compression ratio on pump gas

We need to know what dish piston he's talking about though..

If its a d dish...then it has the flat top on the quench/closed chambered side of the head and will work just fine.

Along with proper quench....Its carefully modifying the timing curve, gears/car weight 'basically tuning' that will allow for 10.5 comp with int early closing and pump gas.

But that cam closes at 60*!!!!
It shouldnt be too hard to make it work on pump gas at all.imo
