Tom, there is a set of used 370's on DTR classifieds right now. I think they were $200

what would be the difference between putting in bigger injectors vs?. grinding the fuel plate? that is to say, why would you do one and not the other?

Probably because I have a stock HX 35 and a stock auto transmission.

sorry, but what i meant was, why get bigger injectors rather than grinding the fuel plate? is there a difference, or do they both mean more fuel?
i'm asking so i can figure out the best move for me to make in this department.

Thats is a very good question...that I dont have a real good answer for.

But, I can tell you this...a buddy of mine is a mechanic and he started out with a #10 GSK and 370's. He went to DDP 4's and he couldnt believe the difference in the truck.

I suspect a fuel plate will not be the same as injectors. Injectors will add fuel at all power levels....not just when you get on the thottle, as with a fuel plate.

If anyone has a better explanation...post away.

Docs got it, here's my spin on it.
The thing is, quality injectors are very expensive but for the most part pump mods are very cheap (some free) so start out with the cheaper mods and work your way up. I'm not sure what your truck is for stock power but you can get quite a large gain from all of them by playing with the pump and keeping your wallet in your pocket. There will come a time that the stock injectors will need to be upgraded to handle the shot of fuel (in the necessary time frame) that a modded P-pump delivers but you shouldn't need to worry about it until you start changing DVs. IMO it takes very few mods to a P-pump to give you more fuel than the stock turbo can handle so unless your planning on changing turbos and doing costly transmission up-grades I would forgo the injector expense.

There you have it...
