you're lookin at $500ish for a rebuild kit (that's gaskets, rings, main/rod bearings), 100-150 for an oil pump (always change when rebuilding), and then maybe another 2-300 in assorted seals/parts depending on the shape of your engine. Always tear down first before ordering parts, as you can get kits with pistons if they're worn out. Generally not necessary, but good to know before ordering. cam bearings are $30 if you need them. head bolts are about $30. Should be able to do it with around 900-1000 in parts.
