Help...need advice on best ignition system, carb, timing...

Pertronix flamethrower3 distributor and coil. The distributor upgrade is very reliable. their coil has a much higher recharge rate than an msd coil. msd coil recharge actually isn't that good especially for multi spark at high rpm. I switch and will never go back. My little Cuda with 273 has so much more pep no matter the rpm, she feels like she'll just keep climbing. Btw 45 mph and still chirp 2nd
