1970 455 rebuilt

I have a 1970, rebuilt 455 for sale. The numbers have been removed, due to decking the block. The casting number shows 1970, or 71. Under the timing cover, in the recess, above the cam gear is stamped "70". I have $6300 in receipts, from 2005. Align bored, torque plate bored, torque plate honed, reconditioned rods, balanced, new .030 pistons, new cam, etc, etc, etc. Looks like it was a stock rebuild. Dished pistons, erson 550 H cam. The heads are later (75/76), and also completely rebuilt, but wont fit the early block. They are available, as well.
