I've been running a BAE Stage 8 Hemi 4.375 stroke X 4.375 bore with a 18-71 DMPE M5 making around 49 lbs. Been running fairly well for years 4.11 1/8 on 10.5's at 2800 lbs. I run mild rpms with a 2 speed trans shifting at 9000 and cross the 1/8 at 9100 I've decide to increase my bore size to 4.446 and keep my 4.375 stroke crank with the same compression 11 to 1. Everything else kept the same also. Question is should it make more power ?? I heard it will "un shroud the valve" my concern with the extra CI will it lose boost going from a 526 to a 548?
