I've heard lots of stuff about MSD, but I have had mine for 12 years. Never a single problem. Never failed to start immediately. No failures. No repairs. No tuneups. No nothing. Maybe you need to have the whole MSD package:
MSD #8577 Magnetic Pick-up Distributor
MSD #8203 Blaster Coil
MSD #8920 Ford Tach Adapter
MSD #3119 8MM Silicone Spark Plug Wire Set
MSD #8581 Bronze Distributor Gear
MSD #6420 6AL Ignition Box with Rev Limiter
MSD #8746 RPM Module Kit 6000 - 6800
MSD #8984 Starter Saver w/ Signal Stablizer
My OE Tach works fine. I also have a column mounted aftermarket tach. Both are perfectly calibrated and identical.
