Summit usually sells quality components under their own name.
They really don't.
Pretty much anything with the store brand name is going to be cheap China or Taiwan made product built for a customer with no funds to buy a better product. There are exceptions, but not many I've seen.
If you want to save some coin and upgrade to a better part, install a Ford Duraspark factory electronic ignition.

NAPA has one for a 78 F100 w/ 302 for about 70 bucks rebuilt. You can hunt through a salvage yard and find the whole setup in no time down in these parts for about 35 bucks. It's as good or better than the part linked above, and you can buy service parts anywhere on the road. The ignition amplifier is remotely mounted so you don't get heat soak from the engine or vibrations on the electronic components effecting performance and life of parts. HEI, in stock form with GM parts, can break up at higher rpm. These things tend to be made with the cheapest parts available and are not the best thing in the world.
The stock Ford stuff is not only cheaper, but is a better system, imo. And, if you want to, you can use it to trigger an MSD6 ignition box in the future.
If you just want a more reliable ignition and a better spark, it's hard to beat the $

erformance ratio of the stock Ford stuff.
