Diff between S/C L32 and an S/C L67

[Keet04GTP]

What did they do different in '04? Did they use the L32 block and put the Gen 5 M-90 on it? I'm confused... I can't see the difference...

pretty much the lower intake and the genV. there might be some better hardened internals and slightly different compression ratio, but nothing major.

Stronger powdered sinter forged connecting rods. Intake ports "mildly improved". Slightly larger valves. Return-less fuel system. Gen V. Electronic TB.
