Ive been rebuilding a 97 cobra engine and everything is going good except I cant find a straight forward answer to the cam degree issue. I'm running Ported B heads with Stock B cams, I have the intake and exhaust both set at 113.5 center line and that gives me a 133.5 LSA . Ive read on different places throughout the internet that Ford Stock settings for the B heads were 122 intake and 109 exhaust center line giving a 115.5 LSA and they recommend a 114 LSA however none of this can be verified. Motor is going to be N/A for the first few miles then it'll get a 150 shot followed by a Kenne Bell Super Charger . And Yes the bottom end is all forged and has ARP hardware so it wont break and can make a ton of power. Im sticking with this setup because its going to be mostly a Show/Street Car. Anyway the issue im having is has anyone set there cams at or around this spec and how did it run? Ive heard the only reason ford retarded the cams was for emissions. Ford has No info at all of what to set the Center line at on the subject and Ive read dang near every p[age of the Factory 97 service manual. Any help is appreciated.
