If not try it, it was around $200.00 more for the T&D when I bought mine for my SR heads three years ago I think the SR use the same rocker asemblys as the stock 383-440 motors do Call Summit and see what they tell you on prices and drop shipping them direct from Harland Sharp to you and delivery time

Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
