Default injectors

would it be a good idea to get just the tips or just go for the injectors? Im on a budget and was looking between DDP 140hp nozzles or 435 injectors. any opinions on nozzles vs injectors or those tips or 435's in general?

I will be doing more mods so the truck can handle them but would like to get an idea on injectors first. Im looking to go to about 500hp hopefully at some point

if you want 500Hp then you need to get the injectors. you can pull a lot more power out of the full injectors rather than the nozzles

what kind of budget are we loooking at here? and personaly i wouuldnt go with the 435s. they have the same spray pattern as the 370s which is wrong for our piston bowls. im going with 8x .009s dont go with nozzels either with the boost in presure the bodies tend to leak.

I would like to try and find a used set of big injectors but new 435's are pretty cheap iv seen them for about 400. Id like to stay under or near 500 on them.

well i always had it in my head that there is a marine style 370 with the bad spray pattern and a 370 that has the right spray pattern. new era will tell you they have a correct spray pattern 370. my point is dont get marine injectors. they are cheap but will cost you with how dirty they run.
