3406B and C is the first series that used PEEC and had an ECM. Are you sure this is not a 3406B or has been converted? what is your engine number?

No its a 3406c manual. They are the first Motors that had a peec but that doesn't mean that they only had those types of motors I have to 3406 B manual and to 3406 C manual engines for trucks with those types of engines currently and have a 3406e that does have the computer on it
