What is the LT1's Induction flow in CFM; does it have anything to do with injector size?

I'm playing around with DesktopDyno and it's the only thing I can't figure out. Help da newb.

 

I believe ~630CFM or so. It's more important that you get the heads/cam right. I don't happen to have the stock cam specs off the top of my head, but you can get all of Comp Cams specs online. I have a good stock LT1 head file, let me see if I can find it for you...

Probably going to need to right click and "save target as"
