I'm sure 429 and 460 heads are comparable in weight... the stripped 460
heads weigh
64 lbs. each.

Does anyone but me remember us talking about putting together a list
of engine component weights and putting it out there for our use ????

I've got most of a 460 weighted and have the figures ready for anyone who
has the space to put them somewhere..

Let me know

Thanks allot; I figured 75 lbs. just from the back ache I get lifting them.

Having looked into a similar situation a couple of years ago for my '88
F150, I believe the money and effort you would put into the 300 would
not be worth the result, unless you just want to accept the challenge.
The 300 has lots of HP potential - in its carburated form.
Unfortunately the speed density EFI system seems to be the limiting
factor, again unless you are up to the task of doing your own
engineering. While there are performance pieces available for the 6 (if
you would like the source please email me directly) such as better
heads, pistons, headers, etc., but the dollars just don't add up for a
daily driver. You'll be much happier with a V8 swap; the suggestion of
finding the injection setup from a factory 460 is a reasonable one, if
you can find a wrecking yard willing to part with just those pieces -
most want to sell the whole engine. Depending upon what Florida's
requirements are, you could have a hard time getting the 460 inspected
since it wasn't an option in F150's in '92. In that case you may want
to find an injected 351 to swap in. There are lots of performance parts
available for that engine, as you probably know.

Hope this helps with your decision.

I have a 92 F150 w/300cid and 4AOD. Bought it new, and have 70k on it.
Only thing not straight from the factory are wheels and bed cover. I
love the big 6, but would like to have some decent hp. Since the 6 is
far from a performance engine, there seems to be no aftermarket hp bolt
ons. I have packed away on a stand a 460 and C6 out of a 74 Cougar.
Has anyone here tried to shoehorn one of these big blocks into an F150?
If so, problems (other than emissions)? If not possible, anyone know of
a S Florida shop that can help my 6? I know there's a world of
difference between hopping up a 6 and putting in a 460, but I already
own the 460.

Since the 460 was offered in 2wd's of that year, there should be all the parts
available either new at your local FOMOCO dealer or at your favorite salvage
yard from a similar vintage truck.
I'm not sure of all the things you need, but I'll try to mentiuon a few that I
would look at 1st.

Engine Motor mounts and stanchions from same vintage.
Oil Pan from truck of same vintage.(maybe)
You may have to lengthen or shorten your drive shaft, which is no big deal for a
competent drive shaft shop.
You may have to move the transmission cross member, and the C6 being from a car
has the long tailshaft, and your truck probably has a short tailshaft,
henceforth the drive shaft modification above.
You may need the truck exhaust manifolds, but I don't know this.
Radiator and fan shroud from a 460 equipped truck of same vintage.

I don't know about the electronics that control your current engine and maybe
other things.

the head weight if should be about 85 pounds each if they are the steel ones,
and about 20 less each if there the alum. ones.

Subject: FTE Perf - '84 AOD

Just wondered what I could do, other than adjusting the TV rod, to get
higher shifts. I'm O.K. with the 1-2 shift but the 3-4 is way to soon.
I'm not sure that a shift kit would solve my problem. I've seen ads for
valve bodies. What do they do and does it to apply to my AOD. Would a
mild torque converter help with this. If I could get a hold of a later
AOD what year is optimum. I've heard the OD bands are larger but don't
know much else. Thanks.

Subject: FTE Perf - My lights blink. Why?

Hi all.

I have installed a set of road lights (55 watts each) on my wifes
"94 Explorer. Now when I have them on in conjunction with the hi beams,
the hole system starts to blink off and on. This only happens on hi
beams. The low beams work OK with the road lights on.
I installed them with a relay so there shouldn't be any extra draw
on the headlight switch circuit.
I have used relays and extra lights on all of my Fords for many
years and never had this trouble before. Even with bulbs of up to 250
watts each. (I really like those aircraft landing lights out in the
desert at 2 AM.) this has got me puzzled.
One more thought. I rechecked the wiring on the relay and found that
i had it wired backwards. I had the ground term. hooked to the light
switch and the power term. ran to a ground. Fixing the wiring didn't fix
the problem. Could the relay now be damaged, causing the problem.

Any input will be appreciated. I'm at the end of my wire.

But factoring in emission requirements (ugh) now skews the picture
somewhat. For most (stock or near stock) vehicles a small bit of back
pressure is needed for proper EGR operation. How much you might ask; I
test vehicles routinely for back pressure at the O2 sensor outlet and
anything over 3 PSI 3000 RPM is suspect for undue restriction.

But.. measuring with an analog gauge 12-24" away from the exhaust
port(s) as I do has no real correlation with the actual absolute
pressure seen at the port(s) during the exhaust event for each
individual cylinder. I use oscilloscope patterns of the engine vacuum
for diagnosis on occasion and I was intrigued by the vast difference
from peak to peak that results in a 'steady' gauge when I was introduced
to this technique. I would assume that there is a similar variation in
the exhaust given that I *do* see a lot of pulsation on my back pressure
gauge at idle. My question is since exhaust manufacturers talk about
'scavenging' and there are definite negative pressure cycles in the
exhaust does it really matter if there is 1 PSI back pressure overall
and the negative pressure events are doing the job at the right time in
the right place(s)?

I'm not trying to poke holes in your statements; just would like to
know.. working on (boring!) stock engines I'm more involved on the
first 3 cycles of the 4 cycle engine than on the exhaust unless it's
restricted.

Also the injection/carb must be up to the additional fuel required; some
systems are borderline to begin with. Also make sure that
modifications do not result in the filter being in the path of airflow
from the fan especially if you have a MAF.

Let it rip! Most of the ones I've let sit got sent anyway. (Although

If no one else responds I could probably sneak it into the shop's web
site without a direct link (FTP file maybe?) Lots of unused space so
far and I'm in charge of it so I could probably link it from one part
and sneak it by the boss. Something like
www.XXXXXauto.com/engweigh.htm/ Hopefully the originator will come
forth though; I'm swamped enough as it is! ;-) If you run out of space
I can certainly place it on our server for a while for safekeeping
though.

Well... a tiny bit more draw to energize the relay.; might be enough to
push the circuit breaker in the headlight switch over the edge
especially if it was marginal to begin with. Might not hurt to rewire
the highs through a relay. I'd try a new headlight switch first though.

*IF* the energizing coil is shorted to the load then yes. I'm getting
too tired to think the whole circuit through, but I'd replace the relay
then the headlight switch and if all else failed wire a new relay into....
