"Don't worry, if i drop the clutch it will start!"(help)

Just did a rebuild of my 87 Shelby Daytona, most things seem to be working fine but when I bring the car up over 3k rpm and let go of the pedal it will stall while moving. The car is driveable but... its a little unnerving. The car hasn't been properly timed yet, Im thinking that would be the main thing, Any ideas?

so youre pretty sure something is wrong with the timing, but instead of fixing it youre asking us?
fix it and try again.
