Same here without problem!

the block itself should have nothing to do with the oil temp.can you give us more info on the new build.

OOOps. Doh ! I was just speaking directly on what I quoted you .
I agree with you, a 50*F difference I would doubt.nothing is different than just the block. Tighter clearances can increase it some. Tuning can change it some, Etc, etc. |

Tune plays a huge role also, My builds on year one I would see 200-220, with a much safer tune I saw no more then 150....with absolutely no other changes....now that being said I prefer 190-220 temps, more heat = Power....

180 is probably the coolest oil should get 210 is what it is tested at for viscosity. Keep it under 300. Ken |

Way too cold for oil, You probably increase you oil level in your sump because you dont burn off the water from condensation.

My theory is this. Heat kills parts. So why if we are using oil to cool the parts inside the motor would you use hot oil to do? If the valve springs make 75% of the heat in the motor and heat kills the spring don't you want to try to keep them cool? It's no mystery 170 is the optimum number for making power. And this is due to fuel vaporizing on the cylinder walls. So how do you maximize the power potential but make the parts in the motor last? I would think get the temperature up in the block but keep the oil on the cool side to keep the parts inside cooled down would be the answer. Right or wrong that's what I'm trying to see what happens. If it's wrong I'll go the other direction with things. So far what I've seen its the right way to go about it.
