hi all

i have to choise about 4 cams and iwant to know which is the best for my trans am 99 m6:

the cams :
1: x1 cam Duration 230 ,227 lift 591 ,571 lsa 112
2: z1 cam Duration 236 ,236 lift 585 ,585 lsa 112
3: s1 cam Duration 244 ,244 lift 612 ,612 lsa 112
4: R1 cam Duration 232 ,236 lift 575 ,578 lsa 114
and my mods is :
lunati stroker 383 ci ,pro charger 7 psi ,lsx intake and throtle body 90 mm,
stg 3 heads, 12 bolt 3.7 , water pump , zo6 air mass , jesel rockers adjustable, liffters,

 

You are running boost, so call MTI and get a boost cam rather than a "named" NA cam. Of the choices listed the 232/236 114 probably best matches your needs.

 

of those 4 i would go with the r1 since it has a traditional split and a wide lsa. however, you could get a cam specced out that is much better suited for your application than any of the cams you listed.

 

i want more info
