i think that was a typo.

Like hammer said, its all in the setup,if your looking for a good boost in power and smoke and are on a budget marine injectors do there job, but if youve got the money to spend go for a more higher end injector.

but if you wont a good bang for your buck marine injectors are pretty well a good bet.

370 marine injectors do not have the correct spray angle for our trucks. 370's have a 155* spray angle our stock injectors have a 145* spray angle. you are better off saving up for a week or two longer and spending 500 on a set with the right spray angle. but like they are saying they do work.

i cant promise this is correct but i thought the 370's only sprayed out of the bowl if your timing was above 17*???

the copper washer that comes with the 370s corrects for the spray pattern issue

Like stated, use thinner washers and you wont have that problem, another thing with the marines is the style of nozzle they use, which will make more power than what what you can get from most injector vendors. SAC>VCO.

If you get marines just get the pop psi setup and run them with the thin washer, takes care of all the issues with them, for the most part.

close enough. 370 may not be the BEST injector but they are a good bang for the buck. they get the job done.

Close enough? The 370 is a micro-blind nozzle, makes very good power, but the angle should match the piston you are using.

I thought you or someone said the 370 is a sac not a micro-blind?
