Well the cam could be in the future. The stock L31 cam is pretty wimpy. The link below is a good read:

L31 cam specs:
* Intake Lift- .414"
* Exhaust Lift-.428"
* Intake Duration @.050"- 191
* Exhaust Duration @ .050-196
* Lobe Centerline-111

According to a few sources, the vortec heads (062 cast) can flow up to .460 lift stock. I haven't been able to verify if the heads on this short block are the 062 cast.

L31 short block heads - 64cc,1.94" intake,1.50" exhaust
