rebuilt 77-78 kz1000 motor $6,000.

I had my engine rebuilt by Zack at Zack's Cycle in Milan, MI about 10 years ago.  Cost me $3600, weisco 1075 kit, and cut trans.  He told me when it was all done that was the last one they would ever do.

Trout, that is indeed a favorable price. But that was, as mentioned, a decade ago. Used to get those Wiseco K1015, 45 and 75's for around 400bucks back at that time. Now they want 700-850USD for basically the same thing. And a "restore" is a whole different bird then a re-build. Inflation, it sucks, ha. 

My recent build is a 1197cc Z1 engine, with ported and big valved head, .425" RC cams, welded crank, and VM33 smooth bores. With the carbs and the oil cooler/lines it cost me about $4200 Canadian (~$2930 USD)

The price is a little low because the pistons were used. The most expensive purchased parts were the LA sleeves at $560. The head cost $750 to port and big valve (includes used 37/31 SS valves) and the cylinder boring was $500 (+6 mm over)

I could have built a 1015 engine for a lot less but I already had the 76mm MTC's.
