Too many variables to state a number. But I'd guess somewhere between 400 and 450 rwhp.

Watch your compression...59cc chambers with that small (overlap) of a cam, and 91 CA octane might not fare too well.

Watch head to valve clearance with 59cc and that cam. I would use stock MLS .050 head gasket but still check.

430-450RWHP depending on tune.

Will you have any concerns about passing a smog test? If so, it would appear that the cam duration is beyond typical limits (224 or less) even with a tune. Just my opinion...
