does someone know what the injectors are stock for a3.4 dohc,I mean the # per hr. or however they are rated. I want to start out fresh but I'm not sure what to order.

Search this stuff next time. It's out there. They are 21lb/hr and are dual-spray pattern injectors.Originally posted by stanleydog View PostJesse M.

Any local chain parts house should be able to order them as well.-60v6's 2nd Jon M.

I was under the impression this site was to exchange idea's and swap information, I had no idea it was somekind of competition to see who is the smartest one on the block. this is my 1st time with f/inj. bit I think I can figure it out.

I don't see how the two responses and lack of responses mean there's some kind of competition to see who is the smartest
The DOHC section of the forums rarely get any traffic because it's a dying platform, and most of the people that visit this section didn't post because they just don't know the lbs/hr of DOHC injectors. You asked what the value was, jman093 posted the reply of :
"They are 21lb/hr and are dual-spray pattern injectors."
You asked where to get them, I said:
"www.gmpartsdirect.com
Any local chain parts house should be able to order them as well."
(I would go rock auto myself)
How was this some sort of smart competition?

Yeah, some people don't run a filter between their brains and fingers on here :/
Yes, you can vary the pressure on them to change flow. That's one of the things the pushrod guys have to watch out for when doing top swaps due to the newer ones running at 55psi vs the old ones of 47.5 psi I believe it is. I think all of the DOHC engine all ran at the same pressure. Unfortunately no one makes an adjustable fuel pressure regulator for our engines, but something like the fuel pressure risers for the import scene might be able to be plumbed in somehow to get the added flow you might need.
