73 340 and the Thermoquad

Picked up a nice complete 340 today along with the matching 727 trans.

It has its original iron spreadbore intake and I’m wondering if the original intake is a decent piece. I dont need to squeeze every last horsepower out of the motor but I don’t want to use it if its gonna rob me of 25 hp versus a newer aluminum design.

On the carb, I’ve limited knowledge of the Thermoquad but I know lots of Mopar guys love them. Are they difficult to rebuild?
