It should have the oomph to get me there, or close enough. The cutouts don't change the AFR's that significantly. I've checked plenty of times.

I'm always monitoring how it's running.

In any case, there is pretty much no time out on the street I can aggressively put the pedal to the floor without the tires starting to break loose on the pavement, so plenty of fun for street driving. And as I said, it gets 17+ mpg.

Back to the Firebird. I properly re-timed the cam, it looks like with the thicker than stock head gasket on it the cam was timing was 1 advanced. So I dialed back what I set it too on Monday and set it to what should be 4 advanced. More realistic setting.

The valve springs and engine gasket kit arrived today, so I have everything I need to rebuild the engine now.
