383 Piston slap

Hey All
I didn't build it so not sure of the clearances at assembly. It does quiet right down when up to temp so i am guessing that it will one day be a problem but for now i will drive it while i look for a block for a stroker.
My (well,...ALL) 2.2 Turbo II's came with forged Mahle pistons, thay all rattle on a cold start ~45°F & down...no biggie..
