Thanks men.

The bore is 4.125 now but will be punched to 4.155. No one makes a shelf piston that I need.

Changing blocks or heads isn't cost effective.

We decided to go with soup bowls from Ross. The engine needs rebuilding and must have new pistons so it was in the budget. We have also decided that the only other way to insure a good, long life of the engine without a good quench area will be to go with a water injection system from www.snowperformance.net I am ordering me one also for my 420 and bumping my boost. I been on the phone with Ross and snow performance and we are confident we have a game plan to make plenty HP on pump gas out of both engines. The 434 will run the 4-6 lbs and no more to be safe because of quench. I will bump mine to 10lbs with my quench and water injection but no higher because my block isn't o-ringed.
