I am looking to buy some used engine parts. They can be worn out stuff you would normally discard. They will not be placed in a working engine. All need to be SBF stuff for 289 or 302 or 5.0   This is to be used to build a v8 internal model to be used in educating some students on the workings of automobile engines.
Let me know if you can help out.
Need:
Set of 16 valves, 8 intake and 8 exhaust
Set of 16 rocker arms. Prefer stamped steel type rather than cast iron, but will consider any.
Set of 16 lifters, all roller or all flat tappet style.
An old camshaft
An old timing chain set, must have iron gears, not plastic
ONE connecting rod C3 number preferred with a piston, or a matching set of 8.
An old harmonic balancer, any condition
An old flexplate for automatic
Crankshaft

Since I am looking for your old worn discard type parts, they need to be really cheap or exchanged for garage points.  Help me put some useless parts to good use.

Let me know if you can help out!!

Thanks
