I've got a B&M shift kit that I am finally ready to install. This is a stage 1(RV/towing) or stage 2(street/strip) shift kit. Which one would any of you guys prefer. I have a 79 Jimmy with a th350, 4.56 gears and 35's. Thanks Well guys, after a long talk with my grandpa and his experiences with B&M shift kits he suggested the stage 2. I took his suggestion and considered it. I talked to muddysub and we made it final, I'm puttin in the stage 2. This morning mudysub(Scott) and I started. What a mess!!! ATF everywhere(I need a drainplug). Anyway we went through the process of removing all those internals and modifications to the separater plate and check balls. When we were complete I test drove it. All I can say is it is awesome. It doesn't slam into gear as harsh as I was expecting. It isn't uncomfortable at all. Under normal driving conditions it is a very positive shift. I like it alot. But don't get me wrong though, it does have a hard kick if you have it to the floor going into second, enough to chirp the tires. All that I can say is that I am very impressed with the stage 2. It's great.
