Darren-
I don't have any advice- only my own experience. I have a "77--455 with
carb. set for California-68 jets. Thats the way it came stock. I tried
both a 70 and 72 jet but found my efficiency went to "hell", as they say
so have gone back to the original 68 jet. Whether this is really the
best I don't know, especially with the crummy gas that is sold in the
south land.
Just my experience no advice!
