Remove ECM, wiring, throttle body, intake manifold and fuses.
New parts out of a 350 MAG MPI.
Install new ECM, wiring, intake manifold, injectors,
throttle body and fuses.
No need for matching ECM's or reflushing, rewiring or cam change.
Exhaust and all other parts of the engine are the same between those
We are not talking for a car engine with headers and muflers restricting
the flow. The diameter of that exhaust can support twice that horse
The goal is not the extra 400rpm (and more consuption) BUT MORE
TORQUE at the SAME RPM resulting to more BHP. (due to better
volumetric efficiency from the intake manifold and multi point
Today confirmed my theory with a Mercruiser certified mechanic.
The conversion is possible with no problems.
It will make my engine a 300bhp.
And yes, the 40bhp difference is coming from more torque produced at the
same rpm due to the manifold, throttle body and more precise injection.
So, if you have a 1996 and up mercruiser block with Vortec heads, go to a
yard and look for 350 MAG MPI leftover parts......
