Diesels make suction, not vacuum, the rmp is controlled by the
injector pump, which is actually controlling the fuel returning to
the tank. More fuel to the tank, less rpm. All the Ford diesels use
a vacuum pump and resevoir for the AC controls and power brakes.

I've used these vacuum pumps on engines that are too radical for
true "street" use. One example was my brothers 455 lds, It made
8" of vacuum at idle, the 320degree cam didn't help matters at all....

You Are Correct, Sir.

All W heads are essentially the same, 351W heads had larger valves
than 221, 260, 289, and 302 heads, PLUS the head bolts are 1/2" as
compared to the smaller CID's 7/16" bolts. I seem to remember that
ARP makes 1/2" barrel, 7/16" thread bolts for this application, but I can't
remember if thats accurate.

Right on, a rule of (my) thumb is 10lbs per 1000rpm....

Not any of the diesels I have ever worked on. They all start with the same
amount of air, only the fuel is regulated. The fact they dont have an intake
butterfly is also why diesels have terrible engine braking ability. A few
aftermarket companies have solved this buy installing a butterfly on the
exhaust.

Subject: FTE 61-79 - Oh Magoo. You've done it again!

So I figure I'm about 85% complete in my 79 Bronco rebuild, and I go out and
buy a 75 F250 4x4. Pick it up when the Title clears.
Is there no end to this?
Anywayz.
As mentioned 75 F250 , reasonable Body but will get a coat of paint;
eventually. Drivers fender is wrinkled some but no kinks so it may pound
out... someday. Interior is good throughout, even the dash pad!
Drive train is a swapped in 460 supposedly a 197?, but, who knows could be a
429, I'll run the numbers when I get it. Seller did say it don't like
regular so it could be a good one. New Edelbrock 4BBL Carb on a factory
manifold, otherwise stock engine. Didn't bother to ID the rear axil but the
front is a closed knuckle D44, drum breaks, guessing at 4.10 gears. Assist
type Power Steering, complete with minor leakage, (seals are in order
here!). 4 Speed Trans. looks like its never been opened, cause the tags is
still on it.
The seller pressure washed the whole bottom side of the truck making it real
easy to see who had been where doing what, nice thing was that it had been
done long enough ago so that I could clearly see the leak points(-:
50% 12.00Rx16.5's on Chrome "Modular" wheels, no big, would have liked ether
more, or less, but these hold it up!
Drives nice, tracks straight, breaks don't pull!
Over all a good work truck... for now, but those Glasspac's have just got to
go!!!
After the Bronco is completed it will get some TLC, you know like:
Swampers, Integral Power steering, possibly a C6 (I have one just sitting),
Winch(s), Flat Bed. Etc, Etc...
Is there no end to this??
You'd think after 20+ years I'd learn!

Muel
79 Bronco
& Now, 75 F250 4x4.

PS.
Hi Deacon! Good to hear things are moving, along!

Actually the fuel is injected when the air is at the right temp to ignite,
about the same timing as a spark plug. The air is already hot enough to
ignite the fuel when it is injected. I cant remember off the top of my head,
but I recall the injectors opening at approx. 225 psi, to overcome the
pressure in the combustion chamber.

Subject: FTE 61-79 - Headers for FE

Well I am finally going to break down and buy headers for my truck. I
had originally wanted to wait until I could afford top quality headers
but I just can't wait. Can you guys recommend a good set of relatively
inexpensive headers that will last a few years until I can gather the
money for a very good set. I want something that is not going to "cook"
the starter. I currently have duals with triple chamber flowmasters. I
will probably just have the headers installed and the existing pipes
modified to fit.

Suggestions?
Thanks

If the 330 is a high torque engine, and it was in front of a 5sp direct and
a 3 sp aux to be able to keep the engine in its power band, wouldn't that be
a terriffic engine for towing a camper, HD equip
trailer, etc? Next quest. Can a Clark or New Process HD 5sp be mated to a
460 w/o buying or
making special adapters? Thanks, Bob

Engine vacuum is created by the restriction of closed butterflys. Even gas
engines wont develop vacuum at WOT. If a diesel needs vacuum for any
accessory, either brakes or climate controls, a vacuum pump is installed on
the engine, looks similar to a smog pump.

Subject: FTE 61-79 - 400 to 400C-4V Conversion

I am in the middle of putting 351C heads on a 400
motor. I found the pistons and Weiand adapter plate,
however the Weiand instructions say that I must
replace the stock C/400 dist with a Mallory dist. I
checked the number and its an old style Mallory Dual
Point dist. I really don't want a dual point dist. My
questions are:

Do I really have to make this change?
I am using an Edelbrock performer manifold, can I
modify this in some way to fit the old dist. It
already has a Unilite module.

Can I use any other dist. Like an MSD or other Mallory
with Transistor triggering.

Subject: FTE 61-79 - Ford Truck Tough

Drove over to my dad's last night and discussion turned
to the odometer that indicated 40050 miles. It turns
out that the speedo/odo was broken for about 50K.
The whole truck has about 300K on it.

I remember when the original engine gave up the ghost,
back when it turned about 100K. So for the past 20 years
and 200K has been (and continues to be) on the second
engine. Still runs strong! Ford truck tough.
Not bad for a rebuild at a time of desperation at the
top of the grapevine towards LA in the late 70's.

Subject: FTE 61-79 - speedogear replacement?

Just checked my speedo gear, its taking a beating, my cable is a stock
cable with a stock nylon gear.. makes sense right, well I installed a
toploader transmission about 2 years ago and the speedo gear from the
cable is slanted and the tranny gear is straight, as a result the gear
on the cable is getting chewed up. The gear has seventeen teeth and
needs to be straight... here's another little twist, my speedometer is
off since the changing of the tranny for every mile I travel its off
1/10 of a mile. What size do I need? and where might I find one?
