71 340 engine value

Not likely. Machine work is 25% of the price of this engine, minimum. Many guys spend well over $500 on maching. If its done right with good parts by a mopar(not chevy)Guy, 2 grand is a deal. Cost of a block, cleaning/tanking a block, decking, Boring, align hone,new or freshened crank, pistons, rings, reconditioned rods, bolts, bearings,timing chain, cam, lifters rocker assy, head work or new aluminum heads, intake, carb, gaskets. None of that is cheap like a 283/350 build. Check that sucker out 9 ways from Sunday good and good luck with purchase!
