I've never compared them, but have been led to believe that they are the
same heads, therefore the same valves. Chiltons or such should confirm
this.

I read this all the time on the Mustang groups, and frankly I'm tired of
it. People keep whining about Ford losing the power battle, but they're
still selling twice as many 'stangs as Camaro/Firebirds .... 60% of which
are V6's ... that means 40% of production is split between the Cobra and GT
... to most marketing people that means that the public in general doesn't
want the big power motors and high speed, just the image. I don't know how
the truck numbers work, but I have a hunch they're similar. Personally I
hate the Extended cab/short bed trucks that have become so popular.
They're a pain to drive, and a sacrafice in everything (rear seat room ...
bed length ... etc.), but everyone around here seems to want one, or have
one on order. Ford, like every other successful company is going to have
to produce what the consumer wants, not what a select group wants. Guess I
happen to be in that higher powered group on both counts (Mustangs and
Trucks), so they will always leave us wanting more, which we can get
through SVO and aftermarket manufacturers. Besides, we wouldn't all want
to buy the same truck would we ? Isn't that what makes this group so much
fun, bein able to hop up our trucks to suit our needs and wants ?

I've also seen much reference to quality as the reason that most of the
Cobra/GT owners are going with the Mustang. I've never looked, but they
say that the Camaro/Firechicken has just a cheap plastic looking interior.
I always thought the Mustang's had that, so I'm afraid to look at the
F-body's. Also if they're buying because of the quality, and the Mustang
is admittedly the lowest quality product, what does that say about the
other cars ????

Sorry I'll get off my soapbox now ....


Just my 2cents

That's right, I always think 350 when I think Chevy ... my bad (actually I
think 327, then think, no wait, its 350 now...:)



Actually
>I think the small block went that way also in its last years of

The 350 kept the goofy exhaust porting, and has now been replaced by a 347
engine with normal exhausting. Kind of interesting they claim they
increased efficiency by changing the exhaust ports, but didn't think they'd
gain enough by going to over head cam, so they went with aluminum pushrods
instead ... thought that was odd ...

Also interesting, the Corvette was the first (I believe) to sport the new
347 with aluminum this and that in 1997 ... 40 years earlier the Pontiac
Bonneville was the first to sport fuel injection on a .... you guessed it
347 .... how's that for ironic ?

Sorry for the non-Ford, but thought it was pretty cool history ...

From: "Tom Ewing"
Subject: FTE Perf - Detroit Locker

Hi all. I'm building a 58F100 for the street/strip. It currently has a
429,C-6, and Dana 44. I picked up 9inch Ford 31 spline rear
assembly at the salvage yard, and I was planning at some point
in time on buying a complete new center section with a Detroit
Locker and the gearing of my choice. Thus just using the existing
housing, brakes, axles. But, a drag racing friend of mine just replaced
the Detroit Locker in his 11sec quarter mile car with a spool, and
wants to sell the locker. This guy is great at buying cheap and selling
high, so I'm somewhat leary of being his next candidate for success,
but if over time I could install his locker in the unit I have and then
over time worry about changing gear ratios for the strip if need be.
I got the rear out of a 73 Ford half ton with and automatic, and I
haven't removed the center section yet, but I can kinda figure on
what the gear ratio will be. I've never disassembled one of these
3rd members, but I would guess with a book and or video I'd be
willing to give it a try. My concern is how well will the existing ring
and pinion hold up to my estimated 450-500hp? The donor truck
looked pretty beat, and when I pull the center section of course I
can visually give it a good going over. I believe my friend had the
work on the rear done and probably knows more than me about
the mechanics involved, but I'm not sure he's correct in saying that
he thinks my 73 9inch carrier will need to be replaced if I use his
locker? If I need to buy a seperate carrier too, it seems to me
I 'd be better off just saving for the entire center section after
market complete with a locker new ring, etc for probably about
$900? He told me how many passes he has on the unit. I think
he said maybe 75? He eventually twisted off the pinion( I guess)
if I understand him correctly, and that's why he went to a spool.
This is a trailered 11sec 55 Chevy 454, so there's no street mileage
wear, but just the racing. I looked at the Locker-it looks OK, but what
can I see by just looking? They look pretty durable. He thinks its
probably just fine, and would work well for me. I thought I'd ask
all of you, because I'm on a budget and I'm not opposed to using
used parts if it makes sense. But obviously I don't want to waste my
time and money on something that just won't hold up satisfactorily.
He's a little unsure about the price, but he's talking like he'd like to
have around $250 for the used unit. Seems kinda pricey to me, but
maybe I'm wrong. What do you think?

