Ok so i have a 1978 camaro that ive swapped a 6.0/4l80e into. first few minutes of driving seem fine but as the car warms up i develop a vibration at partial throttle and light acceleration above 45-50. right now my drive line angles seem ok my rear is two degrees down compared to the trans which ive read is what u want on leaf springs, ive replaced the trans bushing. new driveshaft. im pretty confused as of now lol i did order more pinion angle shims to get the angles dead on with each other just in case. anyone know any good ways to continue narrowing it down before i have a meltdown lol. Thanks in advance
