Technically, as long as the water is in contact with the block heat transfer is
happening at the same rate regardless of water speed but the speed causes
more turbulance and I think it's the turbulance that causes the problem not
speed by itself. Technically, more speed means more cooling......IF the
radiator can dispose of it. Put a big enough radiator on it, take out the
thermostat and run enough volume past the surfaces in the engine and it will
run COLD not hot from a phisics stand point but as you said the turbulance
causes areas where there are lots of restrictions and turns to actually cavitate
which is what is the real culprit IMHO.

Heat moves from the block to the coolant at the same speed or rate no
matter what based on only two things I know of: Temp difference between
the two mediums and time. If the water moves too slowly the temp differnce
will diminish causing a loss in efficiency but if the coolant is separated from
the walls for an instant here and there then the time eliment is compromised
which is what turbulance does.

I'm sure most OEM cooling systems are perfected through trial and error
based on these phenomena. Run it too fast and you get good transfer but
may cavitate some areas of the heads causing hot spots and "after boil" on
shut down etc.. Run it too slow and you will have even cooling but may not
be enough transfer to keep the engine cool enough.

Put cement in the block and who knnows.......?? :-) What's the cement for
again?

seen the chevvy ones advertised. saw the article for the fords.
question...how much power increse was the cam, and how much the heads? it
has really small valves in it. it also has some custom parts like exhaust
rocker. small ports for high velocity. these heads will not rev well.
too high a velocity. but, this is what makes them work supposably from
idle up to maybe 5,000 rpms.

noticed also that the exhaust valve/spring will be sitting in oil. it will
stay cool, but it will also use oil unless the valve has a teflon seal.

i don't know the price, but IMHO the same cost put into stock heads and
parts will do just as much, if not more. just my opinion. would like to
see a set in person.

Has anyone else seen the Nov98 aritcle in Popular Hot Rodding about the
soon to be released Feuling alumuinum big-block Ford heads? I'm not
familiar with this manufacturer, but according to the article, the magazine
did a piece some time in the past on Feuling alum heads for Chevys. I'm
a long ways from being an engine techie, and I thought if anyone has had
experience or knowlege about these heads maybe they can share the
wealth. The article shows the heads combustion chambers to be a kind of
figure-eight shape? The Ford heads are still in testing, but they give
numbers
like their bench mark 460 before the heads has 465lbs/ft torque at 2,500rpm
and 274hp at 4,000rpm, and after the Feuling heads plus a cam change they
get524lbs/ft torque at 2,750rpm and 369 hp at 4,250. The article doesn't
hint
at prices, but they plan to market the heads for street performance, boat
builders,
and "sluggish tow vehicles".

to keep the very thin cylinder walls stable. they are still too thin, but
enough for now. i'll get a better block ASAIC.

when overboring the concrete is needed, for the 460 at anything over .060
is not recommended, but at .090 cement is required most often. at .110
like mine, most blocks the boring bar breaks right into the water jacket.
basically with cement, a 4.470 bore is max on a stock 460 block. the svo
block will take 4.500 with no concrete - that's what i need, then it will
stay cool.

concrete can also be used in small amounts at bottom of water jacket to
help stabalize thicker walls too, and then gives a side effect of keeping
oil temps higher and coolant can be run cooler, and that makes power!

oooh, i want that AR boss! wonder if i could hide that from the tech guys?
no, didn't think i could, but it would look real nice stuffed into a 56
effy!

i had the kicker shocks on my 77 f150 (460/c6/3.54/33") and found they
didn't do sh*t. they worked as long as i didn't give it much throttle. i
do agree about the ladder bars completely though.
i ended up building a rancho type bar (before rancho was selling them
AFAIK)
no suspension travel limiting (ok,ok, just a bery little bit) and worked
off road, hard launching on the street (actually launched perfect, like a
pro stocker without the front wheels lifting) and for pulling.

i also thought of using a verticle bar, and linear bearing to stop axle
wrap, and no suspension travel limit, but for what i did most, the bars
work best.

maybe if i used double rancho 9000's on full hard for kicker shocks it
would have helped? don't know, but i have a dislike for them kicker
shocks. but i am sure that they work for you. i have no problem with
that...

if intereseted in the way i built my bars, let me know.

Were I to think about a "Boss"
there is a Intercooled, Twin Turbo, DEFI, 634 Inch AR BOSS Engine in the
shop and it is the one to use. As soon as I figure out how AND have the
time
I do intend to scan the pictures. EYE CANDY! All Aluminum and stainless and
polished to with in an inch of its life! Try 2000HP!

big snippage----------

I still had moderate Wheel Hop both under power and breaking. My solution
was Dual "Kicker Shocks" on a custom designed set of brackets. Ladder Bars
are simply a joke for anything that turns, or crosses rough ground. They
work on Drag Racers and I have seen them in action on some pullers (though
I
am out of my league here, SD?). IMNSHO Ladder bars have no place on a real
4X4.
Nufffffffernow!

Due to the geometry and forces involved here I'd say kicker shocks would
have to be VERY heavy duty and have excessive amounts of compression
damping so regular shocks wouldn't work since they have little compression
damping. Steering dampers may be the best choice but they are not strong
enough to resist the torque you will apply in a launch IMHO :-)
