Well , they will WORK , but , you are gonna run rich until you tune it . An AFPR would help until you could get a tune on it ........

Since that's a set of four, you would need four more exactly like it for ECU tuning to do any good. Stock injectors are 22# and 19# for 350 and 305's.

bnoon , you are right , I didnt see that there were only 4 . So thats $200 bucks for a set of injectors . Eyerock , if you want 24#ers , why don't you go to SLP's website and get their 24#ers ? They are $99 for 8 of them .......

I will never buy anything from ebay, you never know what you are getting. Call a motorsports shop that you trust and buy stuff from them.

I'm running 24 lbs/hr injectors from SVO (Ford Motorsports) that I bought through Summit for $225. I had TPIS burn me a chip to compensate for the different fueling characteristics of the larger than stock injectors. There isn't enough adjustability in an adjustable FP regulator to get them to run right, and even then you'd be decreasing fuel pressure, which is never a good thing because it hurts the spray pattern and atomization.
The completed setup runs great.

Sorry, I sent the wrong link. I was looking at a set of 8. Crap, I was hoping the injectors would be cut and paste. If I get an adjustable FPR...will I still need to get the PROM burned?

I'm running 24# injectors with a stock FPR (have used an AFPR as well) I have never had a problem with my 85 or 89 computer using them. I do have a problem with it when the weather is really cold. It actually acts like it needs to be richer. Acts like a carb with no choke. Calibration on the chip more than anything......
