What would you do ??

what MSD is he buying?

this one? $174 http://www.summitracing.com/parts/MSD-6201/
another $40 for the coil? http://www.summitracing.com/parts/MSD-8202/
or is he going to buy a ready to run dist for ya? $356 http://www.summitracing.com/parts/MSD-8388/?rtype=1

its pretty easy to install the MSD set up.

is putting MSD in going to solve your problem? what exactly is the issue with the ign system? there isn't really that much to a stock ign set up.. have you checked the wiring and grounds? probably something really stupid wrong with it..
