Marine injectors 300, 330 and 370s have 155* patterns. Smoke, bad mpg and high cylinder pressure. I’m not saying there horrible just saying there’s much better options out there for the same price or a little more.

Some companys use the 370 nozzle but with the correct 145* spray.

You can find a set of correct spray injectors for half the price of the company you mentioned. Check out or vendors and ask about there budget injectors with correct spray. Stay away from Pensacola diesel. For 500hp I would get a 5x12 aka 370 aka 90hp with correct spray. However if you ever plan on going more then you might as well get a set of 5x14s aka 140hp aka 435s for just a few dollars more.

oh and steer clear of tips and get new injectors.

 

what about getting used injectors? is there generally anything wrong with getting used ones? are they alot less reliable or should I look around for used ones before going to buy new ones? I would like to get to 500 but stay close to that since I have a con fe rated to 550 and I don't wanna have it start slipping if I have more power.

 

buying used ones can be alright. i bought some 370 marines from a guy off here and went and got them pop tested and they said they were in perfect condition. not to mention i got them for $150.

 

Agree'd.. Ive looked at some used injectors too, i dont see anything wrong with buying used as long as they have some kind of proof/receipts to show they are what they say they are. When it comes to that much money i wouldnt take any chances of getting ripped

 

so what would the spray pattern be on the 370 injectors industrial injection sells?
