So... I've had a problem for a while, and just figured out the cause. When my (stock) injectors get hot they're losing impedence and grounding out the ECU, which shuts off the engine. Mechanic was going to install new injectors for me but I've decided to do it myself and save money. I'm thinking of going with Ford SVOs but I have a few questions...
Are these straight replacements for the stock injectors?
(I'll be using the same 19 lb/hr size)
Will I need to do anything to the PROM?
What impedence am I looking for?
Do they use the same connectors? If not what do I need?

And basically is there anything I should know before starting this? Any problems I'll run into?
Engine is an LB9, stock.

Really need some help with this... I'd like to order these today as I need the car back asap.
Are these what I'm looking for?

the SVO 19's are perfect. Connector is the same. For imdedence you want 16 but 14-17ish range is good. They will bolt right in, but you wont use the factory clips to hold them to the rail. Just place in manifold and bolt down fuel rails. thats it. Prom does not have to be changed. Yup the summit link is what you want. I personmally have had first hand experience with a stock LB9 and these injectros and the car runs great.

Thanks for the help I ordered them today so hopefully I'll be back on the road soon. Don't quite know what you mean about putting them in but I'm sure i'll understand once I start taking it apart.

put a little oil on your fingertips or WD40 and make sure both 0 rings for the injectors are lubed. PLace all the injectors into the manifold first. Then put the fuel rails on top and screw the rails down with the 4 10mm bolts.

I used the 22 lb. injectors, same body style, and I used the stock clips. They work fine, don't leak, and I'm happy with them. If you need to get some, GM still sells the stock clips.

It seems to me that I installed them all into the fuel rail first, then placed the entire set on top of the manifold and pushed them in.

Need more help-- just installed the Ford injectors today, and realized i'm not sure which connector (from the wiring harness) goes to which injector. Is there any way to check this out? I tried switching them around but couldn't really tell a difference.

doesn't matter which goes where.

Batch fire. All 4 on one side fire at the same time.
I've found that vaseline works better on the o-rings than any type of oil. Easier to pop in and out and have never had a scratched o-ring leaking problem like i've had with just thin/motor oil.

I seem to recall that Vasoline will eventually cause rubber to fail. I wonder if the o-rings are made of rubber....

Mine are made of neoprene. Blue o-rings from GM.

Ok thank you very much. That's a relief I had no idea how I was going to get it right. Now I know why switching them around didn't make a difference. I lubed with engine oil and didn't have any problems, so hopefully I'm okay with that.

how does it run with the Ford injectors?
