I recently purchased a set of glass run channel weatherstrips from
Soffseal for my 1977 Chevy full size van. Although they closely
resembled the OEM part they were not the same and would not fit
properly. They were too narrow for the channel and it was impossible
to raise or lower the glass. Also because of the poor fit they would
frequently simply fall out of the channel.
I have contacted the company to return the parts for a full refund and
will post my experience with them.
One more note: When I placed the order on their website I selected
regular ground shipping. When I clicked the ‘process order’ button it
changed the shipping method to 2nd day delivery for an extra-added
charge of $21.28. There was no way to go back and change this.

Question,
Having never messed with the later GM engines, I don't know so I
thought I'd ask here.

The engine is a LS1 out of a 2000 Camaro. Can the block be bored? If
so, how much overbore can it take, safely?

Thank you.
