the originals are 22 lb/hr units. I'd look on ebay, or another online joint, maybe even scoogin dickey has them, or if you have the coin get 24 lb/hr ones and have a new chip burnt for the car.......

I thought they were 19# in '93 only...then went up the following years. Just like the MAF and PROM chip...'93 only. I could be wrong on the injector, but I'm pretty sure they are 19# for that year. You can go bigger, you just have to tune for it. Not a real big deal, but it should be mentioned.

19# were used in the 305 tpi cars. 22# were used in the 350 tpi and 92/93 LT1's. After 93 the LT1 got the larger 24# injectors...

If you tried to run a 19# injector on a 350 you run the risk of running them really lean at stock fuel pressures. If you jump the pressure up another 10-15 psi you could do it, but then your almost run out of pulse width at high rpm....

Thanks for clearing that up...I remember it being lower and I knew the 305s had the 19...that's why I had it in my head. I apologize for any confusion. But like duh stated, you can get different injectors than stock size and adjust the fuel pressure and tuning to accommodate them...which was really what I was meaning to get at.
