Replaced the quadrajet on the 77 because the fuel would boil out after shutdown. The new 800 cfm Edelbrock was no better and worse hot starts. If I let it idle for a couple minutes during hot weather it`s better. The temp guage reads 180 consistently. Fuel injection suffers none of these problems due to the high pressure. Case in point, look at the vapor lock problems in air cooled engines in hot weather.
