Dude,600bucks is will [freshin]that motor or be a good start on a rebuild.Easy test 1-does it use oil?2-does it smoke or knock?3-blow by from oil fill cap?no-no-no,then the engine prob. ok.,Lot of satifaction from doing it your self and 1/2 the cost.Lifter noise?I did get an1968 engine that had a 1966 cam installed.See under valve cover while running.Oil flowing up push rods to lube and cool rocker arms I think would indicate good oil pressure to lifters[it is hydralic?]by the by,I bought the chevy roller rocker arms from chevy PN#12361323,All BB owners should try I could feel more power [seat of pants] reved cleaner and less wear on canted valves.Does require tall valve covers.One gut I know did use the "NEW" valve covers but,had to grind down top of poly locks. ----- Original Message ----- From: "Jeff Fischer" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, September 12, 2002 1:59 PM Subject: [Chevelle-List] Rebuild or not
