I'm looking into a stroker kit for the II, it will probably never see a track I just some want more power. My question is this what type of pistons should I get with the kit forged or hypereutectic (why)? Also how high can I bump the CR and still run pump gas either 87 or 91 octane? Like I said this will be a street motor that likely sees no more than a 2000 miles a year.
