ok i found previous post about msd dist. so now i know its there. still, is it a difficult upgrade? are there better ones to try out? please let me know.

 

IIRC, from what I have read, if you have a good 280ZX HEI dizzy/system, then the MSD box is a waste. If you have points, then it's OK, but a swap to Pertronix corrects that too.

I didn't find that an MSD6A added much to my ancient 72 240-based single-points system.

 

thanks man
