lift question

[76 chevy shaker]

i really want to lift my truck and don't know how to go about it. anyone know a cheap easy way to lift my truck? i have 35 16.50 15s boggers on it and want bigger it already has 3.5 inch lift blocks. but it causes my rear end to torque under a load and if i stomp it. i need cheap and easy but has to be compatible with a 3/4 tons axel swap. im completely new to this, so help me out fellas.

rear shouldnt move, check your u-bolts and center pins. cheap lift is a body lift, cheaper is cut your fenders

def check you bolts and pins man, also check your springs make sure they aren't bent or anything, there's lift springs on her efor sale all the time cheep

thanks ill be sure to check the springs and ill get some new u bolts. i had my buddy watch the springs when i take off a lil hard he said the springs and all are torqeing. he said my leaf springs are torqueing into an "s" shape.

maybe traction bars???
