The 289 HIPO was not offered in 1968. There was a running change from the 289 (standard) to the new 302.

Scroll down the page and read the dampener and counterweight entries. It sounds like you may have mixed components causing the vibration.

tear it down and have the rotating assembly ballanced ,and check to see if the converter has tossed a balance wieght

i had that issue when i did my 302. do you have the proper torque converter. the ballance of the torque converter may be off and that will cause a wicked vibration.

did you find/fix the problem. fill us in so that if anyone has the same problem they will know where to start looking. new antidotes are always a good thing. every car is different and usually has a unique problem. you could help someone else or let us know if one of our fixes helped you.

check the casting codes on your rods and pistons a different code could result in some serious wieght issues

Just a thought, I don't know if you have a vibration while the car is in motion or not, but if it is, I knew a guy that had a street rod that had a nasty vibration.... he replaced everything and found out he had the pinon set at the wrong angle. I hope this helps. Good Luck!

good point, forgot about that. mine was only at Idle and that was the converter.