Has anyone put the large valves from the SCJ into the smogger heads? I have
a set I want to play with and am in the process of looking to buy the
cutters needed to cut the heads for hardened seats and cut the bowls for the
larger valves. If everything goes okay then will machine them for screw in
studs and finish up anything else needed. Just looking for pros and cons.
Thanks,

Like maybe weld two Duratech blocks together and make a modular V-12?
Yipes.
Now, where did I put that Soap Box...ah.
Don't be too hard on the "luxury sport-ute" crowd, guys. At least
they're buying American-made trucks instead of Saabs, Bimmers, and Lexii.
Besides, the more happy truck owners there are out there the less likely
Congress will allow Nader, AlGore, and the greenies to further castrate
our beloved American icons. As if the CAFE and smog-sniffer laws weren't
intrusive enough, now they want to make trucks smaller, lighter, and
lower so that they won't do as much damage to little cars when they
collide. Also on the agenda are laws to make trucks conform to all the
same emissions, mileage, and crashworthiness standards as cars, and to
force automakers to develop, build and sell "zero-emission" vehicles that
nobody wants. Worst of all, there are plans to equip all vehicles with a
Federally Mandated *transmitter* attached to your Federally Mandated
non-reprogrammable OBD computer which will broadcast your vehicle's speed
and emissions compliance to any cop who carries a receiver. Said cop can
then TURN OFF YOUR ENGINE by REMOTE CONTROL if you are (or have ever
been) in violation. Scary. This is your government helping you.
I'm sure Ford would love to sell us the stripped, overpowered F-series
work trucks we want, but thanks to CAFE they can only build a certain
number of trucks per year. Which customer would you choose, a rich
yuppie who buys a new $40,000 Navigator every few years and brings it in
to the service department every time it needs a lightbulb changed, or a
junkyard dog like many of us who wants a basic truck he can fix all by
himself and will keep until it resembles a rusty ball of duct tape and
baling wire? Until Uncle Sam allows Ford to build and sell as many and
whatever kinds of vehicles they choose to, we'll just have to live with
the weenie engines and jellybean styling and hope that the supply of old
trucks and parts doesn't dry up too fast.

Subject: RE: FTE Perf - Detroit Locker

the locker i imagine would be good after the use it has had, but then again
if the pinion and ring broke there most likely is some crap left in there
that may have done some unseen damage.

for a good unit the price is not too bad, but could be better. the actual
work you could do i am sure with a book or visde or such.

i myself would rather buy a new unit (and my pull truck is almost all used
parts!) but price is always the biggest consideration in the comparison -
the price in the short and the long run. used parts are almost always a
gamble.

i know this wasn't much help, but....

You know, after I wrote what you are referring to, I heard a rumor of a
new V12 engine. Can't even remember the manufactuer. A shade of things
to come?

Someone mentioned 2 Duratech V-6's for a V-12 ... well I'm sure you've seen
the Ford Indigo and GT-90's ... both of those have 2 V-6's to form their
V-12 ... also rumors of a V-12 for the Excursion when it comes out ...

Ford developed a V-12 about 2 or 3 years ago for the concept car Indigo. It
was an open top roadster to go head to head with the Prowler. I would have
loved to have seen this car go into production, maybe even conned a dealer
into a test drive also VW made a V-12 by splicing together 2 of their
