Engine/Transmission (1994 - 1998) Which injectors?

[Johnstra]

What are the pros/cons of 300, 330, and 370 injectors? I know the spray pattern on the 370s is not optimal for our pistons. What about the 300s and 330s? My exhaust, intake, and turbo are stock and I don't have plans to upgrade them in the near term. No sled pulling or drag racing; just looking for a little more fuel.



Suggestions? TIA!

If that is all you are looking for a #12 or #10 plate may make you happy. you won't have to wory too much about fule pressure.

Delivery valves

If you want a moderated increase in power 191 delivery valves and a cut cam plate will do the trick. I'm running a pretty much hacked off plate and a set of custom laser cut d/V that are cut definitly more than 191s and the truck rips good.

I was also wondering if the 330s had the same pattern as the 370s. they can be had for roughly the same price.

If you don't have a plate now I would definitely go that route before injectors.



Marine injectors do not have a spray angle the same as stock Dodge injectors.

 

[EBansberg]

are you saying that the 330s are marine injectors as well? I wasn't sure on those. I knew the 370s were.

I know nothing about the 330 injectors, I'm curious as well how they compare to the 300s and 370s.

According to the guy who runs DIS up on the south end of Portland not much except they burn a little cleaner than his 370's. However he did state when modified the 330's could make more power than modded 370's. Of course I have no idea for sure.

so same spray angle "problem" I take it. I know many people have no problem with it but for me ... ... ... I guess it still kind of makes me wonder.

The spray angle is not a big deal with 370's until you start running big timing. I ran them for years with no issues that I could see once I pulled the head. Also ran them on a stock turbo'd 215 truck at 500 hp(450 #2) and could see that at 17. 5 on timing it was close to the edge of the bowl, I'd say under 20 on timing you should be fine!
