I have a chance of buying a 468 balanced rotating assembly for cheap. It suppose to have 50 passes but still all in good working order. I have not looked at everything yet. The pistons are Keith black HP .200 dome for closed chamber heads. I have iron world grumpy Jenkins rec port 119cc heads. On the Keith Black website it shows this piston would give me approx 9.6 CR with closed chamber heads. What kind of CR am I looking at using my heads? Truck will only be street driven..
