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? |
The only thing thats looks like it will increase HP is the higher compression, cam and exhaust. Maybe 450hp.
How is the ECM tuned if you didn't dyno it??????? |
