IMHO you can't beat a well machined custom rebuild of your engine, if
it's not been burnt up. If you aren't confident in your abilities to
build one, find a good engine builder (someone with real integrity, and
pride in his work) and have him put one together for you. He'll check
all of the clearances and won't put things in wrong. Yeah, it will be a
little higher priced, but you get what you pay for.

Most parts store rebuilt engines are crap. Go into the store's back room
and look at the cores that are being turned in. That's where your "new"
engine is coming from. I've seen worn out valvesprings, stripped bolt
holes, and that's just on the installation. In 10,000 miles you'll find
out where it's been when it rattles and makes more blow-by than the
engine you pulled out.

If you must have a crate motor, I reccommend a Jasper, and nothing
else. They aren't as good as a custom built, but they beat the others
by a fair piece.

I grew up around Springfield, MO and those hills stood between me and
Table Rock Lake. They can be a formidable opponent. You are a lucky
man, though If you've lived there awhile I bet you wish it was how it
was 20 years ago. It's a nice town, but it made me a little sad last
time I went over.

When you soften up springs you increase body roll. Lowering offsets it
to a degree, but roll will be more noticeable. If your shocks are a
little weak, it will crow-hop worse because the springs arent
controlling the motion as much as they did. Add to that, the shocks are
mounted to control bounce in one direction only.

You should put on a rear sway bar, as light as the truck is in the rear,
it doesn't have to be really thick, and stagger your shocks to stop the
hop. You see, the staggered shocks will break up and control the motion
that causes crow-hop. Look under some late model trucks and use them
for a pattern. Put on some good fat radials, just wide enough and with a
weight capacity suited to your use, and air them according to the load.
Soften them up a little in the rear when you aren't hauling anything,
and air up the front some. By a little and some I mean no more than two
pounds above or below the recommended presssure, i.e. 32-34 lbs in front
and 30-32 in the rear, on a 32 lb tire. That's the most variance front
to rear that should be run. The idea here is to tune the tire response
to the differnce in weight front to rear. When you haul something, air
them back up.

Push is going to be the demon you'll have to make peace with. Unless
you redistribute the weight, it will have difficulty turning at higher
speeds. The sway bars and shocks and lower center of gravity will help
alot, but it will still push.

It's very important to avoid deep-dished wheels on the front of straight
axle rigs, they cause bump-steer and wander,and are hard on the
roller-type steering boxes, and king pins. (if you haven't switched to a
Saginaw type box yet, I highly reccomend it, but I'd still avoid deep
wheels)

You could have a bad hanger-bearing if you have a two-piece driveline.
A brand new one will shake in 6 months if you haul or rip around much.
I never could comepletely eliminate the shake in my '67 and I replaced
and balanced everything.

I had basically none until I jacked up truck and dicsonnected drag

Subject: FTE 61-79 - Thermostats and Heat Transfer - Cooling wars continue

Just for the record: calories are no longer defined by the heat needed to raise
water, but 1 calorie is now defined to be exactly 4.1860 Joules. (Halliday and
Resnick, Fundamentals of Physics, 3rd ed)

I think you guys are also more interested in the specific heat capacity of water,
which, according to Howell and Buckius, Fundamentals of Engineering
Thermodynamics, for a constant volume process the specific heat capacity is
defined as partial derivative of internal energy with respect to Temperature, or

Cv= Uth - Utl / (Th - Tl)

for water the T and U numbers are courtesy Howell and Buckius, I did the C
calcuation, so hope this helps.

T ( C) U (KJ/Kg) C(KJ/Kg*C)
50 209.12 4.178
55 230.01

70 292.76 4.186
75 313.70

90 376.66 4.206
95 397.69

According to Elements of Heat Transfer (bayazitoglu and ozisik) heat transfer
due to convection is of the form q=h(t1-t2), where h is a function of the tube
geometry, orientation (verticle vs horizontal), and speed of the air flow. As the air
speed can affect this equation radically, much attention is given to fans and fan
shrouds!


All that said, I agree with Steve that the lower t stat simply buys you a few minutes
and only pushes the problem off for LONG periods of high power. For
intermittent, SHORT periods a lower t stat can make a difference. In other words,
don't tow your boat and think you'll be ok, but if it works for day to day driving its
worth the 8 bucks. (And the 35 cents in the glove box in case you need to call for
a ride!)

Personally, I rather prefer a alternator with an external regulator.
That way when the regulator blows up I can replace it for $12 instead
of having to change the alternator...
I also like having the regulator external since it gets the regulator
away from the heat and vibration of the alternator.

The later solid state regulator should be a plug in replacement for Your
older mechanical one. They're about $12 new, or available by the thousands
at the wrecking yard...

I had carb problems with my '85 f150, 300-6.
The previous owner had "fixed up" the carb and added a manual choke kit.
I bought a complete rebuilt carb with a 1 year warranty for under $90
(cdn)at the local auto parts store. It took me about an hour to install
it and set it up. Check into this route before you buy a carb kit. Its
not as much fun as rebuilding your own, but if you don't have the time
or space ( I'm not allowed to use the kitchen table for mechanical work
anymore....)

