I just got my motor together and am going to start putting it in but wanted to know if I can start it without the new power command for the first start. I now have a mrrpm 840 kit,mrrpm cams, new timing chains,and a new full HMF exhaust. I know I now need the fuel controller and I have it but I’m not sure I know enough about the controller yet and thought starting the motor with original controls the first time would tell me it runs ok before tackling the fuel controller.
