Nice racing. Are you saying the the combustion temps. are that much cooler with the reverse cooling?
My L98 tolerates 11.02 SCR and 225lbs. cranking compression fine. I do have the cooling system optimized though and use Champion #6 racing plugs.


The cyl head itself is actually cooler and it transfers heat much more efficiently because of the reverse cooling. A good portion of the engine temp is generated and tranfered in the combustion chamber.

A lot of Comp and Stock Eliminator guys run their water temps down around 140*F to make the most HP. I know there was a big deal a few weeks ago on an engine builders board about Joe Sherman dynoing a customers engine at that low water temp but I was like... darn I thought everybdy knew about doing it.

Anyway if you keep the cyl head temp down (amound many other things) you can get away with it and it really dosen't matter what kind of engine. It's just that the LTX was specifically desgined to take advantage of this kind of thing.
