I recently had my 77 Gremlin smog tested after refurbishing the car and putting it back on the road. The original engine was toast so I installed another 258 six from a lil 'ole lady Hornet (68,000 miles) and used the 2-bbl manifold with a fresh factory rebuilt Carter BBD (non electric) carburetor. What the numbers mean: Max is the maximum allowable emissions; Ave is the average emissions for all vehicles passing the smog test; Meas is the emissions measured from my car. Idle RPM CO2 measured: 9.90% O2 measured: 7.10% HC MAX 220 ppm HC AVE 60 ppm HC Meas 3 ppm CO Max 2.00% _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
