350 Small Block Question

Are (1970-1972) 350 pickup blocks 4 bolt mains or are some 2 bolt mains?
Thanks

The legond goes that all truck engines were 4 bolt...but that has been proven wrong again and again.
With that being said, the only two original 350 engines I have seen that got torn down (in 69 - 72 trucks) were both 4 bolt.

My 69 C-20 had a 4-bolt 350 in it.

My 70 was a 4 bolt. The truck is long gone but the engine is in my garage waiting for the right project. If I live long enough Ha Ha.
