Thats really suprising , I live in Canada and have never heard of a production 4 bolt main 305 block .
I am going to investigate this a little further, just for my own interest. I remember a few folks claiming their mid '80s Monte Carlo SS were 4 bolt but when they tore them down they were always 2 bolt main.

I guess you have to wonder why a HD truck would be 305 equipped in the first place ?
