Slant 6 stroker kit?

Why the 198 crank in a 170? With an overbore you have a 210. Only 15 cu in below a 225 and at least 1000 RPM more.

Yeah but he left out the .100 over bore. That's what I was gettin at. They take .100 fairly easily so I wonder if you couldn't bore the 170 enough to make it a 225 with the 198 crank?
