gday, i want to go straight lpg on my 253, i have a four barrell manifold that can take either a holley or quaddy throttle body. does anyone know which throttle body works best with the impco 425? and is the 425 too much CFM for a 253? or should i be looking at a 225 instead? i have a mild lpg cam and performance manifold but the rest is stock.
