Yes. Get these in 36 lb/hr @ 3 bar.

You may need a 255 LPH fuel pump to go along with these mods as well. Some people get by on the stock fuel system, but it'll be struggling to keep up with your power. To do it right, I'd suggest doing injectors and fuel pump. If you plan on making more power in the future, skip the 36 lb/hr injectors. Go with the 42 lb/hr or even 60 lb/hr injectors. As long as your tuner know what he is doing, going with a bigger injector than currently necessary will not give you any problems. Ask me how I know, lol.

I wanted to go to 42#'s, but my mechanic had 60#'s at the shop and wound up putting them in. Tuned it up and they were fine. Had no issues.

Well, when I blew my motor (unrelated, weak stock internals) I wanted more power if I was going to spend more money. So the 418 got built and this motor needs the 60#'s, especially if I throw a nitrous shot a it.

Wouldn't be a bad idea. I have a full bolt on 383 ported 241's, and a fairly aggressive cam. I am still running stock injectors.

But I am running very lean, and am on the hunt for some 42#'s. The stockers just maxed with the new cam.

36 @ 3 bar are more than enough for your application, however, you can get these in up to 48 lb/hr @ 3 bar for the same price.
