I Chose the 383 Big Block

Call Ken at Oregon Cams and tell him exactly what you're looking for. He will steer you right.
A strong second to this! Ken has ground me 3 different cams and each one has performed better than expectations in the engine they went in. Also, there isn't anything wrong with a 383. You do you. You're also in the right place to get quality advice if you can sift through the pontificators. Welcome to FABO.
