I have a recently rebuilt 289 with the following specs: 4.030 bore Forged flat-top pistons (Keith Black) Stock steel crank and rods ARP bolts throughout Dart Pro1 aluminum heads (170 intake port, 62 cc chamber, 1.94/1.60 valves) Comp roller rockers Comp 260H cam (hydraulic lifters) Edelbrock Performer Air gap manifold Edelbrock 600 CFM Carb (electric choke and vacuum secondaries) Stock water pump and fuel pump Ford Racing head covers PertronixII billet aluminum distributor and coil It has about 2500 miles since the rebuild Its a plug and play motor that has a mild idle and strong, but not wheel-spinning, acceleration. I think it is worth about $3500. Am I in the ball park?
