I have had an MZB on my '87 430 auto for several years since the original SEM went south. I have had no problems with timing - just triple check the timing before you fully tighten the flywheel nut and it will be ok.
I did have one problem that drove me nuts. I found that the male/female plug connection was not making good electrical contact - it ran at first then refused to start no matter how hard I kicked it. After much head-banging and thinking I found that I needed to slightly close up the female terminals and everything has been sweet roses since then. Just something to watch out for.
