383 LT1 cam suggestion/recommendations

Hey fellas I wanted to pick you all's brains a little :thumbup:
I recently built a 383 LT1 TPI for a customer of mine and he wants
to be more street than strip. He is looking for speed in a second gen trans am/1979. I'd really appreciate any suggestions. I was looking into not so much duration but more lift, but I'm not a cam expert.

Thanks,
JD
