In none of these forums where this comes up, do I ever here mention the fact that all L82's due to their internal construction of Forged 9.0 compression pistons, pink rods, 4 bolt mains, windage tray, push rod guide plates, 2.02 Intake Valves, 1.60 Exhaust Valves
Sound Completely Different than ANY L48,L81 or L83.
Just listen to the engine idle beside an L48 and it's obvious.

And L-82's didn't have "pink rods". That was LT-1's.

forged pistons could have a little piston slap at start up and floating wrist pins could also make more noise at times. and the 71 - 73 LT-1 short block was identical to the L-82 short block except the camshaft.
it did sound different than the base engine. mostly when cold.

LT1 1972 rods same as 1973 L82... In fact most of the lower block is identical

The LT-1 did indeed have forged pink rods but the difference from the L-82 forged connecting rods is minimal:
350 high performance (LT1)
large journal
forged steel
pressed pin
shot peened
heat treated
magnafluxed (known as "pink rods" due to the pink residue)
Magnafluxing and shot peened are the only difference. For the street, no real world difference.
