Subject: Cam Selection and F500

I need help picking a cam for the 351C that I am rebuilding. Its going in
my daily driver F100 so I need something that will offer more torque. I
have been looking in the PAW catalog and crower makes a cam that sounds
about right. Its called the BAJA Beast and is designed for "stump pulling
power and torque...1200 to 3800 RPM."
The specs are:
Lobe Center 112 Deg.
Duration: Advert. Int 258 deg. exh 264 deg.
Duration: .50 Int 200 deg. exh. 210 deg.
Lift : int .477" exh .486"

Does this cam sound right?

Also for those who are interested in the F500 saga: We got it home
sunday. We left Raleigh at 7:15 sunday morning arrived at our destination
in Maryland at 11:30. Loading it up on the trailer and chaining it down
took an hour. Started back at 12:30. Arrived at my wife's uncle's farm
outside Raleigh at 5:30. Rolled it off the trailer and breathed a big
sigh of relief. What a day!

The whole trip cost $70 in fuel too.

The little cones on the axle housing are there for location purposes
and to make the brackets mirror images of each other so they can't be
mixed up. The tab the hole is in is too weak to actually restrain
the bracket IMHO but the bracket is made to mate with other parts on
the axle housing which do tend to retain it's location. I wouldn't
worry too much about the locator pins myself but don't trust the "U"
bolts to hold it in place. It needs something solid on the housing
to butt up against to ensure it will stay put.

I can't remember how the rear is mounted since it hasn't given me any
trouble I haven't really looked closely at it but I thought it was
attached to the spring perches somehow or at least used them as an
anchor?

If you locate the brackets on the axle housing and set it all up and
tighten the "U" bolts then you could have someone put two tacks, one
on each end (radially) of the bracket so the clamping force of the
"U" bolts will keep it trapped between the tacks even if the weld
breaks since the bead will be raised above the axle surface to act
like a lug. These tacks won't be enough heat or stress to affect the
tubing of the axle housing significantly.

The front sway bar goes in front of the axle with the arms under it
and going to the rear to the frame links. I would imagine the rear
would be mounted in a similar manner so the brackets are to the rear
of the housing and the links are in front of it??

Hey Justin,

The one bummer about this year is the "power-assisted" steering setup. I'm
pretty sure the 75's still had the hoaky "sensor" and hydraulic ram setup with
about 45 hoses, along with the manual power steering box. Don't worry, though,
there is hope. You can update the steering box to a 76-79 and solve the
problems. Other than this, its probably a pretty good rig....

If you go ahead, send me a message and I can give you a few more details on
fixing the steering stuff...

Subject: AC system/15" wheels with twin piston calipers

Hey all,

Picked up a complete (dash and all) AC system for my 78 yesterday. Even
got a brown dash, nicer than mine. Gonna be a major project to get that
in, as firewall hole is totally different for non-AC bronc's. Anyone know
if the "outside air" hole in pass side kick panel area is the same for
AC/non-AC 78, 79's?

I also got parts for a Dana 44 HD (twin piston calipers) conversion.
Got one whole side and the caliper and caliper bracket from the other
side. I believe these are the same calipers rotors that are on a dana 60
front(which I should have ina couple weeks), so I am using the one
complete setup I got for clearance measurements.

As was stated to me, 15" wheels will not fit with twin piston calipers
without about 1/2 of grinding. I have 35's and 38's in 15" size. I plan
on selling 38's and getting 44's, so I can go to 16.5" on that. The 35's
are BFG AT's. Normally, I wouldn't even think about such things, but if I
get 1/4 wheel spacers, I can make 15" wheels fit with the twin piston
calipers. Still need to grind the calipers, but they radius in near the
edge of caliper, so actual grinding will be much less. I don't think the
wheel spacers will hurt much. I would only be using them with 15 X 8
wheels and 35 AT's on a dana 60 front axle (15" fits on rear allready).
The 44's would not need any spacing.

