My friend runs that intake on his 65 Plymouth. 650 Eddys,.557 Mopar solid, bowl jobbed 906, small headers,4.56 It runs 11.50@114. Very consistant. Basicly a street car no cage,subframe connectors,electric water pump. We have never run any other intake though we did try 750 Eddys which were no help. Never changed the stock jetting. We have open spacers under the carbs and the stock Hemi style scoop is sealed to the hood. We used the stock throttle cable.
