New clutch installed and bad wheel hop?

It is your pinion angle. Had this exact issue with a maybe 400 horse 383 4 speed in my 1968 Dart. Tried different clutches, springs, etc. Old 4 speed racer said get 4 degree pinion angle shims, place them in between the axle perch and spring. Angles your pinion down. I could barely pull out without my car shaking badly with wheel hop. I did the above. Problem instantly solved. Got the shims from Calvert racing.
