hey guys it is me again. i posted earlier about the 6.9 to 7.3 swap. i know one guy said he did it to his truck. looking for a couple of more success stories. i am trying to put a 1984 6.9 with ats turbo, into my 94 7.3 turbo. the blocks are the same are they not? the motor mounts and trannies(zf5) will mount up the same yes? i know use the flywheel and balancer from the 6.9 and the glow plug relay from my 94. is that right? i tore the 7.3 down and it needs rebuilt. this 6.9 is a less expensive option and the mechanic shop is going to guarantee it for 30 days. i should know if it is good in 30 days shouldnt i? any help is much appreciated! thanks!
