Nah, he started it un-tuned most likely which is ok for initial startup but don't expect it to run like stock and not smell pig rich until the dyno guy gets ahold of it and dials it in. Every pushrod build I've done has been like that. Fire it up to make sure it starts and runs and doesn't have any leaks or obvious mechanical issues, shut it back down, trailer it to the tuner, trailer it home and then proceed to break it in for 1k miles and roll.
2000 Mustang GT Steeda #0048 34k miles. 99 Cobra 4V swapped, FTBR IRS swapped, exhaust, tuned by James Gordon.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
