Excuse me for revisiting this 'older' thread.
While there were many recommendations and info on which carb to use, the OP seemed to be interested in (as am I) as to why he would need an 800 cfm, or more, carb when the calculators he used shows he needs about 624 cfm.

Using what is now considered to be an outdated formula, 624 cfm.

Read the link Steve C posted above for a more modern and accurate take on carb sizing:http://www.pro-system.com/pjames011900.html
