drop-in because the 351M has a
taller deck height (by almost 1.1 inches). You can buy adapters from
Moroso or Weiand to get the 351C intake manifold to work on the 351M.

Emissions legality may be a consideration, depending on your local laws.
If you use a 351C intake manifold, it will not be set up for the EGR and
Thermactor ports, which you may need for emissions legality. Also, some
351C heads were not equipped w/ EGR and Thermactor ports.

The 351C heads will work on your motor if they are the 2V heads. The 4V
heads have larger ports and valves and they are not suitable for a low-rpm
truck engine.

Regardless of temp, 500-600 rpm. Fast idle should be
700-800 rpm.

Can you say "right turn clyde"? Any which way you can! There is an
attachment (costs extra) that allows pressure bleeding from the top
if you have the new plastic, single filler neck type. You can press
it into the holes in the older types and do the same thing or you can
push it up from underneath which is what I tried last night. The
video tape is really neat.

The only thing I'm disappointed about is that they didn't send lour
loc plugs so I could store it with the fluid in the lines but maybe
that's not recommended anyway??

I'm sure I did everything wrong last night so I'm going to study the
directions this time :-)

Manifold torque is based on the needs of the manifold more than the
bolts. They need to float a bit or they will break. Headers are
stamped steel and can't break so more torque is ok and actually
needed most of the time. If they are 3/8 bolts you could go as high
as about 35 - 40# but take it up past 30 just 5# at a time and if any
of the bolts seem to be stretching or fell mushy back off. 5/16
bolts are only good for about 25#. They need to be tight but don't
break them :-)

Hopefully not belaboring the point as to roll the eyes of list readers, but
in an effort to preserve a performance beefed up engine yet still comply
with newer smog reduction efforts, is it too oversimplified to say that
with point #2 (below), the introduction of a universal catalytic converter
into a vehicle that originally did not use one would balance the increased
NOx output as to comply with legal smog output levels?

I've calculated this thing till I'm blue in the face and I can't see
were you guys got 9:1 or 10:1 with a 0.010" deck clearance and 70cc
combustion chamber and 0.033" gasket and 3.984" stroke???

I have to add a 0.280 deck clearance to get 10:1??? What the heck am
I missing. I wasn't going to show my ignorance but this is killing
me! Pi * r^2 * h is still the volume of a cylinder isn't it? If you
divide the cc's by 61.02 you get cuin right?

Here's my numbers with 0.010 deck clearance:

424.2 total BDC volume
410.59 swept volume
13.61 TOTAL compressed volume (8 cylinders)

Now, 410,59/13.61 = 30.168????

51.32 swept for one cylinder and 1.70 compressed still = 30.168 so
what am I doing wrong?

Subject: door rubber

I have been looking in the Dennis Carpeter and Obsolete Ford catalogs, they
have door seal kits, but I am not sure if they include the piece I need the
most. On my 78 250 there is a seal that runs along the top of the door
itself, from the first screw the holds the vent window in, around the top,
almost to the door latch. In the catalogs for the 78 it only shows the
seal that goes around the door opening on the cab. Has anybody ordered
these kits, I just need to know if they have both seals for each side, or
just the cab opening seal. I can not find this other seal listed by
itself, and the guy at ford parts counter had no idea what I was talking
about. I hope some of this made sense, I am just trying to save a long
distance call.

Also I missed a digest and may not have gotten all the info, but we
were talking about the 400s and how they had problems with the heads
cracking. I have a 400 in my 250. Was it only ones from a certian plant,
or is this a problem with all 400s? I checked the stamp and it had a CP.
When I get ready to redo my heads should I just go with 351C 2v heads?
What needs to be done to the 351C heads to work well with the 400M? Sorry
about all the questions, but I think I may have a cracked head, or a bad
head gasket. Seems like there are a few of us having problems with the
400. Thanks for any help. Art Lutz

Yes, with qualifiers. remember the original posting was an attempt to simplify the
explanations.

The only real complaint I have (had I should say) with cats is that I am from
California. Cats are a part of the exhaust system which Ca. said cant be altered.
This means that if you have a car with single exhaust, you cant convert to dual
exhaust, even if you add a cat so that there is one on both sides. Also if you
have 1-3/4 inch exhaust, you cant upgrade to 2-1/4 or 2-1/2 because you would then
have to use a cat with larger inlet and outlet sizes, ie a non-original cat which
is forbidden in CA, you MUST use original equipment or an approved substitute. and
yes I am familiar with all the "cat-back" aftermarket exhaust systems, it does
little good to have a dual exhaust system behind your cat when all the gases going
into it have to squeeze through a single 1-3/4 inch pipe.

