The Summit is the same as all the rest that come from China. Don't let that scare you because they are pretty dang good. I've had one in the 351M in my 75 F250 for about 5 or so years now. Runs like a top.
To me, the HUGE advantage is, IF you have room for that big ole cap, go for it. I say that because replacement parts are available EVERYWHERE. Who doesn't keep a 4 pin Chevy HEI module in stock? Hell, our local WalMart even has them. That's no joke. That's their biggest advantage right there.
Get a Pertronix? Great! Break down on a Sunday afternoon and get back to me. LOL
