Just wondering if there is any differences in all the different part numbers there are for 96-98 cobra intake cams. I have found 3 different sets of part numbers and wonder if it relates to the different durations and centerlines that have been found with these cams. I know some of them have been measured to have [email protected] on both lobes were others have been found to have [email protected] on the primary and [email protected] on the secondary. I would like to find a set with [email protected] on both lobes.
