Eddy 1407 or Holley 3310-2?

I just about have my car wrapped up for the track next month and I don't know which carb to use. I haven't torn down the motor yet to see what's actually in but the previous owner said it was a 318 stroker worked heads and he said it was around a .500 lift cam. I don't know how true this is but it took the eddy 750 cfm carb with no problem or delay. The car was built for racing. I know a 750 is big but with the vacuum secondarys on the holley would there really be an issue? I don't really care for the Eddy and had my holley sitting around and what to try it I just need some opinions on either carb. Thanks for the input.
