How much would you pay for this 340?

They are J heads... And J heads showed up on 340's starting in 1970... 69 340 = X heads 70 340 = J heads... 70 & 71 340 J heads had 2.02 intakes and 1.60 exhaust same as J heads... Hell T/A's & AAR's had J heads... With relocated pushrod holes...
Truck pan doesn't mean squat, back in the 70's & 80's lots of 340's got transplanted... Anybody remember there was a "Van Craze"... Back then Vans were cool... Not like today...
