Can I take an old 4 bolt main 350 block and put my heads and intake manifold and put it in my 98 k1500 sierra ?
Sure. Only issue is the water pump. The pump turns the opposite way between the v-belts and serpentine. And the older block has a water pump bypass hole on the passenger side below the lower bolt. People tap it to a pipe thread and seal it.
