Which Harmonic ?
Gonna try to make this short... the 350 I have has a 6 3/4 by1 5/8 it had a long pump. With short pump and stock pulleys nothin' lines up. Tried a/market chrome pulleys same thing. So I got a 6 3/4 x 1 1/4 and a 8 x 1 1/4. Which one to get it to line up. Has p/s also. If 6 3/4 isn't right then 7'' just readin' the rule! LOL!!! Tried shimmin' and both pumps with all the pulleys. Always a half a groove off one way or the other. With the thicker harmonic do i have to go with the larger diameter to offset the half inch in thickness or does it matter? Whew alot of spellin' for a hillybilly!!! Thanks in advance Weasel.

The face of the balancer does not change with diameter. Are you sure that the balancer is installed all the way on? If so, then you are not getting the correct pulleys.

The balancer wont make a diff on the pullies. From the 283 crank Hub, to whatever you want to bolt on the distance is the same from the face of the balancer to where it bottoms on the timing chain gear. You need all the pullies, accessories, brackets,waterpump off the same eng to make things work. Good luck,crazyL

helpful idea
If this is a replacement balancer (off another engine) make sure you are using the correct timing cover.
For example: If you are using a late 70's balancer that times from the top, the balancer cant get where it needs to go (into a recess) in the timing cover. The timing cover on pre 72 blocks are smooth and the ones from the late 70's up are recessed to allow the balancer to slide a little farther back. I just changed the balancer on a 69 307 to one from a 1980 350 and I had to change the timing cover for it to match up. If I didnt, i could wear a hole in the timing cover. My .02 warrens69gmc |
