I have a question. I already bought trick turbo stage 3 Now I need cam and valve spring upgrade. I have see lot popular run isky cam? Is there any good cam ok for turbo and in cause if I end up back to n/a which cam still accpet too. I would like see your opinion real quick before I can find right direct for cam. Is that worth run dual springs ?

 

This going on a 5.3? I would go a little bigger than typical. Most guys like the isky triple 12 but I would go for the isky 218 or a TU1 from speed inc. Both are large enough to be lots of NA fun and will respond to boost in a big way. Doubles are great, but I would just have the cam maker isky or speed inc recommend springs.

 

What exactly size does isky cam is? What lift valve springs for that too. How
Much cost for isky?
