So on my 70 Duster, from what I've found out, has the engine and drivetrain (360/727/ 8 3/4" rear end) out of a 74 Duster. I currently have an older Holley 750 double pumper carb & LD340 Edelbrock dual plane intake on the motor. What little I was able to drive it before I put it up, the carb seemed to be doing well with no hesitation, stumbling, or any other quirks. I was thinking that it would be fitting to find a 74 Thermoquad to put back on it for nostalgia and overall Moparness. Truth be told I've never been a fan of Holley carbs on Mopar engines anyway. Would it be worth switching? or "If it aint broke don't fix it"
