depends largely on the spec... most builds I have seen tend to hit 2k +
rods and pistons alone will set you back a grand... then there is all the gaskets which can run to 200 ish... rebore is 200 ish, block decking is only needed if in a bad condition as a rule..
Normally a good idea to replace stuff like oil pump, crank seals, oil pump chain an tensioner, new big end and main bearings plus new mains bolts.. I could go on...
