Well I think Im satisfied with the information I have recieved and will remain with the 4-53T as recommended. I guess a little more surching to find the turbo. The dont think the seller posted the if its a 6xx or 66xx on the trans. I would have to check again. Grigg I saw your you tube post of the 61 ford doing a pull competition. Guess you just wanted to see what it would do. Ill post when I find a 4-53T and I think I will call the guy with the trans you told me about: The one with man who would not reduce the price.
