It's pretty much common sense that supporting mods will be needed. There's also plenty of information out there on these injectors as well. Obviously, anytime mods are done to our cars, do research first. After owning and racing 13 Buick Grand Nationals over the years, I will assure anyone that these injectors are good to run in the 10's with supporting mods.
Right. You just provided full context which is all I was asking for. Newbies buy these cars all the time. If you supply additional fuel through other means (like a 2nd set of injectors), you can run 28 lb injectors to get into the 10s too. But it would be misleading to leave out that fact.
