78 Engine Suffix & Carb broadcast Codes
I'm surveying 78 engine suffix codes (CHW) and their corresponding Q jet broadcast code (BHS).
These codes are found on the driver's side rear of the carb and will be stamped vertically (up and down). If you've have got a 78 and can contribute, I would appreciate it. here's what I'm looking for (and here's what I have):
Code / GM Part # / Engine / Power team
BHS 17058203 CHW 350/185 M21
? 17058502 CLR 350/175 M38
BJT 17058504 CLR 350/175 M38
? 17058582 CLS 350/175 M38
? 17058584 CLS 350/175 M38
? 17058202 CLM 350/185 M38
BHT 17058204 CUT 350/185 M38
? 17058206
BHZ 17058211 CMR 350/220 M21
? 17058210 CMS 350/220 M38
BJM 17058228 CMS 350/220 M38
My apology if the CF formatting messes this table up. If you have something different...go ahead and list it.
I might add that high altitude and California emission codes are the more challenging to find due to fewer units produced.
