I know you can't always go by wikipedia... but what's this talk of a HO version of the LC1 in the 83/84 Firebird?

The longitudinal LL1 was a high-output version of the LC1 produced in 1983 and 1984. It was an optional ("L-code") engine on the Pontiac Firebird with 125 hp
Applications:
1983–1984 Pontiac Firebird
Is this true? And if so, how can you identify it vs the vanilla LC1?

The database on the TGO tech data section doesn't show anything. And the only other place I can find info on it is from some Firebird "autobio" book. As far as I can tell if there really was a LL1 it is silly rare. Either way, the later MPFI 2.8 LB8 V6 made more power anyway.

Ahh, ok, I didn't think they offered a different version of the 2.8 back then!
