RE: 352/390 exhaust question |

blocking the heat crossover on a medium or low performance engine will definitely cause a power loss. the intake charge is too cool to keep the fuel properly atomized and so it is puddleing and running to the back cylinders. i'll bet if you pull the plugs and compare them they will be different colors front to rear because of poor mixture. you should only block the heat crossover when you have the cam and exhaust to create strong vacuum due to good flow and valve overlap. hawkrod |
