Default Induction Flow?(Desktop Dyno)

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 already have an LT1 file made up for DD2K3 if you want it. It's almost right on the nuts for power curves. Sadly though, the cam specs are a bit off in order to do that, and the peaks are like 500RPM higher.

I think 215cfm is the max stock heads flow. (I adjusted those as well).

You'll figure it out right-quick!

If my files don't work for your version, just PM me and I'll "fix" it for you

Flow file should be accurate stock flow numbers.

So that's the file for a Stock LT1?

I'm trying to put in the specs for a CC503, do I changed the seat to seat timing or the secondary? I'm confused there.

It's for a stock LT1, but the cam SPECIFICS are massaged greatly to put out advertised power. With the correct info, it's quite a ways off. And roller setups are seat-to-seat, but that throws things even farther off :\

Find the cam card for the cc503, look at all the wording really closely, then look at all the cam stuff you see. It'll all come to you then (I'm trying to help by being vague, but if it still stumps you, I'll show you what I mean. Crane's site should have the cam info I'm talking about, they come on cards with the cam.)

I was able to match it all up, I just wasn't sure which parts to change.
