Stroking a gx390

#3
Yeah I know,I have a 420 and 390 but it's worth what I get out of them over a small block.
My goal is over 600cc but it's not going to be easy. Powroll has been doing the route I think I want to take and I think it will solve a few issues most have.

Before someone says I can buy something bigger,it's not the same...:001_tt2: besides jr. Dragsters have 563cc already that started as a 5hp flathead. Cubic inch is king :thumbsup:
