L79 4160 Holley Carb Questions

[Dave B.]

I will be bringing a '66 with a 4160 LIST 3367 Carb to the Colorado mountains where it will be driven from 6000 to 9000 feet. I want to have the carb redone, and am looking for advice on what to have done. I know that the jets need reducing, and have seen that the primary is around .064 and the secondary .073. Also have read about the 2%/1500' reduction above sea level and that older Holleys were set rich.
Any advice on settings of jets, power valves, parts that should be replaced, etc, will be greatly appreciated.
Thanks...Dave

the LIST 3367 should have a # 65 jet in the pri, a # 22 plate with a .076 drilled holes in the secondary and a #65 power valve from the factory.

Re: Thanks, Clem.....

I'll apply the 2% rule to these numbers for my final answer.
