I have 5 cars with three on the tree, my truck has a 4 speed trans now just had it installed 4 days ago. I must say after I got used to shifting on the floor I enjoy the driving ease. coming to a complete stop is dangerous you know how crazy regular people drive. A 4 speed trans puts you in front of the traffic. You need the other things to go along with it. I have had these thjings installed over time.You need the 3:55 gear in the rear,dual exhast, dual carbs and a nice howard cam. I have these things and enjoy my truck to the max.
