I had some warmed over 454's(640hp),one day I had an msd vs t-bolt(msd on 1 of the motors died,it was on a restart after leaving the dock,waiting for friends),ran the PR all day and both motors pulled the same.thats when I came up w/ the 2 weather pack connection system to switch out the msd to the t-bolt in seconds.

Pretty much wraps it up. With proper coating and care MSD distributors will last but better have a spare ignition control box per engine. Like Tyler mentioned If you do go aftermarket go with the Marine Daytona sensors. https://shop.daytonasensors.net/. They come preset for marine environment or you map your curve to optimize your application especially with a SC build. Certain rpm's like X advance. The TB system is a great reliable ignition however you just can't tune. Some good threads on here regarding Daytona also.