In my current situation I have a vehicle that didnt come with cats so I am free to
play in that area as I wish. I intend to have 2, three inch cats in my exhaust
system (one for each side) along with low pressure cracking valves to supply the
supplemental O2. All racers are not mindless brutes with no concern for the
environment. My personal goal with my 460 Lincoln powered, 73 F-100 is sub 13 sec
1/4 miles, 20 MPG, and meet current (not '73) emissions standards. It can be done
but not with low-ball "lets meet the Govt. regs with minimum cost per vehicle and
performance be hanged" engineering. The old saw about "speed is money, how fast
can you afford to go" applies here.

Off the soap box, next point

In actuality, one of the best methods of reducing NOx is exhaust gas recirculation
(EGR). At part throttle applications, diluting the air/fuel mixture with O2
depleted air (exhaust gases) reduces the amount of available oxygen. From a
chemical reaction standpoint, the carbon based fuels "want" the oxygen more than
the nitrogen does. In an oxygen depleted atmosphere, the fuel hogs the oxygen
leaving little for the nitrogen to use in the formation of NOx. Part throttle
operation usually implies leaner mixtures which also tend to increase NOx. One of
the early "mistakes" in emissions engineering was the significant leaning of the
air/fuel mixture in an attemt to control hydrocarbon emissions, unfortunatly, the
leaner mixtures caused a huge increase in NOx generation (leaner mixtures burn
hotter increasing NOx (see point 2) and leaner mixtures leave more available O2 in
the exhaust gases which also increases NOx, a double whammy). oooops!

EGR is all well and good at part throttle applications when full engine output is
not required. At full throttle, Air/fuel mixtures are richer (usually) and so NOx
production goes down while hydrocarbons go up. Not a major factor in most cases
because even lead-footed miscreants such as myself have to keep their foots out of
the throttle plates for 99.9% of the time. My biggest complaints against the EGR
technology wasnt the basic premis, it was the poor implementation of the 70's and
80's. When EGR valves fail open, the motor runs like a three legged dog. when an
EGR valve fails closed, NOx emissions skyrocket, neither failure mode is
acceptable.

The pre 78 400 blocks cast at the Michigan plant had some problems with
cracking. I believe it was Chris Samuel that was saying that the newer 2V
heads were a thinner wall casting and had more of a tendency to crack under
extreme conditions than the older 2V Cleveland heads.

Cleveland 4Vs perform best at high RPMs at the cost of low end torque. Not
the ideal truck engine to say the least. IMHO you'd be much better off
"freshening up" a set of 2Vs.

I,ve got a 66 f100 pickup with manual steering that is just all over the road.
I've replaced the gearbox with a good one and added a new tierod end so I know
that the front end and gear box are good. The only bad parts on the front end
are the king pins which have some play- one side more than the other. would
that cause the severe side to side wandering of the truck when you hit a
bump.....


Also, does anybody know of a company that will rent a truck with a hitch so i
can tow this dog back to my house (800 miles) without selling my
soul............

Thanks in advance.

Hey there,

What's causing your problems is BIAS PLY TIRES!!!!


With today's roads, all rutted as they are, the bias tires climb the center
crown in your lane and make you drive like you were a Canadian snowboarding
gold medalist.

Slap on four radial tires and your problem will miraculously be cured.

the people i have talked to (as i have never done it myself, yet...) that
have done it were very satisfied with the results and felt that they got a
BIG gain in power from midrange on up, with only a small loss at the bottom
of mostly throttle response and only a little torque.

it can make a very satisfying engine, but you need to ask someone who has
done it successfully how they did it, as far as cams, compression, etc.

also, 400 cubes use the 4v heads very effectively compared to the 351. 50
cubes make a big difference. even between the 429 and 460 engines the 460
uses the CJ heads much more effectively than the 429. the ports on the 4v
cleveland heads are very close to the ports on the 385 series standard
head. and a 429 with standard heads makes loads of torque at the bottom.

and furthur, if a stroker motor is built, the 4v heads will become even
more effective. bigger cams and better manifolds, headers, etc. can really
take advantage of the heads when properly done as there are at least 2 of
these engines running at the local truck pulls. these engines can really
show the bowties what a real truck can do.

who said a truck needs torque down low? some of the best street racers i
have seen are trucks! some people prefer a hot running engine to a low
speed torque motor for even a daily driver.

i know i do!!
