Msd
looking at the real world results it looks like it on par with a 7al-2 which for 200 bucks is a great deal. i will be buying one for my 73 and watching MPG like a hawk to see what happens.
until then i cant say ya or na on it. upgrading the coil and ignition system other than the driver (box) has big gains. for the cost the MSD streetfire isn't a bad deal.
