1988 L98 - Forged Crank?

Hi,

I've got a 1988 IROC with a 350 L98 engine.

I looked up the engine and it appears to be the same year as the car, so I assume it's probably original.

The engine number indicates it's actually an L05, but apparently it was common to use L05 blocks for L98 Camaro engines.

The table I used for looking up the engine details also suggests that the 1988 L98 had a forged (steel) crank, but this is ambiguous.

Did the 1988 K98 have a forged crank from the factory?

I dont think any snuck in the Fbody line, other than the Firehawks. I think corvettes may have got them?

That's the thing. The Camaro L98 was supposed to be the same as the Corvette engine, except for the aluminium heads.

True
Vette L98's got cast cranks and hyper pistons.
Last forged piston in Vettes were IIRC in 84