Thanks to all for your suggestions...It does hesitate/miss a bit when going
about 40...kinda depends on
where the accelerator is. The more I press down, the better it sounds...Yes
I'm running it with the Carter 1bbl. When I got the truck, there was
NO air filter (smart) so I immediately put one in It sounds like the
accelerator pump needs to be replaced and/or the carb re-build.
I've never done either of those B4 but I'm sure it sounds scarier than it
really is. I have a haynes manual that I'm not really impressed
with so far. Not much detail..

Hello folks,

Thanks again for all your input on whether or not I should yank my 390, I
have a couple more things I want to check before I make any decisions, But I
think if it comes down to it I will rebuild it myself. I spent a year
building 3516's for Caterpillar, how hard can a 390 be?

Anyways, the reason for this letter is I am looking for suggestions on getting
a few (50) more HP out of a 300 six cylinder. It runs great, but all top end
goes down the toilet in overdrive. This is my brother's truck, (the one that
got me hooked on flyin trucks) and welike to get a little more oomph out of
her. Right now it's bone stock, and runnin great. Any suggestions would be
greatly appreciated, Oh by the way we don't want to switch to a V-8 because
of how light this 6 cylinder is.

Yo Art:

The only internal differences between the car and truck 400 engines are the
camshaft and timing set. All other parts are the same. Externally, the
cars use different accessory mounting brackets because cars and trucks have
different underhood configurations and different frame clearances. The
cylinder heads are identical.

>Are there any other parts I should look at taking off?
>Thanks Art

I'd take out the whole engine. Then when you're ready to do a ground-up
rebuild, start w/ the ex-car engine and rebuild it while the one in your
truck is still running. When you don't have to do it just to keep your
wheels on the road, an engine rebuild is a lot more fun. You can take your
time and do all the little details, and you can save up for those Primo
parts instead of settling for what the short-term budget will allow or what
the local yokels happen to have sitting on the shelf.

Good luck w/ your truck.

Get an Offy 4bbl manifold and either a split cast exhaust manifold (two
pipes coming out of the manifold) or get headers for it. Call up Crower
for a healthy cam. They have a hydraulic Compu-Pro cam with 202/210
duration (.050") and .443/.448 lift that would work well in the big six.
The next step up would be the 210/210 grind, they claim that it is for hot
street/drag (strong upper-bottom and top-end). Strap on a Holley or
Carter/Edelbrock and your in business. Of course Crower does offer solid
tappet cams all the way up to 248/252 duration (.050") with 105 lobe
centers, but that may be a tad bit extreme for a street motor :) Bet that
six would sound good with that cam in it.

Well, just don't forget the spark plugs, and that thing on the front is a

Hi Guys,

More Cam questions - I am lacking in general knowledge as to what makes
a cam aggressive or mild as far as duration and lift numbers go. What
would be considered a "high lift" cam. What would typical numbers for an
RV cam be?
What specs typically provide low end power vs high rev power and why
would one be desirable over the other?
Any and all info is appreciated.
Sleddog? Azzie? Steve? anyone else?

Subject: RE: FTE 61-79 - Cams Again ? ?

not much time, but here goes some generalizations:

lift and duration numbers for a small block, or a big block will be
different at the RV, or high lift cam level. a .525 lift is approaching
big on a 302, but just starting on a 460. a small roller cam makes more
power than a big flat tappet cam with the same dur and lift #'s

so, matching cam to engine is as important to matching cam to driving
needs.

overlap is how long the intake and exhaust is open at same time. overlap
is usually noted as lobe centers in degrees. it is not actual overlap, but
an indication of it. usually in the 106-114 deg area. the bigger the
number, the more it is geared towards low end torque, reducing overlap, and
keeping cylinder pressure at lower rpms. the smaller lobe centers mean
more high rpm potential and more overlap, and a rougher idle due to
increases overlap - loosing cylinder pressure at low rpms. i small engine
generally needs larger lobe centers. bigger engines get away with more
overlap.

for a 460, for example, i would consider a hydraulic cam with .525 lift and
dur at .050 of about 270-280, and lobe centers of around 112 a torque cam,
but at .580 lift and 300 dur at .050 with 108 lobe centers a cam to run in
the 3500 to 6500 range with a rough idle and poor low speed "drivability"
(a very subjective term)

remember , the same cam put into 2 different engines (of the same cid and
engine family) will run very different depending on the intake, heads,
exhaust, carb, etc.

well, did this explain anyting? or just raise more questions?

Subject: FTE 61-79 - Cams Again ? ?

Hi Guys,

More Cam questions - I am lacking in general knowledge as to what makes
a cam aggressive or mild as far as duration and lift numbers go. What
would be considered a "high lift" cam. What would typical numbers for an
RV cam be?
What specs typically provide low end power vs high rev power and why
would one be desirable over the other?
Any and all info is appreciated.
Sleddog? Azzie? Steve? anyone else?

