Re: 3/4 ton big block with SMOG?
TLM = 72 RPO L47 402 with Air Injection Reactor - applications show C10 and C20.
Yes, I find that surprising, I haven't seen smog on a C20 before either.
TKM is also an L47 with AIR for C10 and C20.
There are non-AIR codes for 72 big block C20/30 (only, i.e. not available on a C10) (TKW, TKX).
