390 cfm 4 barrel with short boosters We
found a couple of classes across the country that specify a 390

650 HP GAS Based on the Holley® #80541-1 Designed

DIRT 650 Based on the Holley® #4777 Designed
to meet the rules and gauges of the DIRT circuit in New York and Canada
- whatever they may be for this point in time - after having this rule
for about 10 years, they seem to keep finding new ways to tech and
alter the rules especially in Canada. Could it be the Canadian car
builders want everybody on crate motors and stock carburetors so that
they can spend more money on chassis and suspension parts?
