possible engine for my Dart

What that looks like is a grungy 71-up short and 68-70 heads.. Not seing any head bolts. Was it apart? You should not have X heads on a factory blue engine. They would be Js or maybe Os. Either way $1600 is stoned. The 340 for my Demon is a complete '73, pan to exh manifolds, with an Edelbrock intake. Was pulled from car running and I got it for $400. If that one was complete, running, air cleaner to pan w/the exh manifolds and a '68-71 I'd say it's worth $1600 to the right person. But not as it sits. I wouldn't even spend $600 on it. It's a core shortblock, core heads, and a $150 used manifold.