Subject: RE: Cam Selection and F500

if you ever run it over 3800 rpm, it is too small. i do not know what
tranny/gears you have but that will run out of breath is you need any
highway speed IMHO.

that is about the same as a stock detroit cam according to those numbers.
i would add up to 10 deg duration, and .025 or so of lift and call it a
better choice. i feel that cam companies are conservative. but, it
depends on rear gears, tranny, tire height, etc.

That would work quite nicely.... But the 428 has much more power potential.

"on a 2 valve engine, peak flow has the greatest influence on peak power,
whereas low lift flow influences power at engine speeds beyond peak power.
extra low lift flow allows the engine to 'hang-on' longer at high rpm."
- --David Vizard.

and, yes you can flow (looking at % improvement) with this size bench, and
maybe even a small block head (superflow sells SB chubby adapters for it),
but not heads like i have that flow like sewer pipes during superbowl
halftime (which is what i said in my first post.) sure, you may see a
pressure differential change accross the port, but there is a thing called
laminar flow and turbulant flow. strange things happen when flow changes
to turbulant flow, and a bigger flow bench is needed to simulate this. so
like i said, i wouldn't work for ME, MY 460 heads. or i would have them on
my bench now!

i do see the low lift thing in magazines. just not in super chevy or pop.

Here is a little secret that may take some thinking to get:
The low lift air flow is the most critical portion of the lift, the overall
time that the valve spends at low lift is greater then the time spent at
high lift. You never read this in the magazines!
So this bench will work surprisingly well for the big heads.
Of course were I consistently building 400+HP engines I would get a SF 300
or 600; and that is what I have unlimited access to now.
You got to start somewhere and this unit is IMHO THE place to start

Sean,
Have you tried the junkyard (don't recall the name) that is in
Harrison OH? Take I-74 to the Harrison exit and turn right off
the ramp (past Wendys). Down a couple of miles (past the
BFI transfer station), you turn right (I think there is a flashing
light at the intersection). The yard is down on the left. I don't
remember them being in the phone book, so you may have
missed them. They specialize in Ford stuff, and they had a
good selection of old F100s when I was there.
Did you also try 'Mad Man's' in Ross OH? My only
expericence was that they were overpriced and rude, but
they might be able to help ya.
Good luck.

Yo Dale:

So your carb has these metering rods? The Motorcraft 2150 that is original
equipment on my truck has no metering rods. I have found another truck w/
the identical carb (matching part #s) in a local junkyard, and it is the
same w/ no metering rods in the booster venturis. What is the part # on
your carb?

>Ford describes the booster venturi as; "The booster venturi

Hmmm... That sounds like what I want! I wonder if the design I have w/ no
metering rods is a later or newer system (since mine is on a 1980 truck) or
just a simpler/less sophisticated system. Maybe on my carb w/ no metering
rods, they sacrificed the "more precise" high speed operation for
"improved" low speed response. I wonder whether the performance-oriented
1982 Mustang carb is more modern/sophisticated or just older and more
effective. Hmmm... as usual, more questions than answers.

If the air horn is the top of the carb from the air cleaner gasket up, then
that's where mine is located. Otherwise the description seems to coincide
w/ how it works on this carb. I wonder if this HIC device augments the
vacuum advance signal switching (by the coolant PVS, between carb spark
port and manifold vacuum), which is supposed to do the same thing, increase
idle speed to prevent overheating, or if the HIC replaces the vac signal
switch.

So, Dale, does your carb have a HIC on it? Should be on the right side,
just behind the choke tower.

Yeah, I thought about that, too. But the rebuild kit is a special order
item, so they don't even have them in stock in the shops, and you gotta pay
in advance for it. :-( Maybe it is just the "high performance" rip-off
after all.

OTOH, if the metering rods were used in other 2150 carbs, maybe I could get
a cheap kit that would have the parts I need. Are the metering rods
included in the rebuild kit?

