Shudder on hard acceleration from a dead stop 727.

Mine did that behind my 383. Had over 150k on it at the time. A full rebuild with new bushings, clutches and bands cured it.
Hmm interesting, you dont know what the exact cause was though. Im probabaly just gonna enjoy the car for now because all ive done is work on the dang thing lol. Vibration isnt horrible plus i cant afford a rebuild right now. Buuuut if anyone does know the cause for vibration on hard accel every now and then let me know! And thanks demonic.
