What are factory primary jets and secondary metering plate numbers for 3810 Holley on '67 350 horse L79? Were they delivered for different altitudes? I'm at low altitude-300 Ft. above sea level?
Thanks

#65 primary jets, .076" secondary (don't recall the Holley metering plate # offhand). There was no "altitude" version - they were all the same, and the same 3810 was used on both (base) 300hp and (L-79) 350hp applications.
My '66 L79 has that carb, and it was moved from near sea level to my place near 7000 feet. I had no issues with the carb or the engine, runs perfectly and has for the last 2 years. My newly moved L71, on the other hand......

The secondary metering plate is a #22. Power valve should be a 6.5
