Did you get a warranty with that reman?
Piston slap will go away after the engine runs for a minute. Sounds like that lifter/cam incident got to a bearing.

Just Spoke To The Vette Expert At Our Chevy Store Yesterday.he Heard The
Sound & Said That One Of The Rods Has Excessive Clearance,more Than Likely A Bi-product Of The Reman Process.the Sound Has Gotten Worse Since The Post Yesterday So The Vehicle Is Not Being Driven At This Point.fortunatley The Reman Warr Covers A New Short Block.
Hopefully This One Will Have The Correct Tolerances.this Noise Developed In Less Than 2,400 Miles.
