Can't say for sure re. the Torker inlet on a small block on a big block its certainly regarded as a non-performance item. The name Torker itself is a major misnomer as it doesn't add torque to the engine, except perhaps at higher rpm (where its not required) - I used a Torker 11, along with a Holley 750 double pumper as the first upgrade on my original 427. It certainly didn't produce any addition power over 4000 rpm, but did make the engine more responsive between 2000 and 2500 rpm.
You've already indicated that the 3.07 rear end is probably too much of a ratio for off the line performance.........a dual plane inlet would theoretically improve low end 'out of the hole' performance.......but would possibly be higher than the Torker, creating clearance issues.
