Ran a Wieand TR & 600 1850s on a 451, low-end torque was no problem with 4.11s, 4100 flash stall (tons of it) & the top-end power was in a class all its own , this set-up was more streetable then my single 750 & M1, Don't listen to what some tell you about TRs , if they have nothing good to say about them, its because they NEVER ran one or they had the wrong carbs & don't know what there talking about , simple as that
