D o more research. Don't stroke it bore it. Do a 2.3 - 2.5 SR like me. 92 mm with sleeves is as big a bore as you can go on SR. Its cheaper than that BC stroker kit garbage. Your SR will still be ok to Rev to 9k like mine and you will hit your power goal on pump gas. You can buy the sleeved block for $850 from www.mazworx.com.
