High engine temps!

Cylinder temps seem to be the cause of most over heating! Burning all and leaving a cooler black hole of vacuum to pull the piston up before a bit of compression takes place, can run cooler! Burning with twice the fuel dumped in of a lower octane with lower compression, power is achieved! Lower temps can let vacuum cause the refrigeration process of fuels to improve flow and volume factors of carbs, intakes,and heads! Creating a vacuum draw at the end of your burn cycle is the best way I know to build torque in a low compression engine! A .066 350 that runs at 150 degrees and burns nearly twice the fuel cleanly has to be putting it to good use when wining! It does require every cooling trick to get there but it's still the easiest horsepower I know! No expansion before hand leaves more for the big bang! Never think of your engine as weak but as miss understood in some ways placed in the mix of technology! Cooler fuels makes more horses, cooler engines do also by keeping it cool until the power stroke! More timing in cams, geometry, and ign. to make up for getting it burning to match stroke timing will be needed to increase vacuum and torque!
