That engine was at 13:1 with the iron GT-40P's and ran great on 93 octane pump gas, even on the street. I even raced on pump gas without detonation/knock. In EFI form, I had a chip that merely turned off the emissions functions, brought in total timing by 2700 rpm and boosted the rev limiter. Full timing was at about 33-degrees. In carbureted form, I ran a locked out distributor with 34 to 36-degrees.

Point being that the alphabet cams are old-school and leave tremendous potential untapped. Why in the world wouldn't someone want to get as much performance as possible out of a component when laying down the hard earned cash. Technology moves on, in large part because of what is learned from cutting edge racing....camshafts are no different. The experience gained in the industry over the course of 10+ years has shown that you can have a performance hydraulic roller camshaft for the SBF that retains good idle, driveability, emissions performance (even if not advertised) yet provides kick-in-the-a$$ performance.

Go with a good cam designer/grinder such as Anderson Ford Motorsports, Flow Tech Induction, Bennet, Cam Motion, Isky or any host of other companies. Hell, even Comp Cams has some tremendous products not even listed in their catalog, just call their tech department and ask for more.
