Thanks guys,

some other folks here 'bouts have said the same thing about the power
valve... since I am gonna rebuild the carb anyway, will switch out the
power valve... go to a "65" and try that...

When I got the carb, the previous owner had put a 36 squirter
(accelerator pump discharge nozzle) and the lightest yellow short
spring made in the secondaries vacuum control... he said he had a very
aggressive cam in a heavy car (ranchero) running a 302. I have since
changed the spring to the standard one and changed the squirter to a 31
he sent in the package... thinking of going to a 28 but not sure...

Thanks again...

Wow, he thought the Ranchero was a heavy car ? Wonder what he thinks of
full size pickups then ? Ours has the 600 on it and is just bolted on as
far as I can tell (no sign that anyone's tinkered with it) ... that little
Vtech Honda last weekend didn't have any idea what hit it when the light
went green ...

Hopefully you can get things squared away in with the rebuild ...

Shane, check all the easy stuff first. Fluid level AND smell, Vacuum
modulator, Adjust bands. On the C-4 the Intermediate band & Forward
clutch pack are used in 2nd. gear. If none of these things help, you may
have a clutch pack starting to fail. ( not at all uncommon ) There's
several other things it could be also. But way too lengthy to list here.
Look in a trans service manual for a trouble shooting list. Bottom
line.....if the fluid smells burnt and the trans has had a hard life, and
a lot of miles, pull it and go thru it. Add a good cooler to it on the
re-install.
I don't know if your interested or not, but IF you ever wanted to try a
trans overhaul, the C-4 is a nice one to do. Not too big, nor overly
complicated, and very easy to get parts for. And since it appears you
race it some; throw in a good shift kit. You won't believe how hard one
of those things CAN shift !
Hope this helps, Phil ( 64 F-100 w/ C-4, 66 Mustang w/
B&M C-4)

Thanks Phil,

I had the tranny rebuilt last year but I had it done
by one of those cheapy places, $169.00 out the door,
you know the story. The same thing happened in my
Pinto. Went through two C4's at the cheapy places
before having one "built". The extra money was worth
it. Raced three seasons on it and had no trouble
whatsoever. It shifted very hard... Auto trannies
are the only part of a car that intimidates me. I can
do everything else but that. I have the biggest B&M
cooler that I could find. I guess I'll consult my
Motor's manual to adjust the bands, change the fluid
and modulator and see what happens....

I want to get this fixed because I have a free night
coming up that just happens to be racing night. I've
re-jetted my carb and made a few other ignition
adjustments and I want to see if I can squeak a 15.25
out of her but I just don't trust the trans.

Where could I get a rebuild kit for it if I wanted to
do it myself?

probably needs rebuilding... normal acceleration with just a little
throtle is smooth, acceleration under full throttle is strong and
smooth, but partial throttle, like just before you bring the
secondaries in or engage the tranny kickdown is "surgy" (if that is a
word).. not really a miss, but like a series of stumbles during the
acceleration (not the same kind of stumble like secondaries coming in

I know you weren't talking to me, but I read it anyway. My guess is you need a
new/different power valve. Older model Holley power valves give some problems,
and this is one of the symptoms.

Anyone have any input on using the Motorsport camshaft p/n FOR-M-6250-A341
for the 335 series motors (351C/M/400)? It looks like it has some pretty
good numbers, comparable to the cam used in the 400 build up in Hot Rod.
Duration: 292 deg (214 .050) int., 302 deg (224 .050) exh. Lift .510" int.,

Subject: FTE Perf - 2.3liter bracket racer

I don't know if there are in fellow 4cylinder racers reading this list, but
if there are maybe you could give some help. I'm building a 58F100
with a 460 for street/strip-emphasis on the strip. With my budgeting
dollars and time, it will be a few years before its completed. In the
meantime I'm putting together my 92Ranger 5-speed manual for bracket
racing. So far all my bracket racing experience has been of the fantasy
kind.
But tonight I went over to Sears Point planning to participate in the weekly
Wed night bracket racing. Unfortunately there was no racing tonight as
they're getting ready for this coming weekends NASCAR event. My plan
is that the Ranger will let me learn the basics on the strip without being
distracted by a superfast truck--its not believe me. My practicing here and
there on my marked off country roads look like I can expect about 22sec in
the 1/4. Obviously I'll be competing for consistancy not speed. Has anyone
found any good speed accessories useable here is the Republic of
California for the 2.3L? Cat back exhaust? Do they help? K&N filters?
Has anyone hooked up a "shift lite" type tachometer to one of these computer
controlled cars?
Appreciate any help.
Sorry I was soooo wordy.

May have a little too much duration for use on the street......

You may be better served getting a cam closer to what
the boy's at HR used.

Subject: Re: FTE Perf - Motorsport camshaft

It's interesting tho' I was talking to a guy that's been building Fords for
a lot of years, mostly FEs, and he told me something that I've never heard
before, that the big (Comp, Crane, Edelbrock, etc.) cam makers use Ch*vy
small block grinds as the basis for all of their cams and simply make
changes to fit the other makes specs so most aftermarket cams run like a
Ch*vy small block cam in a Ford which is to say not terrific. So I'm
thinking (always dangerous!) well now maybe Ford can do a better job of
making a camshaft for a Ford motor, so maybe a little more duration is just
what my 400 needs to run real stout even if I can't get the comp ratio up
where I'd like it. The specs in the catalog say that this is a "good all
around performance" cam. Hey Muel you out there?

The cams listed in the FMS catalog are made by one of those "Big" names.
As a side note, Engle has some nice profiles, and I've heard good things
about Crower.
