[DeTomaso] MSD fuel injection

I agree.  My Holley equipped cars have run very well.  The throttle response has been very good.  The fuel consumption has been very good.  As I have stated before, I switched to webers mostly for a new challenge.

I considered EFI, but I wanted a different challenge.

I did EFI because first, in theory, you an do the tuning with your computer rather than taking the carb apart;, and second, because of the intellectual challenge!  Unfortunately, if you listen to this discussion, EFI carries a good bit more frustration inherently.  that' the spirit of the pantera- rather than buy the replacement part online, a lot of us like to engineer a better solution.  When it works, it is very satisfying.  When it doesn't work, I try to remember it is supposed to be fun.
