B&M shift kit question

Tylers71 · Jan 22, 2003

I gotta 71 chevelle and a 400 bored 30 over sbc. I have a th-350 tranny and I bought a B&M shift kit. The motor is pushin about 400hp and the car is an everyday driver. I don't know about the compression or cam or anything like that. The rear-end is like a 3:07 or close to it. real high. I think this will keep my rpm's down. My question is should I put the RV/Heavy Duty or The Street/Strip in? I want it to run like low 14's or mid 13's if possible. What do you guys think I should do? All info appreciated!

Send it back and get a TransGo kit,
Then install Transgo on Level II.

Is it a transpak or just a shift improver kit? I install transpaks on level II, street/strip. I have installed a bunch of em and havent had a failure. Make sure you have an inch/lb torque wrench for the valve body bolts and follow the instructions to the letter.

Trans go is the way to go, it shifts better over stock underlight throtle but shifts alot harder under hard throtle and its really nice. o and stage II of cource
