I have tested MR Gasket Balanced HP thermostat 180 (4364) and it works but it is not a classic style and has a rubber gasket inside but you cant seeing it. I have also tested Tuff Stuff Performance SuperCool High flow 180 thermostats (900180) and it worked great in our 428 engines with 2,12in, 54mm size. Se picture for different openings related to an old one in water. Erik

That's the style I used. Seems to give a better flow rate than the factory design.  I used a 160 degree.

Lost the thread this was discussed in the crash, just confirming this is the T-Stat we discussed;

It looks like the same design . I think there is one MFG and they private label for Mr Gasket and others

160 is too low for optimum power and minimum wear.

ha ha. wave a red flag, ya gotta expect the bull to attend the party.

I feel actual physical pain and mental anguish when I visualize that thermostat poppin' open @ 160.  But hey, if someone thinks they know better than the engineers that designed and built these cars, then who am I to try and yank their head out of the sand ?

when you live on the left coast and it is 110 degrees or better all summer long the angry hot big blocks love the T stat to open at 160 and while driving they usually settle in around 190-200 for optimum performance. Just some personal experiences from the left side.

+1 . Just because it open's early doesn't mean it will stay at that temperature.

+2. Mine runs between 195 and 210 on the right coast.

of course not. But any extra time an engine operates below the optimal temperature range subjects the engine to increased wear.

It's well documented that a great percentage of wear does occur during start up and before the engine reaches full operating temps. Deliberately extending this "cold" period by using a early opening thermostat is nonsensical.

I think we understand the law of averages that the auto manufacturers needed an AVERAGE temp T stat for cars shipped all over the world. 180 seemed to be the number- Since temps are wildly different in various parts of the world different heat ranges of T stats are available from 160-200 that's just when they open not where the engine operates at. You could write a book on variables from RPMS,LOADS,HORSEPOWER,FRONTAL SURFACE AREA,SPEEDS ETC. The common guy driving his common car,presumably stock 302-428 to the grocery store or local shows or whatever need not cringe when his T stat opens at 160 it will settle in to its 180+ range if not, a simple change to a different heat range will fix this problem typically in colder climants. :)

Well, 180 was NOT the number that the Ford engineers were thinking of in 1966 across the entire V-8 range of engines, small blocks, and the  big blocks that were going into the full size Fords too.  They wanted the operating temperature  to be 190 minimum, and 200 - 212 was optimum.

Am still looking for my '67/'68 shop manual, so can't say for sure, . But I do know for certain that  '65/'66/'67 HiPo and the  & C code 289's, as well as the big block engines going in the full size cars in 1966, did not come from the factory with a 180 degree thermostat. They  came with 190 / 192  thermostats. Those don't even fully oven until the engine is 210 - 212 degrees F.

I'm always amazed at the number of people who think 210 - 212 degrees is overheating.....
