The V8 Owners Forum -

Has anyone had any dealings with this company, They do seem pretty well clued up with Buick stuff, and they do what appears to be the old KB Buick stuff as well under their own name,

I can see an order for some bits in the near future,

They are well respected in the buick V6 arena with a natty ally block for those with cubic dollars.
