uh... no. its L31.

LS1 is a Gen III small block, which shares almost nothing with the Gen I small block of '55-'02.

the LT5 is really its own animal, not a Gen I, not a Gen II. a DOHC small block available from 1990 to 1995 only in ZR1 Corvettes.

LT1 was a Gen II small block, with reverse cooling (like the L99 -4.3 V8 available in B body cars from 94-96, and the LT4 5.7 available in 96 Vettes and 96-97 F bodies.)
