Thanx in advance for all the help you guys can offer.

Haven't worked on one of these, but I would think there should be an adjustment
where the throttle cable (outside) is fastened to the TB. You should be able to
loosen something and slide the cable away from the butterfly opening lever and
refasten it down. This will give you more length of pull, therefore more
opening of the TB.
Hope this helps.

Subject: FTE Perf - Drilling holes in T'stats

As most of you know, I work for DaimlerChrysler and am about to retire.
Chrysler has recommended this drilling holes in the T'stat procedure ever since
it produced the 1st Aluminum head or block. It helps to keep an airlock from
developing at the T'stat and getting the head so hot prior to the T'stat
opening, that a head will crack.
It works very well also. The size of the hole should vary depending on the
displacement, though I think.

Hey Azie comes through for us again! Are we gonna have to an FTE style
retirement party ?

Anyway, I was wondering how you based it on size ??? Larger for more
displacement, but can you give us an idea how large is large ?

Thanks,

The Stewart info says three 3/16" holes but he specializes in 358ci
NASCAR engines producing 750HP at 8000+rpm. I'm going to try it but
can't decide on the size of the initial hole. As draining part of the
coolant, removing half my distributor and changing the t-stat several
times with cooling off time isn't my idea of a fun weekend, I'd also
appreciate any best guesses or experience with the 460.

Sounds like maybe something slipped either where the cableattaches to the
throttlebody(should be a snap thing isn't it ?) or maybe wherethe pedal
attaches, is there a way the sheathing got moved, it sounds likethe cover
is too long all of a sudden ...
Just my 2centswish


There is a snap that holds the throttle cable in place on a bracket on the
upper intake. It's possible the sheathing has moved...
Has anyone replaced their throttle cable on a similiar truck? Is it a
difficult job? any idea how much it will cost me at Ford? thanks again.

Its possible that has moved, I think its also possible to put the plate on
rotated a bit too, maybe you got it on a little cockeyed that causes it to
not mount right ? Something to check into, also check those little clips,
its possible that the whole cable is moving (including the sheath instead
of just the cable) ...

No clue why you want to do so, but here's my thoughts.

Obviously have to do away with the in tank pump and go to an older tank
unit with no pump as 40+ PSI will trash a carb ASAP. FP regulators wont
take this high of a pressure for long either so that's not an option.
Next question is if you want to retain any computer controls; if so then
get a carb'd model wiring harness and computer.. if not then you need to
change the distributor and all (selected) emission controls to 1980 or
older specs. I'll trade my '79 LTD 302 stuff for yours! (Variable
Venturi carb though.. you would be a fool to take it! )


> Stuff
> like fuel pressure and wiring is the major question.

Fuel pressure is the biggest. A must is to ditch the in tank pump for
an older style unit or yank the pump and use straight hose and an
electric pump elsewhere. Another option after ditching the electric
might be to use an older timing cover and eccentric to dive the older
style mechanical pump. Wiring depends on the system you want.

> Would a dura spark
> module plug in?

No. Easy enough to rewire for one or a 'so called' high performance
unit though.

Better to hop up the existing EFI but if you MUST modify it so, then
have fun. ;-)

As is Jagermeister.. Hmm.. BRB I think there's some in the freezer for
long posting nights.. Yep.. guess this will be my last post for the
night else I'll get hammered and post until it's time for work!


How deep were the cracks? I'd base my worrying on that.. little tiny
surface cracks I'd ignore, but major cracks I'd think about.

I wouldn't myself. Basically you're increasing the bypass vcolume
designed into the vehicle. If it's for hi-po use then what the Hell..
go for it it'll have a lower temp at the CTS causing a richer mixture.

........

It seems difficult to tell just how deep the cracks go below the surface
of the flywheel or pressure plate. I'd much rather play it safe, than to
risk a catastrophic failure. Has anyone had a flywheel scatter at high
RPM's? How much better is a "Lakewood Blowproof Bellhousing" than a stock
FoMoCo housing?