Thanks.

Having been a former Buckeye myself at one point, The Columbus Swap meet is
in the opinions of many one of the 2 or 3 best swap meets to go to for ford
parts in the whole wide world.....unless you had access to the secret Ford
warehouse somewhere, but then it wouldn't be a swap meet, it would be heaven!!

John, could you tell me a little about Jimmy Rose?? Where in Tennessee is
he located, it lokks like a Nashville area code. I'd be interested in
looking him up.

Cast iron manifolds have special needs. The proper way to install
them is with anti-seize on the manifold side of the gasket and none
on the head side (for non graphite types) to allow for heat
expansion. You also need to torque the bolts progressively tighter
in the center to looser at the ends to allow the manifold to move and
use anti-seize on the threads as well. I put a set on my 460 this
way several years ago with a max of 22# torque on the center bolts to
17# on the extremities and they stayed tight for many years. Headers
now are a different story from what I hear, mine have stayed tight
though so far :-)

Subject: '77 F150 Help (long)

Hello, my name is Doug and I am new to the list. I recently inherited a
1977 F150 4x4 with the 351 engine and need some expert advise. The truck
will hesitate and stall if I try to accelerate while making a turn from a
stop. It will restart very easily. After I studied the carburetor for
awhile, I noticed the accelerator pump linkage was loose in the clip. So, I
pushed the linkage firmly in the clip. The truck now does not stall and
generally accelerates fine but there still is a slight hestitation
(acceptable), but ocassionally stumbles and backfires when accelerating from
a stop.

I am trying to adjust the timing and idle speed on the vehicle. If I
remember correctly, the fast idle is set at ~1,800 RPM and the curb idle is
~600 RPM. If I'm measuring this right, the ignition timing is set at 17
degrees BTDC. This seems overly retarded to me, but the pointer is on the
left side and am assuming the single pulley mark is TDC. Does any of the
listers know what the specifications are for the idle speeds & timing?
According to the manuals that I have looked at, they all specify specs are
on the underhood label. This is great, but this truck has no underhood label.

Would appreciate any expert opinions on this problem. Thanks for your help.

Well, I'm,, not exactly sure, but this is how I think it goes.

1/2 ton is dana 44, coil spring, single caliper, small rotor.
small axle shaft

3/4 ton is dana 44 , leaf spring. twin piston calipers, larger rotor,
larger spindle/hub with inside bearing larger, outside bearing seems same
as 1/2 ton. locking hub mech seems same as 1/2 ton. small axle shafts
same as 1/2 ton.

1 ton is dana 60, leaf spring, twin piston caliper, larger rotor (not
sure yet if twin piston caliper and larger rotor are the same as 3/4 ton)
larger spindle and hub than 3/4 ton. Different locking mech than 3/4 ton.
Larger axle shafts.

I think the only common parts are the twin piston calipers, rotors and
"maybe" the caliper bracket. Until I get dana 60 front in my hands, I
won't know for sure. I'm not even sure if dana 60 front uses same hub nut
tool. I think the spindle/hub is different from dana 44 HD to dana 60. I
would imagine it has to be, due to axle shaft being larger.

I could measure them, but you could just as easily call TSM. The guy is
real cool and doesn't really care if you buy rotors/calipers from him or
not. He will give you sizes/years ect...

Subject: Body Panels

Hello Everyone!

My '78 shortbed project is coming along nicely, and it's come to the
point of doing the body now. The body I have for it is basically
crap, but solid and useable, but I would like to find new panels for
it that are of the same quality as OEM.

The question is if I'm going to be putting this much money into a new
body, and I don't have the ability to grab one from down south, what
do you guys think about going fiberglass? What are the advantages and
disadvantages? I don't know of any manufacturers that sell them, does
anybody have any information on manufacturers that I could get a
catalog from?

Thanks in advance.
