For reference, each damper was individually balanced to each crank. The drilled holes were part of the balancing process. Vibration Damper Listing '67-'69 290: #3180477
290 Vibration Dampers. The one on the left is 1966 only. The one on the right is 1967-69 290 Damper on the left, '67-'69 343 on the right (Note no cut out in the weight pad)
'68-'69 390 Vibration damper on the left, 1970 390 Vibration Damper on the right. The off-set weight goes 180 degrees on the 1968-1969 390. The off-set weight goes 240 degrees on a 1970 390 ( all are 3-bolt) 1973 and latter 4 bolt Dampers. 304, 360, 401. The off-set weight goes 90 degrees around on a 304 (both 3&4 bolt) The off-set weight goes 240 degrees around on a 360 (both 3 & 4 bolt) The off-set weight goes 180 degrees on a 1971-1972 401. (3-bolt) The Off-set weight goes 240 degrees on a 1973 and latter 401 (4-bolt) Edited by SC397 - Apr/23/2012 at 6:29pm |

So 70 390 balancer won't work for 70 360? I thought they were same.

I need to make a 4 bolt balancer that will work with my 290 for the accessories from my '82 Honcho.

This makes no sense to me. If I went to the dealer in 1978 and asked for part# 3196925 how would they know if I wanted the 360 version or the 390 version? So real question is are we talking about a casting number or part # |

There is no such thing. All you can do is take any 4 bolt balancer and match balance it to an original 290 balancer. |

what did you say? You said you want a 4 bolt balancer to go with a 290. It does not exist so you can take ANY 4 bolt blancer and have it match balanced but there no such thing as one to bolt on without first modifying it to match the 290.
The closest will probably be the 304. |
