Vvt lock or not

RSM, If you are not going to use the factory ECM and use a carbureted intake with a throttle body injector and some other means of running the ignition and timing. Then the 6.4 cam is the wrong one for for what you are doing, the 6.4 cam makes its best power when set up with its full timing sweep with the VVT. If you do not run the cam that way the engine will lose power. I suggest you get a custom cam and let the cam company know you are eliminating the VVT so they can cut the new cam accordingly so it will work without it and a lockout for the VVT cam timing gear. The VVT, MDS engines are computer operated engine, and you have to converted it to a non computer operated engine.
