That'll get you fairly close. I see so many guys just pick something from the drop down menu that I always ask. I haven't looked on E-brock's website so I don't know what #'s they advertise. I've read several posts of head flow numbers by guys on the board here that are reputable that I use their numbers if I don't actually have them flowed. I do that for a baseline then when I put together an engine I take the heads and have them flowed to get accurate flow numbers. Hopefully in a couple months I'll have my new engine in and see how Desktop Dyno and Camquest compare to what it really does.
