850 apd on sbc
#8
i think your in the ball park..I had a 511ci and APD built me a custom Alcohol carb and it was an 1150cfm
the only thing i see that would concern me is your compression. Alcohol responds well to compression i think you would see more gains on the gas to alochol switch if you were 14 to 15:1 compression..

850 should work fine, I assume its used and not from apd if your asking. My question would be does it have the same air bleeds/jets it did when done by apd ? Call apd and ask for Joe or Randy and see if they can tell you what its suppose to have. Remember to back timing off some.
