you control the heat. I used 2 chev heater cores back to back under the
front valance, also a louvered hood plus 2 x 3'' exits in the upper fenders.
Runs nice on the highway. waiting for a stage 2 water pump which I hope will
do the job. Any suggestions will be appreciated.

Chuck,
        My 351C (4 barrel quinch heads from 70 Torino) runs a lot cooler
than my original 289.  I commute in Florida traffic every day for 35
minutes with sometimes a good 15 minutes in real stop and no-go traffic.
No overheating problems at all. Maximum usually runs at 90 degree C.
Actually runs slightly hotter at constant 85 MPH in 95 degree air.
I also burn 11 to 13 MPG in town and 17 or so at 85 MPH.
I did a lot of mods under the hood.  Moved (replaced)the firewall 6" back.
Replaced the frames with 2X3 steel tubes (immediatly outside the old frames).
Adjusted the inner fenderwells to match the new frames.  
Home made 1 5/8" tubing headers with Thermo-Wrap on them.(The Thermo Rap did not
help in the overheating department.  I put it on there to keep from damaging
the upper A arm bushings.  Now I have a sheet metal heat shield for that
purpose.
Radiator core now 23" wide using ordinary late model 2" thick replacement core
material. (Remember the wider frames?) Fan is 5 bladed about 14" from Sears 
196x Rambler add on air-conditioner kit.
 Modified the original Tiger fan schroud
to fit width and later I added a full 360 degree attachment. Moved the motor
back
1 1/4" so I had to add a 1" spacer between the waterpump and the fan to allow
the rear edge of the fan to extend past the fan schroud.  There is around 1 1/2"
between the fan and the radiator core with the spacer added.  Have a reversed 
hood scoop that was mainly to clear a 3" core air filter.  Below 35 mph air 
exits at the rear of the hood. Above 35 mph the air enters at this point.  
Did not block off the areas around the horns.  
Previously had an air dam that extended from the lip behind the
bumper down to within 3" of the ground.  Had rounded openings to allow air
to get to the
stock TigerII oil cooler.  This dropped the temperature a good 15 degrees when
running.  However it wore out and I no longer have the Air dam.  Was made of
a sheet of
3/8" plastic.  This air dam also had a major impact on stability.  No more
"floating" 
above 130 mph, solid as if I were doing 55 Mph.
Use a stock later model Ford magnetic pickup distributor and a stock Ford (cheap
aftermarket copy) ignition module.
Have a 195 degree thermostat as the motor runs better when warm.
Have an Edelbrock 4 barrel Cleveland intake and a 650 Holly double pumper.
Manual choke, that is needed for until temp is up to 80 degrees C.
Also have a cheap aftermarket 14 lb radiator cap and an overflow plastic
container.  Still have the expansion tank which is kept completely  full
with the
overflow setup. Stock Cleveland waterpump with stock tiger pully on it.

Previously had a Boss 302 in the Tiger with no fender/firewall/radiator mods.
It overheated bad in traffic.  Attempted to solve the problem by adding a
araiator in the trunk.  Hole in floor of trunk and a ducted boxed fan
via another floor hole. Ran that radiator off of the heater hose ports
of the waterpump.  Helped some but mostly added unberable heat in to the
drivers compartment.
