WANTED; 350 w/4 bolt main block! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Like the title says. I need a 4 bolt main 350 block that is either freshly bored .030 or does not need any boring. Thanks.

Since this is slipping down......
I needed a one-piece 4-bolt last year and could not find one anywhere.......all I could find was 2-bolts.
I wound up going to the Chevy place (parts dept) and ordering one.
It was around $600 new.
Another "funny" to do with that block.........Jeg's sent me the wrong-sized pistons (needed 4" bore and they sent +.030s),
I called to get a return number and the tech. said "just bore that block out and use the ones you have" ARRRRRRRRRRGGGGG!!!
They finally took them back after 15 minutes on the phone.

Why the obsession with 4 bolt mains?

Find a good 2 bolt and use the Milodon conversion main caps. They are stronger than a 4 bolt.
