now that i found out i have a th350 tranny in my 68 ss396, i am going to rebuild it this weekend and i want to install a shift kit in it. which brand is best and how much does it cost??

also anyone ever install a corvette clutch pack and how does that help performance??

I have a Turbo Action kit in my race car. It was about $20 15 years ago. I have two other kits in another car and a truck but I like the TA the best.
