thanks 94guy i did not see they had a forum over there ! difference is here i have 5.7 piston bore with a -2cc piston. im pretty new to forced induction coming from all motor or nitrous its a new world for me for sure!
Although this cam works great on roots and twin screw style blowers, it is no where near a turbo cam IMO. I/E duration split is way too wide, LSA is too wide, lobes are too aggressive.
You need something like 226/231 .605"/.598" 114+2 for that turbo and a LS1 engine. Or 230/231 .609"/.598" 115+4.
