Used that cam many times, it's a great choice for any truck or mild performance application, where smooth idle, and strong low end power are required, with broad mid-range power. 

Larger cams, especially "RV" grinds really need increased compression as they shift power up in the rpm range, and hurt performance at low rpm's.

The CS-274 will also be the hands down winner for fuel economy.  We've hid mid-20's with that cam in several applications, including a 1967 Impala SS I used to own with a 327cid engine in it.  It was backed by a 4L60 transmission and 3.31 gears....Cliff
