I used to have a 393 using a F9 roller block. I'm now using a D4 block.
Nitto 555R tires
I have never used a TKO, T5 is quite efficient, I hear the T5 shifts better
T5 goes in easy but touches the transmission tunnel on a 65 not an issue on a 69
I have a 69 Mach 1 and I was wondering what 351 W block did you use for your build and how much torque does your engine produce? Do you run street drag radials? How efficient is the transmission and how it compare to a TKO 600? Did you have any problems installing the transmission in your car? I am about a year a way from doing the same thing to my car and trying decide to do about the engine. I want engine to produce 450 HP and Torque at the flywheel, so every thing will have to be efficient as possible.
