Brent, I have a Edelbrock torker ( 1970 era ) and a 850 Holley on my 66 BB. I believe the Edelbrock Preformer is very similar to the Torker. That is , height wise. They both fit under the hood fine --  you do have a stinger hood ? More important is the right air cleaner. Be sure the air cleaner base is recessed to fit around the carb.   Steve
