12 valve injectors

[mtboggs]

looking into getting a set of injectors and I'm looking for some input. I do a decent amount of heavy towing but my final plans for my truck are to be around 500hp to the wheels what would be a good injector for me? This is a budget build, but I do know 370 marines are out of the question I've been looking at ddp's 75hp injectors and what I've read is good but I'd like some more opinions before I go and spend money. All the info and options are appreciated thanks