Thanks in advance

Subject: Re: FTE 61-79 - Straight six dog

Jumpin' Ford Person- (can't find your name in e-mail!)

Straight six a dog? Nahhh!!! 8-)

Finally! I get to talk about something I know a *little* about! I have a
'78 f-150 4x4 with a 300 I-6 running a offy manifold, 600cfm carter carb,
and '88 dual exhaust manifolds w/ dual exhaust running out the side infront
of each tire! Power is generated from about 1200-3000rpm with 4,000 rpm
redline on the stock cam, and with the clifford performance cam it came up
into power at about 1800-3500 with a 5500rpm max. (I went to dual exhaust
and 4bbl at the same time as the cam) As far as sound? Hearing my setup
tach up like that sounds just like a Cessna taking off. Unique, funny
even, but defenitely interesting! As far as weight? 300's weigh MUCH more
than a 302, and you can't build a 300 to compete speed (horsepower) wise
with a 302 with any kind of relative ease. If that's what you're looking
for, go with a 302 or 351windsor- same bolt pattern on bellhousing and
you'll enjoy the sound much more.
Tuning is a real pain too- If you decide to hop up the truck you'll find
this out in a hurry! But should you decide to go that route- I have a set
of Headers and a Holley 390cfm carb with quickchange vacuum kit and the
jets and springs you'll need for sale! Carb was new and only run for 1
week. I changed my mind and went with the Carter because I'm eventually
going to use it on a 460 and put the single barrel back on when the 460's
done.

Whatever you decide- if you have any questions I can be of use- e-mail me:

Subject: FTE 61-79 - Np435 Clash

As I've posted before my 435 has some clash going into high sometimes
when the trans is fully warmed up. From looking at the exploded view of
it in my manual, it has to be either the splines on either the
mainshaft, input shaft or the clutch gear that couples them. But it
seems that if any of these were really bad it would do it the same when
cold. I don't want to ruin my trans, (it's the original one) I know
that for sure. But I also can't affford to throw parts at it either.

The other day I pulled the fill plug, it has always run fluid out, but
I'd cap it back up. This time I let it run out(cold, and on level
ground)and it ran out quite a bit of oil. It was clean, and appeared to
be 80-90w. When it was filled it must have been on uneven ground or
very cold out, causing it to take in more than it needs. I've driven it
for three days and so far no clash. It still has a little bit of a
dog-leg in the gate from N to 4th on occasion. Now, it's likely a
coincidence that is hasn't scratched yet, but has anyone had this
experience before?

If the clash stays away, or at least improve, that would probably point
to loose bearings wouldn't it? It shifts everywhere else perfectly, and
is as quiet as can be. Usually, in my experience, you'd have some other
symptoms if it needs rebuilt.

Advice, opinions?

One more thing on the 435, is the only vent the one that points down
from the tailshaft housing? It doesn't seem to have one in the case at
all. If so, how does it vent the case? The tailshaft vent doesn't go
into the case at all AFAIK.

I thought the NP425/NP205 both took 140W?

Mine used to leak between tranny/transfer big time, so I always
overfilled it. Never had a problem, but I did rebuild it with new
synchros, so yours may be marginal. BTW, mine grinds when it is cold.
It's fine when it's warmed up. weird!! :-)

That's because the 140W oil is too thick when cold. Syncros are having a
hard time syncronizing with all the extra drag on the gears. I experience
almost the same thing with 80W-90 . Mine doesn't grind, it just doesn't
want to go into gear. You have to put (light) pressure on the shifter for
a few seconds before the gears mesh.

Oh goody! Real formulas and numbers!
So it looks like the difference in specific heat capacity between 70C (158F)
90C (194F) is a little less than 0.5%
That's actually somewhat more than I expected it to be, but still rather
insignificant for our truck cooling puposes...

Uh oh, It appears I've erred.
It looks like convected heat transfer goes up linearly with temperature
differential, rather than as the square of...

Hmmm, I'm certain I've seen the "temperature differential squared" formula
used before. Is that correct for radiant heat or some other manner of heat
transfer? Or am I just way off base on that one?

Thanks for the education! I filed the formulas away for future reference...

After converting the front drums to power disc, and replacing all steering
and suspension items with new parts on my red 1969 F250 (execpt for the
gearbox), The truck still seems to have too much play in the steering. (I am
comparing the performance to my green 69 which has the same setup, and is
tight.) Rumor has it that if I turn a slot headed bolt clockwise (after
losening the locknut), that will "tighten up" the lose steering. Is this
true? If so, then how far should I rotate? Is a new gear box the only thing
that will make me happy? (everything else is new, WTF)

BTW: Power disc brakes are awesome!

Did you replace the rubber rag joint on the steering column?
I've done two of these conversions, one for a friend. The
results are well worth it and you can't tell the truck isn't
stock unless you look under it.

I may be wrong about this, but doesn't the 69 use the same rubber u-joint in
the steering column? Mine went out and if I hit a bump, I would find myself
in a different lane. If you have one I will almost guarantee that's what the
problem is
