1973 340 detuned?
keep in mind,,NOT ALLL but a good percentage of 1973 340s were cast crank,,externally balanced,,requiring the correct torque convertor,,or fly wheel if you have a stick shift,,,this will effect what rods and pistons you change,, a 73 340 with a good intake,,,cam and exhaust will run great in an A body,,,and wont require high octane gas,,,they run great,,
