I wouldn't look for huge power increases over the present engine. Chevrolet submitted a redesign two times previously that were rejected by NASCAR. NASCAR had over 40 design parameters and demensions that had to be followed for the cylinder heads alone, far from a clean sheet of paper. The largest advantages are safety and fuel mileage potential then power. NASCAR's best interest are served when all the mfg's engines are as equal as possible. Once any new design bugs are worked out I look for fuel mileage to be the most improved feature of the R07.
