C-4 tranny question

[FastFox89]

Hows it going, I just recently built a 347 and was looking into various C-4 tranny's. I just wanted to see who's running what, and what luck you guys have had with them. thanks

i have a fully manual c-4 in my 85. I race circle track but pedal to the metal for 25 laps i havent had a problem with it yet. Pretty easy to installl.
