Jhein, don't be so quick to scoff at the Super Duty T/A's. Those engines were phenomenal performers - even moreso because they produced good numbers when all the other muscle cars had gone the way of the dinosaurs. They were rated at 310 and 290 HP in '73 and '74 respectively, but those were conservative Net figures as opposed to the overly optimistic gross ratings used before. I too was a big fan of the RA IV (and don't even get me started on the legendary RA V) but the 73/74 SD was superior. I lusted after the 74 model for years and finally bought a regular '74 455 automatic in 1978. I did a lot of tuning and tweaking with that motor trying to pretend it was a REAL Super Duty and my best time on N50X15 Formula 1 Super Stocks was 13.2. That motor was a brutal, monstrous beast down low but was eternally plagued by valvetrain problems at even moderately high rpm's. I really should be arrested for the amount of tire smoke I put into the atmosphere with that thing. Still dream about it sometimes.
