Then what are you doing over here discussing FE engines? 
My builder (here in sunny Houston) and the dyno guy (both with lots of FE experience) told me to run either 10W-40 or straight 40W racing oil with a high zinc content for my flat tappet/solid lifter FE. I am running a blueprinted Melling 57HV pump and get the idle and running pressures noted above, and my bearing and rod side clearances were in spec. My pressures and temps are very predictable in relation to one another.
If the OP Jon (saltshaker) comes back maybe he can tell us what weight oil he is running because a heavier viscosity oil will run a bit hotter. |
