I had a low deck M1 TR on my little 451 in my DartSport with Eddy heads and 590 purpleshaft cam. I ordered custom tunnel ram 750's from Quickfuel, car weighed 3050# and ran a best of 9.89 at 136.
Carbs were spot-on right out of the box and they had a wedge-shaped fuel bowl floats that were supposedly good for tunnel rams if I remember correctly. These days I wouldn't hesitate to order carbs from Dom.
