what year?? The later ones have a diff block # than the pre 80s. Late L82 blocks are same cast. # as L81 & L83.
As for pistons, they're the TRW forged 464664, 464664 is stamped on crown, they have 1 large valve relief, flat top piston, trw forged on underside os piston crown (heat transfer pad...the ribbed stuff)
rods are pink rods, I think X-rods not certain.
Crank is forged, easily distinguished by wide parting line, cast cranks have a thin line would be any of these I think
3892690
3941182
3941188
heads: 462624 76cc smoggers..I think w/ screw in studs.

TT it's a 1975 L-82.
Fauxs that's similar to what I remember seeing.
I think there was a guy here with a 1973 that had a web page with all the engine spec's on it. I need some documendation stating exactly which pistons and rods were used in this engine. I'm about 99.9% sure they are pink rods as I doubt anyone has changed them until now.
Thanks for your help,
Gary

This guy has a good 73 site that I go to for tech data. He has some L82 info, but specific to 73.:
