they seemed to run hotter than that size of injector should. i put haisley 5x16s in their place.more hp,no smoke at idle,about the same egt
Dont waste your time and money on the marine 370s. I had a set and hated them. Not much power gained, if any. Smoke, EGTs, and fuel mileage were all worse. I sold them and went to a set of NewEra 370s, they were a much better injector. Save up a couple hundred more and you can get a much better quality injector.
5 x 16s and no smoke? how much timing is high timing?
