It will work with a manual choke cable installed, I have used them on slant sixes before with the choke thermostat removed. Other than the minor inconvenience of the manual choke, I couldn't tell any difference in overall performance or driveability on a '71 \6. Just make sure to hook your distributor vacuum advance to ported vacuum and cap the unneeded connections. Memory is failing me on the air cleaner stud bail assembly. It looks like it uses the same one as the Holley, but it's been a while back. I went with an adapter for 5-1/8 inch neck air cleaner and had to make my own bail assembly with a 1/4-20 bolt and nut and an artfully formed paint bucket bail.
