3/4 ton big block with SMOG?
Just pulled in a 3/4 ton Suburban with 402 and TH400. It is a TLM suffix code engine with SMOG on it. All 3/4 BB trucks I’ve seen have been non-SMOG. Was this a Burb thing or assembly plant thing? It is a Flint built truck. All dates appear to match up with blue sticker on door so I don’t think the engine has been changed out. Any ideas?
