If you truly want a reliable engine and you're building it file fit the rings put good bearings in it don't buy the cheap crap don't use cast rings and make sure if the pistons are used the ring lands are clean, clean all the water passages and make sure valve guides are on the loose side of tolerance that is the biggest issue I have ever had and I set the fuel mixture a little rich and timing between 28 and 34 degrees depending on the cam at 3000 rpms and people can say what they want I run with 2 other guys 1 runs ford 1 runs sbm and I run sbc they all get hot about the same time running looped hoses it comes down to who lets off the pedal first

I do on some engines and others I don't, but I prefer vacuum advance to be hooked up

Timing and fuel makes a huge difference A number of people say "timing and fuel", It is my understanding that advance timing runs hotter but better performance and retarding the timing when it's hot makes for easier starts. Please people elaborate on both timing and fuel. What does fuel have to do with a cool running engine, doesn't it create the heat?

Fuel plays a big part in controlling temps. Touch the intake of a ln engine running on alcohol once, you'll understand when you feel that it's cold.

Well sure alcohol, thats like having a second cooling system. I raced with IMCA guys that don't even have radiators, but many derby shows out here don't allow it. Any other fuel timing tricks any wanna whisper here ?

Fuel and tuning is all based on the build of the engine. Different build types get tuned differently. You understand that. So, give us some details on your build Amd we can help.

I think the biggest part of keeping an engine running after u lost the radiator is quality parts. Yes timing is a extremely important. but,Once you have lost all your coolant your engine will get hot. There is no way around that. But with quality internals that are installed properly, these engines can put up with allot of abuse. And I'm sure that there are tricks like running loose tolerances that the top engine builders have found that make them last even longer. But they have spent the money on quality parts to use these tricks on and that is why their engines are so reliable.

For me, I think a good part of the equation is also the rest of your drive terrain. Easier gearing helps to not street the engine but is also a catch 22 in allowing It to rev faster=heat. When I get pick up an engine I also ways start out by getting new oil pump, Gasket set, and double roller timing chain. 200 dollars later you have a 500 dollar small block that is reliable. Now timing and tuning is where everyone has different opinions. I have been told by a reputable engine builder that setting what I have(268 cam), power pack heads, and 2g carb to set my timing at 12-14 degrees advanced and no vaccum advance. Total timing of 32 degrees. Now most will say set it to zero and when it's hot it will crank..... that maybe so but if your firing at tdc it will not be a powerful detonation in my opinion. I may be wrong and willing to learn and listen. Also investing in 1:1 pulley set up or a better than stock water pump is also a good investment. Radiators and radiator choices are also valuable. I only run four core radiators with a steel 9 blade water pump fan that i shroud with cardboard. Others like electric fans on aluminum radiator. Thermostat choices also factor in your flow. Not enough flow, and your over heating, to much flow and your not cooling.
Again thus entire post I could be completely wrong but just going off what I have been learning through the years.
