i would get a 1407 750 cfm.1406 is made for fuel economy more so than performance even the guys at edelbrock techline will tell you that.(thats what they told me) give em a call they can tell you what needs to be done for best performance.

 

Im pretty sure youll need a larger cfm carb to supply enough air flow but you may want to play arond with jetting and metering rods depending on yor budget to kinda tune it in .

 

i thought the 750 electric choke is economy the 600cfm manual choke (what i have is for peformance thats what it says in the edelbrock magazine.but i may be wrong
