I like the valve cover idea, but even a core is over $200 every where I look, and I am seeing 71/72 Dodge Demon cars pop up everywhere lately (always looking). Any accessories? Any time anyone sells a pulley (40+), engine mounts ($20-$40), A/C mount setup (as much as $350), used stock rockers and shafts (minimum $50) -a complete engine should go for $350(InMyHumbleOpinion). But I believe engines are cheaper and more prevalent up north, and vehicles are more prevalent in the south (rust and snow influences).
