Edelbrock 1413 on a 340?

The 340 in my 65 cuda is built a little stouter than yours but not much. Have had a street demon, 770cfm holley avenger, 1413 eddy & 1813 eddy on her. All good carbs but have gotten best 1/8 mile results & drivability with the eddy's. I'm biased though because they are easier to tune. Good luck & if you choose the 800 eddy you won't be disappointed.
