I've heard many times on this board that "These engines were made/built to run HOT".

This being said, if that's true, then what about a motor that one would build? Are we talking about specific F-Body motors are made to run HOT or are we talking 305/350 TPI/TBI/CFI/4BBL V8's are meant to run hot?

If that makes sense.

Basically, if I build a motor and want MAX temp to be at 200-210 or so normally, am I going to be able to achieve it or is the body/design of the 3rdGen not suited to those low temps? I've got a '93 Beretta GTZ w/Quad4 HO/W41 and I _never_ see temps above 190 on the gauge when I'm moving. Then again, it doesn't depend on an air dam for air flow over the radiator.

 

my experience (3 350 tpi thirdgen's) is that thirdgen's were made to run warm. 195 stats being used. so i simply went to a 180 stat and that cooled the engine down some, and thats with stock pump, radiator, etc..


with a 180 stat, proper air dam, and proper fan switch you should be able to keep to stay under the range of temps listed.

 

these vehicals and just about every other vehical out there are meant to run as hot as possible. reason being it lowers emissions and runs better.. (not performance wise however..) 180-195 is the thermostat of choice for most manufacturers.. there are a few cars (mostly imports) that require lower temp thermostats,

 

I am experiencing the problem right now. I switched out my 305 for a 350, With the stock cooling equipment it wants to get up to about 220 and continue climbing. I just did an overhaul to the engine, and I was told that moly rings just get hot when they are wanting to seat. I was also told that with new engine parts it just runs hot. I was told that my compression being higher,(10.5 to 1) is also going to make it run hotter. I got a 160 stat, stock radiator, a hp water pump, and my fan ran through a toggle switch for more control. I turn on the fan at 180, but my temp still climbes very high. Can someone help me please?

 

im having a simular problem i have a 305 with elder block intake manifold.....
but it takes it a while to get passed 220 but its just the fact i dnt like and it getting that high...i put a bigger radiator with 180 thermostat and the water pump is working good....so i dnt know wat else 2 do...help please!

 

Well check you coolent pressure maby you have a leak being a newly assembled motor its possable even a head gasket if it wasnt done right. Check to make sure the air dam and fan shrowd is in place and you may have to upgrade the fans to a dual electric fan set up or a upgraded radiator.
