HAVE A 76 K5 TOOK A 355 OUT, PUT A 454 IN. NOW I KEEP SPLITTING THE CASE ON THE TH350.
TRUCK IS LIFTED 7 INCHES WITH 35'S. IS THE CASE ON A TH400 STRONGER AND DO I NEED A DIFFERENT TRANSFER CASE.
ANY INPUT WOULD BE HELPFULL, ON 4TH TH350,GETTING EXPENSIVE

I have a 84 blazer with a pontiac 400 engine and the 400 tranny with a 208np transfercase and with 38's. Engine came out of street drag car. I'm not sure your torque but I stomp mine with no problems. What gears are you running? If it breaks always up grade to the next size never put same back in. I like the 400 tranny's.
