A 7.4 vortec? On my phone so I can't look at the file yet.

What mods? Stock? Cammed? What?
Edit: Looked at it. I think you're going to get a lot of KR due to all of the timing you've put in it. Your PE is also set to come on at 1200rpm at 90% throttle. You'll probably get more use setting your vacuum and TPS positions to lower numbers.
Also, your cylinder volume. I've calculated mine to be 0.93005 L, where'd you get yours from?

It looks like it should run. The main thing I had different was the alt L term and F term in the system options, I have mine at 1, but otherwise i think you're okay. Those might not prevent it from starting either.

OSOLETE489 , Mangonesailor thanks guys
the cyl volume was stock from a blackbox tune ,as far as the pe over the last few years I have used this combo and it work well for out of the box power and oddly better fuel mpg as reported by customers also did anyone see the calibration notes , the timing files are from an 8.1 , actually all of the changes are in the notes
thanks

I'd be wary of the 8.1 timing tables into a stock motor. But it looks like it'll run. Everything just about lines up with my tune, except for subtle things (Like my startup VE is different due to my own tuning, DFCO, etc...)

I agree with mangone here, stock cam probably won't take that much timing, especially on 87 octane if that's what you run, might stand a chance on 91.
