    Pat, yeah I did check tdc and it is at 0. I do currently have one blue and one silver (light) springs installed. You think the red (28 degrees) would be the ticket? This motor really seems to like alot of timing. Thanks for your help.

    Seems like we get a lot of these on here. Sounds like your timing is OK. I think you may be running out of fuel. Like Pat said, monitor the fuel pressure at the carb while running particularly where it stumbles. Tank vented good? Fuel level in bowls set right? Are you running slosh tubes in the secondaries? That is not a big carb for a 454.
