As I recall you need to change the crank and pistons to the 400
versions as a minimum effort but due to larger volume you may want to
look into a cam as well, not sure if it's necessary tho.

If it's what I think it is it won't stay for one thing. I've done
this on cars and the first big bump you hit one side or the other
flips back and it makes a real interesting ride! The other thing is
that if you don't change the front to match the height you will have
a rear end sticking up in the air like a stink bug and steering and
handling will go away. It won't affect the load capacity one bit
unless you want to sink it to the nubbers in which case you will
probably break the springs and over load your axles as well.

It may work if you devise a way to prevent it from flipping back over
with a stop of some sort but your handling will definitely suffer and
you will need new shocks as well to allow for additional wheel
> travel and extended length from the original mounts.

They usually do this on 4x4's for more suspension travel and ground
clearance but on a 2 wheeler I don't see any benifit?

Subject: Timing, vacuum and stuff

I just installed a "highly accurate", partially gravity operated, 2"
sunpro vac gauge in my bronco and, other than breaking the light bulb
while hooking it up and pushing the new one in too far (??) so it
interfered with the highly accurate mechanism, it was a piece a cake
:-) I also bought the necessary fittings from AutoZone to hook my
PVC up to manifold and re-route the booster line to the front of the
manifold (just worked out that way) so I now have properly evacualed
crank case and new, HD line to the booster. Still haven't adjusted
the distributor vac but that's next on the list to eliminate the low
speed spark knock (I hope) BTW, the Holley I have doesn't seem to
have a timed port so I can't play with the idea I guess. Next time I
take it off I'll take a closer look.

Thought I'd share some observations about the vac:

Don't buy SunPro! It's really, really cheap and the needle has about
4# worth of free play in it (partially gravity actuated) and I'm a
little amazed that pushing the light all the way in to the shoulder
interfered with the mechanism?? I'm inclined to find a 3", test
gauge with a rear port or a 3" dash mount made for high accuracy when
I get serious about this but I just wanted something to do a little
tuning with so I grabbed what they had, bummer :-(

If you use a vacuum gauge to tune with remember that it's highly
sensitive to all sorts of changes in temp, pressure, wind, grades
etc. so you need to test on the same stretch of road under the same
conditions and use land marks to make notes on changes. Here's my
method primarily aimed at cruise tuning for economy:

Find a relatively level straight stretch of road where you can run
for a while without disruptions. (I happen to live on one) Get up
to the speed you want to check and maintain steady throttle pressure.
This is absolutely critical since the slightest variation will alter
the reading. Pick good land marks and take readings only at the
land marks you select and note the direction of travel to eliminate
grade from the equation and note the readings in a log for reference.
Also note the temperature and any wind conditions so you can try to
duplicate them on the next run. This is as scientific as you can get
without a lab and dyno IMHO and will give useful information but is
only usefull for steady state, part throttle testing, primarily for
economy improvements. It's my contention that improvements in this
area will help the performance in other modes as well depending on
gearing and intent etc..

I read an article once which stated that anything you can do to
improve the vacuum reading in any given set of circumstances will
also improve economy since it's an indication of improved efficiency
so I installed 4.11 gears to get the revs up and, by golly, I got
better vacuum readings but the economy went down!!! WHAT??? Didn't
occur to me that the extra revs on a 460 would eat more gas :-(

What year is the vehicle and does it have auto locking hubs? If you
go to full time you will want them locked all the time to prevent
damage to the differential spider gears. If it has manual locking
hubs you can just leave them locked or get the full time hubs for it,
they're interchangeable as far as I know.

Why do you want full time?

I have a 1978 Bronco- manual lockouts.

I am debating getting heavier axles, i.e. Dana 60's. I think a Dana60
will require 16" rims, and probably a new Master Cylinder, am I correct?

I guess it comes down to the strength and durability of the transfer cases
themselves. Tell me something about the transfer cases.... I was
thinking about a full-time with the OEM chain.

HI all,

My 74 has a main and auxiliary gas tank. The previous owner, who bought the
truck new in 74, hardly ever used the auxiliary gas tank. Does anybody have
any suggestions or thoughts on what I should do to this tank before I start
using it?

Probably but not necessarily.

The NP-205 part time is probably the strongest light truck transfer
case ever built. It can be upgraded with different input and output
shafts for heavier applications as well. The chain drives are
inherently weaker and typically have more backlash in them. Unless
you spend a lot of time driving on ice the full time won't gain
anything I can think of except perhaps convenience since you won't
have to worry about whether the hubs are locked in or not.

On Ice they are hard to beat since they differentiate between the
axles for less slippage due to axle wrap and allow for driving on
pavement in between icy spots with no wrap up to damage differential
and transfer case gears.

They aren't especially hard to get out so you could take it out and
slosh some cleaner (like gumout) around to make sure and dump out any
debris which might be in it but some have drain plugs in them and you
could rinse it out that way too. Personnally, if the tank looks to
be in good condition it is probably ok to use as is but I'd make sure
I have a good filter in line between it and the pump before filling
it up.

Subject: CDI Ignition Module?

Hi All,

When I bought my 74 Truck a few weeks ago, the was a small box mounted on the
fender well. On the box it say "CDI CONNECTIONS". Some of the wires go to the
coil, I haven't traced the rest of the wires down yet. Can someone tell me what
this box is, what it does or anything else they might know about this box?

Thanks!

Does it have the typical ford plugs on the wires? 74 was the first
year for the ford electronic ignition. If you have a magnetic pick
up in the distributor and the box is a grey aluminum deal about 5" x
7" x 1.5" thick with two plugs, one with either 2 or 3 wires and the
other with 4 I'm reasonalbly sure it's a Ford unit although I don't
remember the CDI wording on it anywhere?

The early versions have different color coding so I can't help you
with that part but the plug with the 2 or 3 wires is the 12v , 6-8v
and noise input and the one with 4 wires goes to the coil with a
green wire and the other three go to the distributor. The red coil
wire should go either to the hot side of the ignition in the start
position or a small post on the start relay.

Haynes, Chiltons and Petersons manuals have a pretty good schematic
and explanation for the system and are relatively inexpensive. It
will help you a lot to have a copy for reference. (Check before you
buy it to make sure it's in there) The Ford service manuals are very
poor for this. Apparently you have to buy a special wire schematic
separtately to suppliment the service set.
