So I got my injectors (370's) from New Era in today. Im on the fence at the moment about the bang for the $. When I first got them I was a little concerned because: a. They were dirty enough to make my fingertips black, b. the bag they came in was dirty and had 295hp crossed out and 370hp written below it..., and c. the copper washers had been crushed already. I called Chuck with these concerns and he stated that they may have been a test batch that got pulled off the shelf and dyno'ed on an engine....a little relief there. All went in well. My idle rpm has dropped a lot, which I understand to be normal for a larger injector, but she is also much quieter. Im not sure how much more boost im building because I was pegging the 35psi gauge with the stockers. There is definitely more pull at the higher rpms... something I felt the stock setup always lacked, but I cant gauge if there is a whole lot more HP....Maybe Im expecting more than what is actually to be? Smoke is a little more prevalent but not too bad....and EGT's, well i still cant hit 1200....the pump is fairly maxed out too.
Questions:
Do stock injectors have 6 holes?
If you run NE 370's, whats your take on them?
Chuck, if you have any input, please chime in (And thanks by the way!)
Sorry for rambling....Mike
I went right from stockers to these, with the stage IV upgrade at the same time. Big jump in power and seat of the pants feel. More smoke, more boost. I put down 366 on the dyno last fall, and my fuel screw is over a turn from runaway yet. I'll take care of that this winter. 
I was 1/2 way thru a sentence when I realized you meant me! 
Fuel mileage is still good too.
