cfm's? want to know what came stock on the 400 cubic inch trans am in 1975. i have the car and want to get a new carb but not sure how many cfm's i will need. thanks
 
Something around 650 cfm's should work ok for a stock engine...spread bore---depending on the intake--- and vacuum secondaries for better economy.
