Whats it worth ? 340

Whats the going price for a good rebuildable 340.

Its a 72 block. LD340 intake, headers, windage tray. It has mid 80s 360 heads on it.

I would be keeping the valve covers but I think I have another set I could put on it. Also keeping the carb.

I have a set of 273 adjustable rocker arms I can throw in with the deal. Also have a set of Magnum heads, valve covers, rockers and head bolts.

Is $800 to much to ask I was thinking $1000 with the Magnum heads
