I hope that carb works out for you but would like you to know my experience with trying to install that carb on my 71 Demon 340. My original TQ was leaking gas into the intake and the adjustment sequence seemed intimidating to me with no experience in tuning carbs so I opted for a Street Demon 625 from Jegs. The geometry of the carb linkage simply is not compatible with the stock accelerator cable and kick down linkage on a 340 even with the Mopar stud installed. I sent pictures and requested tech help from Demon carbs and they had no answer. It seems to me that they did no engineering work to make these carbs work with stock Mopar linkage. I do not know why they can"t engineer some kind of adapter kit like Edelbrock has for their carbs. Disappointed I sent the Demon carb back to Jegs and they were very cooperative in giving me a refund. I had the TQ rebuilt and now the car runs very well and I am satisfied.
