I have always had a little misalignment in the belts since I bought my car 9 years ago. Didn't think too much about it then. But during the rebuild I am noticing a few things. I ordered a replacement PS pump for my 66 Polara 383 out of a reputable place in Columbus OH.
My incorrect assumption was that I was working with an original block. Turns out the block is 68. It has a 4 groove pulley system on the crank.
I replaced the alternator shortly before the rebuild started and had charging issues at idle.
Now that I am putting these all back together, still noticing that the belts are not aligned. The spare 66 block that I have has a 2 groove pulley that is smaller, but the bolt holes do not line up on the 68 block.
will the years change the alignment? If the 68 crank pulley is larger it may be contributing to the charging issues at idle as it would be turning slower.
Do I need to look for a 68 pump/pulley and a 68 alt? Should I be looking for a different crank pulley that can be drilled to line up on this crank?
I was also told that a new harmonic balancer might get the holes realigned, especially since I did not replace during the rebuild. If I should do that first, is the nodular iron or steel type better?
