Is there any advantage to changing to an earlier pre-smog distributor when 
de-smogging a 1969 engine? (It's not my engine, and it has already been 
done, so I am just trying to advise a customer who is putting some 1965 carbs on 
it).
Thanks,

Grant - The 1965 110 distributor is the best one for almost all 
"non-competition" applications. (depending on the motor, is it a 110?)  Look for an 
"1110319". The smog distributors relied on some strange (not supposed to use 
the word "retarded") initial ignition settings (4-6 degrees) and a very fast 
initial mechanical advance, and a lot of total mechanical advance. Unless the 
builder can rely on a repeatable, trouble-free 600 RPM idle, the 1965 110 
distributor, where advance starts a bit higher, is the best bet. Oh - and be 
sure to tell him to use the initial advance settings that match the 
distributor - Check the 1965 110 HP specs. And for all the "numbers must match" 
folks, you could always swap in the later housing with the original number on 
it.
