I hate to dig up an old thread. But... I wonder what the cam specs are on the Lincoln continental 4v intech? I scored a set of 99 continental c heads and am hoping the exhaust cams are at least identical to the rest of the 4v family lol.

The stock cam specs shown in the first post are incorrect.

lincon intake cams are 184 deg
mach, aviator, maruader, navigator and 03/04 cobra intake cams have 190 deg dur
99 cobra intake cms have 202 deg
01 intake cams have 200 deg dur
96-98 intake cams have 204 deg

all exhaust cams have 196 deg duration
