I have looked at my latest small block project and decided to delete the factory bypass hose and run a smaller diameter hose from inlet manifold to radiator it would be through 3/8 npt to 8an fittings and hose, i still run the thermostat but will have all water going through the radiator instead of having a small amount bypassing. As it's a new build i can't say if or what temp it may run at but I'm sure it should run cool even without what i plan on doing with the bypass, i was just looking for any input as i may be overlooking something, and yes I'm aware that it probably won't be flowing much once the stat opens up however im from a pretty hot climate so any little help with cooling can't be a bad thing, just thinking outside the box, worth it or not.
