Have you thought about a Thermoquad carb? I use a chokeless 850cfm TQ carb on my built 340 Duster. The difference in the topend is fantastic compared to a 600-650cfm carb.


1970 FE5 Duster 360/904/3.91's SOLD 1973 TB3 SpaceDuster 340/4spd/4.10's SOLD Moparless for now but when the opportunity is right I'll have another one.
