170 stroker turbo build

You will need a custom piston for the stroked 170 engine. Both Doctor Dodge and Dart270 have talked about the combination. It is lighter and close on the CU to a 225 so it is a good consideration. And in the slant series it does have a little class advantage.
I seen that and Charlie mentioned it too. From what I have read they are recommending put the 198 crank in with the 170 rods and pistons, then take your measurements. CC the combustion chamber. Then call a piston company and see what they have or recommend. Also check for clearance for the valves once you have your pistons.
