It's official!!!
We have contracted with an Australian manufacture to provide us the correct Hi-Flo thermostat for the 351C/351M/400 engines.
BONUS...we are getting these made in (3) different ranges. 160, 180 & 195.
***Track Boss Products will be the only supplier of a Hi-Flo Cleveland thermostat in the world, that has all 3 temp ranges***
*Please remember 351M/400 do not need the by-pass restrictor.*
We "should" see inventory within 1-2 months...

 

Excellent! As said on FaceBook, I want one - 195 degree, please.

And, feel free to use my engine as a test mule to see if there's any difference in temp with a hat-style 'stat vs one w/o the hat. However, I don't know how big your cooling system for the dyno is, so that may not be a valid test since a huge cooling system will probably not show any difference.

Also, when you get the product up on your web site please post a link here as I want to include that link on my web page here: 351M/400 Thermostats - ???Gary's Garagemahal

 

I know it's too late but a 185 would have been a good temp choice.

 

Ford never offered a t/stat for 351C/351M/400 less than 192 degrees.

MAINER FORD in Okarche OK has 1 = 405-263-7242.

CARPENTER NOS OBSOLETE PARTS in Concord NC has 9 = 800-476-9653 (as D0AZ)

 

I understand Number Dummy but Ford never dreamed of the mods I've done.
