That is a great cam specification for the street. I used it for years in my 350. I advanced it 4 degrees and it pulled like a champ. I didn't have any power accessories, so the manifold vacum issue was not a problem. It idled real nice (for me) with a 2000 stall converter. Going up to an aluminum headed 383 will make your little street machine with short tires a blast to drive. Good luck with the traction
