454 Mag MPI Mods - HP Guesses???
Did a full rebuild on my motor but didn't get to put it on the dyno, looking for guesses on the new HP. There are a lot of discussions on mods with the carburated version but not as many with the MPI.
454 Mag MPI (originally 385 HP, w/flat tappet cam)
10:1 Compression
Bore .030 over
EMI Exhaust
Inconel Valves
H-Beam connecting rods
Mahle pistons
Liberty Rocker Arms
Manley Push rods
Edelbrock lifters
Hydr. Roller Cam
Intake Net Lift .569"
Exhaust Net Lift .561"
Intake Gross Lift .335"
Exxhaust Gross Lift .330"
Duration @ .050"
Also, how do I read the balancing results for the Bobweight card and final spin numbers?
