447 HP Vortec Small-Block Build - Budget Sledgehammer
One of the nice things about the late-model GM small-block is the sealing improvements found throughout the engine assembly. The Vortec engine's intake gaskets feature a plastic retainer supporting O-ring seals around the ports and water passages. These are virtually leak-proof. Note the OEM hydraulic roller lifter arrangement installed in the valley. The lifters are actually the original, used, GM units from our core. View Related Article
