[QUOTE="na svt, post: 7611459, member: 35346"] Here are some Lincoln and 96-98 Cobra cams specs. We checked some intake cams today from 96-98 Cobras and Lincoln Mark 8s. Part numbers and durations are below. The Cobra cams are part numbers: F6ZE-6A270-AB F6ZE-6A271-AB When checked the durations of the four intake lobes were 204-205 degrees. The LCs were the same for both the primary and secondary lobes. I beleive the Ford specs state 206 degrees and it is very possible that there was 1-2 degrees of error in our measurements. Either way, these cams have at least 20 degrees more duration than the Mach cams. If Installed with about 8-10 degrees advance there will be no torque loss but there will be BIG hp gains. and the Lincoln cams are part numbers: F2LE-6A270-AE F2LE-6A271-AE These have the same duration as the Mach cams; 184 degrees but do have a different part number than the Mach cams. I have another set of Mark intake cams to check (different part number) and also a set of 99/01 Cobra cams. Should have an update soon. [/QUOTE]
