What is my injector size?? - Are Racetronix good injectors??
I had another thread going and got mixed information. I had been under the impression that my 95 LT1 6spd had 24lb injectors stock...and was told that in the last thread. But I was also told (and given a chart backing it up from Accel) that my 95 was to use 26lb injectors. So I have no idea what I am supposed to get. - - - I am also wondering if Racetronix are good injectors - as I was told they are better than the Ford/Bosch injectors. - - - I am so confused 
(If the Racetronix are better it is easier for me to get them - not much more $ either).

Yup, your stock injectors are 24lb injectors.. I have a set off a '95 LT1 which I'm using now.
Never heard anything bad about racetronix, their prices are pretty good I think.. There was also a guy on here that was reconditioning injectors and selling them also. Not sure of his name though...

pages 13-14 give that information... However..since I have light mods and am going to get a tuned PCM I might go ahead and get 26lb injectors anyways.. In which case I may very well go with Racetronix. But no one else seems to have recommended them. They are close to $300 for 8 (not a bad price). I think racetronix.com gets you to their site. Let me know what you think. Thanks

I learned over the years to never trust any documents or publications and to trust my own eyes instead. It is not unheard of that data is incorrect. heck go to Autozone, and they'll claim my '85 vette is carburated.
If you do have mods planned for the car, I'd go larger too. 26lbs sounds good, and get a good tune after everything is done..
But it relies on how MUCH of mods you are going to do..

If you're going to buy the Racetronix injectors, I'd recommend buying them matched. I bought a set from Racetronix when
one of my stock injectors internally shorted. I had used the stk injectors for 7 years and all the plugs read identical (all the same color).
After installing the Racetronix injectors, the plug colors were all over the place. From dark tan to bone white. In other words, the injector flow rates
are all over the place. I'm going to replace them with Ford injectors this spring.

hmm - I can't seem to find ford injectors at 26lbs. I was hoping to get new ones that were a little larger in case I did RRs and such. Not sure if I need to be over 24 for that... I think the LT4 uses 28lbs.

Racetronix injectors are Delphi injectors which are what C4's come with from the factory.
Please consider these injectors as a mild upgrade from stock:
http://www.racetronix.com/621020.html
These injectors work well in LT1 & LT4 cars.
Most disc injectors fall within a 3% window which is better than most non-FM Bosch pintle injectors.

32 @ 80% = 25.6
A 33% increase is moderate. The ECM/PCM can be adjusted for a 32 just as easily as a 26. Moving from a 24 to a 26 is a waste of money unless you must replace your factory injectors and you have no intention of making any major HP upgrades.
