Looks like the generic Chinese MSD clone everyone sells under they're own name. I have the 385 version of that which came in my 73 F350 dump truck when I bought it. Been fine for the few years I've owned it, but it's got a tired 275hp 460 in it so not exactly a stress test for a distributor. Although it does keep the plugs clean and this thing burns as much oil as it does gas.
Not sure I'd trust one in anything with any HP.
The Duraspark's are solid, just wish there was something off the self, like an MSD, that actually worked and didn't require quite as much time to set up. Until then, I'll keep running Durasparks. I've considered trying a TMeyer but I need to call them and find out what parts they're using in them. I suspect a 4 pin HEI module but I don't know for sure. One of the problems with the Chinese distributors is they often have a non-standard module that you can't get at the corner parts store.
