Default 370 Injectors or drill out stock ones??

Should I go ahead and go with the 370 marine ones or get the stock ones "drilled out"? A buddy of mine going to school for mechanics said the stock ones are better because they are matched with the pistons, but on the other hand ive been told to go with 370's. What do yall think?

look into sdx njectors.. they will cost you a little more but it is money well spent.

The marine 370s are dirty (poor egts and poor mileage, lots of smoke), but they are CHEAP power. Like the above poster said, SDX are great great sticks and are VERY cheap considering what you get.

the way to go with 370s is get them from someone who modifies them with the correct spray pattern for the truck pistons. DDP does it I think, and a few others.

how much do the DDP 370's go for? So you are saying the DDP 370s dont cause poor mileage/egts/smoke?

sell your stock set and buy a good set of SDX injectors give chris a call, tell him what your goals are for the truck and he will hook you up with what you need. 479-799-3953

I could be wrong, just know I've seen them out there and I thought it was DDP.

dont drill out your stock ones what ever you do. there is alot more to bigger injectors then just takin a drill bit to them and drilling them out.

i hate to sound like a broken record, but i would go with a set of sdx injectors. i laid down 433 and 1156 with them a couple weeks ago, and that was on a stock turbo. from all they have sold, havent heard of one single problem with the injector yet.
