I read the CAM guide on the site, and have been researching for quite some time.. but still have one or two questions. I'm about to pull the trigger on a TR cam kit- (now is the time to steer me away if I'm going at it wrong).

Comp Cam single springs
TR stock length push rods
TR 224/224 .563/.563 cam.

Do I want a 112lsa or a 114?

Which is safer on the engine? Which is "better"?

This is a street driven 2001 Z06 and I'm looking for 400+rwhp (401-415 I'm guessing)

I have intake/airbridge/kooks LT's with HF cats so far.

The Z will be "street tuned" after the install.

Any advice???
