If you changed pistons and/or ran thicker HG, and could get it closer to 10:1, that'd be a great street ratio. Would need premium gas 24/7.

 

Don't pick cams at random or off a shelf. Everything from curb weight, usable powerband, gearing, cr, etc. need to be factored for optimum benefits + driver expectations (i.e. talk with the rep and go custom grind). If it was a V8, I'd say favor a torque cam and sacrifice redline for excellent acceleration; for a 4 banger, you'll want more rpm, which needs decent valvesprings, etc. and might be an obese dog for DD unless you like winding it out constantly.
