Thickness of balancer for 327

[skokie]

I was talking to a guy that specializes in selling balancers and he was telling me that truck 327 balancers were thicker than others as well as the same thickness as the 350s that were put into the 69s. Now the reason I ask this is because I did have a issue with pulley alignment before I installed my 8 balancer. So here is my question is this true? Say could a truck 307 and 327 have a different thickness of balancer? Also by thick I mean from front of balancer to the back.

I know another wacked question from skokie LOL

Generally the length of the balancers are the same. The diameters and the widths of them change from engines and years but the mounting surface of the pulleys usually stays constant no matter what balancer you have. I hope that make sense,and didnt confuse you. Early 327 had very thin balancer rings of a small diameter but still had a snout location for the pulley to mount to,which would be the same as a later 327/350 except for the newer ones being thicker and larger diameter.

There were a few common balancers from the late 50's to 67 that were very thin and small diameter due to the small journal crankshafts. Once 68 started using large journal cranks,thicker and larger diameter balancers were used then. I believe that 68 and up used 6-7-8 inch balancers depending on applications.
I guess with my rambling I am trying to say that the surface which the pulleys mount on the balancer should all be the same as long as the balancer is pulled all the way on to the cranks frt snout.

Yup, what he said ^ even the old 283s with a steel hub(no damper ring), were the same depth from the face , to the back where they bottomed on the crank gear. you have missmatched pulleys, or the balancer is not pulled all the way on.....crazyL

Skokie, your miss alignment is (what I believe) to be a common problem. I went nuts trying to figure out my misalignment problem. (I can’t count how may hours I dedicated to getting to the bottom of this…..)
But in short, I have proven that this is a common issue –and probably goes unnoticed most of the time. Summit even sells spacers to correct this. I wonder why?

I made my own to fix my problem. I have a few spares (my proto type) that I can finish and give you. You pay the postage and they are yours. Probably 2.50 to send by mail. Here is a picture of what they look like.
I think I did a write up on how I did all this.
