Edelbrock Heads for 318
No ATI builds their own motors, they say just 1 person does the work putting it together, Mopar's are crap, I would trust ATI racing for my motor. This is what it says--hypereutectic pistons, forged steel rods, cast steel stoker crank, hydraulic cam. The race but for street use they claim has a forged steel crankshaft and pistons , eddy heads and a soild cam. Guess thats why its 11-1 it has those eddy heads that cut the comp. down 1 point. Other options are available.
