IF SO, you will need a cam with WIDE lobe centers of 112 to 118, depending on your intake and exhaust duration numbers.
Are you running a Single exhaust outlet ? or duals?
IF single exh. then the overlap and exhaust duration may have to be decreased from what would be used if you had duals.

IF YOU HAVE A VACUUM RULE,,, Maybe USE THE just relealsed for 2009, the ISKY 201SL1/14, it is the same as the 201SL1, but has a 114 degree lobe seperation to get more vacuum at idle, instead of 201SL1 that has a 108 degree lobe seperation.

the 201SL1 cam specs below are ths same as ISKY 201SL1/14 except it has a 108 Lobe seperation.
