I have no reference for what is normal with a Fox-era Mustang, so if these sounds are normal, great. I'd appreciate your insight, especially if these sounds are familiar to you.
I have a donor '93 Mustang motor and trans, running the donor's EFI. I have new Edelbrock performer heads and a new Cobra intake manifold. Side pipes are installed. Everything else is as stock as it gets in a Factory Five.
At 6-7 seconds, I think I'm hearing starter overrun. Grounds are good, bolts are tight, starter is new as is the flywheel (~500 miles ago). The sound is consistent every time I start it. Normal?
At about 19 seconds, I downshift from 5th to 4th to make the next sound easier to hear. It sounds like an old movie projector. You can hear it slow down when I'm in 5th. I thought it might be exhaust leaking, but when I changed the gaskets yesterday there was no change in the sound. Any ideas? Normal?

Shot this with a Flip videocam mounted upside down to the rollbar right next to the mirror. I think I'll be replacing the Flip. The sound drops out for an instant here and there. I don't know if the volume is overloading the mic, or if the GoPro is just calling my name.
Thanks for any help!
